Mining Effects & Problems

Mining: Negative Effects On The Environment, Animals & Humans (+ Some Potential Solutions)

Mining (oil and gas, coal, and metal ore mining in particular) is a sector that receives consistent environmental criticism.

On one hand, mining provides jobs, economic boost, and valuable resources.

On the other hand, there’s concerns over land, water and air pollution, and harm to wildlife and ultimately humans (health, invasion of land rights, and so on)

In this guide we look at some of the negative effects of mining, potential solutions and mining site restoration.

 

Summary – Negative Effects Of Mining

  • Mining has it’s pros and cons
  • On one hand, mining provides jobs and income, stimulates the economy, and provides us with critical resources such as fossil fuels for energy production, and metal ores (for metals) for a range of applications. It is especially useful if we can’t get access to these resources by growing them in a lab, or other via other means
  • In some developing countries for example, mining is the only source of employment, income and livelihood for some people (they depend on it to survive)
  • But, on the other hand, mining can have wide ranging negative effects on the environment, wildlife and humans
  • In many countries, mining is one of the leading sectors that produces general waste, along with the construction sector
  • In some countries, mining is responsible for significant amounts of water use, as well as water waste
  • Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air pollutants. This can lead to air pollution via air contaminants, release of greenhouse gases like methane and CO2, leaching of toxic chemicals into freshwater sources like rivers, lakes and streams, or dumping straight into the ocean, and degradation of huge amounts of land and soil (leading to soil erosion, soil contamination, damage to soil structure etc.). Sedimentation can be an issue where displaced soil gets into water sources and creates issues, as can subsistence be an issue, where land that has been dug out can collapse. Lowering of the water table, and coal fires (which can last a long time) can be an issue at some mines. Mining also uses a lot of water and electricity, and other energy for on-site mining equipment and vehicles – so it isn’t great from a sustainability perspective. Mining can also be one of the causes of deforestation in some regions. The end product of oil and gas (and coal mining) is also linked heavily to climate change i.e. the burning of fossil fuels leads to carbon dioxide and other emissions
  • From a wildlife perspective, there can be a loss of habitat, elimination of species numbers (from land clearing and contamination of water and soil), and loss of biodiversity.
  • From a human perspective, mining workers’ lives and safety can be at risk in a number of ways. Some mines are reported for gross human rights violations and for exploiting workers in dangerous conditions or by exposing them to hazardous air and chemicals), and local populations can be displaced or their health put at risk from exposure to mining waste or the chemicals it releases.
  • From a cost perspective, not only can mining operations and on-site expenses be huge, but mining exploration and testing mining sites can be very expensive too
  • Some mining land sites can never be restored to be anything valuable post mining activity – but, some can be restored in different ways (such as being made into parks). Some say mining site restoration funds would be better spent buying separate land elsewhere and building up that area for plant/tree life, wildlife and environmental conservation i.e. the mining restoration process can be re-thought and improved
  • Mining has improved in the last few decades in developed countries, but some developing countries lag far behind in making improvements
  • Mining can get better in some ways … some of those ways might include …
  • Better environmental, social and wildlife benefit/cost assessments done before readying a mining site, better treatment/sterilization, dumping and management of tailing waste, better reporting on all facets of mining (waste generation and management, pollution and environmental degradation, habitat displacement, worker and local community rights and safety, economic performance, and so on), treat and recycle mining waste where possible (for example – water waste), use of renewable energy on mining sites over diesel fuel where possible, targeting unregulated, illegal or poor performing mines, having better and more transparent reporting of environmental and human health indicators from mining sites around the world, ensuring proper backfilling and mining site clean ups take place after mining operations finish, encouraging sustainable and responsible mining practices, improving mining legislation and regulations, looking at beneficial mining taxes, introducing certifications for various types and levels desired mining practices, have zero fatality and zero serious injury goals for mining worldwide, and look at ways to improve land rehabilitation practices after mining (and have better awareness of irreversible effects of establishing a mining site in a specific location – weigh up against the benefits of establishing that site)
  • On a society wide level – the use of renewable energy for electricity production and transport may reduce the need for fossil fuel mining, and more efficient recycling and re-use of already mined metals may reduce metal ore mining. We might also look at above ground alternatives to the resources we currently mine – lab grown resources and science might be able to help us in this regard
  • Mining provides a valuable service and valuable materials to society, but, it appears there is room for improvement in the industry to reduce it’s negative effects – especially in some regions more than others

 

What Is Mining?

  • Mining is the extraction of valuable minerals or other geological materials from the Earth.
  • Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
  • Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

– wikipedia.org

 

Different Types Of Mining

The main types of mining are surface mining, and underground mining [ … Today, surface mining is much more common, and produces … 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores]

Mining operations can be grouped into five major categories in terms of their respective resources. These are:

  • oil and gas extraction,
  • coal mining,
  • metal ore mining,
  • nonmetallic mineral mining and quarrying,
  • and mining support activities.

Of all of these categories, oil and gas extraction remains one of the largest in terms of its global economic importance.

– wikipedia.org

Coal mining also receives attention for having a significant impact on the environment and wildlife.

 

Dependency On, Importance Of, & Composition Of The Mining Industry Worldwide, & In Different Countries

Worldwide

  • The dependency of various high-tech-industries on rare earths is a recent issue 
  • Coal … is still one of the leading global energy resources.
  • Consequently, the mining sector is pivotal to the world’s economy.
  • The global top 40 companies, which represent a vast majority of the whole industry, reported some 496 billion U.S. dollars of revenue in 2016.
  • In terms of volume, the most exploited commodities worldwide are coal, iron ore, bauxite, and potash.
  • China and the United States are the top coal producing countries.
  • Iron ore mining is also dominated by China, with Australia in second place.
  • Thus, China is becoming the top mining country for many commodities, especially for the highly demanded rare earths, of which China produced over 83 percent of the global production in 2016.
  • Additionally, China is the world’s leading country in the mine production of gold.

– statista.com

 

United States

  • In 2016, there were a total of 13,089 mining operations that reported mine operator employment.
  • The commodity breakdown was 1,289 coal, 306 metal, 906 nonmetal, 4,298 stone, and 6,290 sand & gravel mines.

– cdc.gov

 

  • In the United States, mining has always played an important role. Its relevance increases all the more whenever mining includes the extraction of oil and gas, and support activities for mining, as some sources do.
  • The total U.S. mining gross output in 2015 amounted to 449 billion U.S. dollars, a notable decrease from the gross output in the previous year.
  • In the same year, the whole sector employed around 748 thousand people.

– statista.com

 

Australia

According to the Australian Bureau of Statistics (ABS) June 2011 Labour Force Survey, the top three sectors for employment within the mining industry are:

  • Metal Ore Mining; 71,700 people; 34.8 per cent
  • Coal Mining; 48,500 people; 23.6 per cent
  • Exploration; 27,300; 13.3 per cent

What Does The Mining Process Generally Involve?

Generally it involves:

  • Prospecting for ore bodies or other resources
  • Analysis of the profit potential of a proposed mine
  • Extraction of the desired materials, and
  • Final reclamation of the land after the mine is closed (the process of restoring land that has been mined to a natural or economically usable state)

 

Negative Effects Of Mining On The Environment, Wildlife & Humans

There are different practices and different regulations and laws for mining in different countries. Therefore, the effects of mining and problems created will be different from country to country.

Mining can have negative environmental (water, land, air, wildlife), and human (safety, human rights, injury, death) effects.

 

Environmental & Wildlife Effects

  • Land degradation and Soil erosion
  • Formation of sinkholes
  • Loss of biodiversity [as a side effect from habitat loss and land clearing/land degradation]
  • Contamination of soil, groundwater and surface water by chemicals from mining processes
  • Forest logging [in some cases]
  • Contamination resulting from leakage of chemicals [which can also affect the health of the local population if not properly controlled]
  • Extreme examples of pollution from mining activities include coal fires, which can last for years or even decades, producing massive amounts of environmental damage.

– wikipedia.org

 

  • Coal mining … can cause deforestation and releases toxic amounts of minerals and heavy metals into the soil, water sources, as well as potentially human water supplies
  • The effects of mining coal persist for years …
  • Bad mining practices can ignite coal fires, which can burn for decades, release fly ash and smoke laden with greenhouse gasses and toxic chemicals.
  • Mining releases coal mine methane, a greenhouse gas 20 times more powerful than carbon dioxide.
  • Acid Mine Drainage affects the environment and human lives in South Africa

Strip Mining has extensive environmental impact …

  • Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land.
  • When rain washes the loosened top soil into streams, sediments pollute waterways. This can hurt fish and smother plant life downstream, and cause disfiguration of river channels and streams, which leads to flooding.
  • There is an increased risk of chemical contamination of ground water when minerals in upturned earth seep into the water table, and watersheds are destroyed when disfigured land loses the water it once held.
  • Strip mining causes dust and noise pollution when top soil is disrupted with heavy machinery and coal dust is created in mines.
  • Land restoration is also an issue with strip mining

Underground Mining has extensive environmental impact …

  • Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water.
  • It causes subsidence as mines collapse and the land above it starts to sink. This [can cause] serious damage to buildings.
  • It lowers the water table, changing the flow of groundwater and streams.
  • [It can also waste water] – In Germany for example, over 500 million cubic metres of water are pumped out of the ground every year. Only a small percentage of this is used by industry or local towns – the rest is wasted. What’s worse is that removing so much water creates a kind of funnel that drains water from an area much larger than the immediate coal-mining environment.
  • Coal mining also produces greenhouse gas emissions.

  • Unregulated mining has the potential to release harmful substances into the soil, air, and water.
  • In Open Pit Mining … Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and liquid, are produced as tailings, toxic and radioactive elements from these liquids can leak into bedrock if not properly contained.
  • Underground mining – has the potential for tunnel collapses and land subsidence
  • Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water. As water takes on harmful concentrations of minerals and heavy metals, it becomes a contaminant. This contaminated water can pollute the region surrounding the mine and beyond
  • Mercury is commonly used as an amalgamating agent to facilitate the recovery of some precious ores. Mercury tailings then become a major source of concern, and improper disposal can lead to contamination of the atmosphere and neighbouring bodies of water.
  • Most underground mining operations increase sedimentation in nearby rivers through their use of hydraulic pumps and suction dredges; blasting with hydraulic pumps removes ecologically valuable topsoil containing seed banks, making it difficult for vegetation to recover
  • Deforestation due to mining leads to the disintegration of biomes and contributes to the effects of erosion.
  • Insitu Leach Mining … has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock. There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process. However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well. The fluids remaining after the leaching process commonly contain elevated concentrations of metals and radioactive isotopes, posing a significant risk to nearby ground and surface water sources. Additionally, the low pH of ISL mining wastewater can result in acidification of the surrounding environment.
  • Other types of mining that can result in environmental damage are Heap Leaching and Brine Mining
  • Specific contaminant materials from the mining process are Radionuclides, and Dust & Metal
  • Additional environmental issues with mining are Carbon Output (causing air pollution), Erosion (causing land pollution) and Endangered Species Habitat, Water Use and Wastewater (using water and polluting water)
  • Case studies on negative environmental impacts of mining can be found for Greenland, China, and Molycorp
  • The cost of inaction/action with mining when it comes to environmental damage is:
  • If no action is taken to remediate the many environmental problems inherent to modern mining, the end cost for governments and communities would be devastating. Already mines in China release 9,600 to 12,000 cubic meters of toxic gas containing flue dust concentrate, hydrofluoric acid, sulfur dioxide, and sulfuric acid for each ton of rare earth elements produced. Additionally, nearly 75 cubic meters of acidic waste water and one ton of radioactive waste residue are generated

  • Environmental contaminants associated with mining activities may affect wildlife species in many ways and at many levels within the ecosystem.
  • Some contaminants associated with mines (e.g., lead, arsenic, cyanide, etc.) may cause acute or chronic effects on resident wildlife.
  • Tailings and associated heavy metal contamination are dumped from mining sites, and can cause negative impact on wildlife, and also cause water pollution

– umesc.usgs.gov

 

Mining affects the environment and wildlife in the following ways:

  • Habitat Loss – when the land is cleared before mining. This can involve deforestation/clearing of forests and trees. Animals lose their immediate habitat, and must relocate to another habitat. Animals also lose shade from the sun, and cover from predators. Explosions on mountain tops and mountain mining can also cause habitat loss for some animals. [Sediment from mining site clearing can find it’s way into rivers and change river habitats for aquatic species]
  • Pollution – Toxic chemicals and minerals from mining could go to streams, rivers, and other bodies of water which can create harmful effects to marine species. The mining process exposes bodies of water to heavy metals and toxic minerals like selenium which can negatively impact the human and the marine wildlife lives.
  • Water Loss – Mining can cause the water table to shrink. Water often seeps into areas that contain coal and other valuable products, and that water needs to be pumped out of the mine to allow the miners to work. Aside from pollution, the process would also cause water loss in the ground. Some mines have to collect water for use as a dust suppressant, which puts more strain on the local water supply. Nearby residents who depend on wells for their water supply can also get affected. They will need to drill even deeper to ensure that they have access to water. When the water loss from mining is combined with another large source of strain on the supply, it can lead to a shortage, which can contribute to the destruction of ecosystems.
  • Abandoned Mines  – contaminants are left on site sometimes, and subsistence can happen whereby the mine isn’t backfilled adequately, and the soil can collapse

  • [Mining has resulted in] social conflict, human rights violations and environmental devastation across Asia, Latin America and Africa …
  • Colorado in the US has experienced a toxic spill from an old gold mine
  • A new atlas of 600 international mining and oil companies has identified more than 1,500 ongoing conflicts raging over water, land, spills, pollution, ill-health, relocations, waste, land grabs, floods and falling water levels [across the world]

– theguardian.com, and ejatlas.org

 

  • Often mines for gold, copper and titanium create holes in the earth that are miles wide, thousands of feet deep and pollute groundwater and endanger natural habitats of wildlife and animals over wide areas.
  • Local governments are often swayed by the large mining corporations with promises of jobs and other financial rewards and ignore the costs to health and the environment.

– onegreenplanet.org

 

Waste generated from mining:

  • Ore mills generate large amounts of waste, called tailings [These tailings can be toxic]
  • For example, 99 tons of waste are generated per ton of copper, with even higher ratios in gold mining – because only 5.3 g of gold is extracted per ton of ore, a ton of gold produces 200,000 tons of tailings. (As time goes on and richer deposits are exhausted – and technology improves to permit – this number is going down to .5 g and less.)
  • Tailings, which are usually produced as a slurry, are most commonly dumped into ponds made from naturally existing valleys.
  • These ponds are secured by impoundments (dams or embankment dams).
  • In 2000, it was estimated that 3,500 tailings impoundments existed, and that every year, 2 to 5 major failures and 35 minor failures occurred; for example, in the Marcopper mining disaster at least 2 million tons of tailings were released into a local river.
  • In central Finland, Talvivaara Terrafame polymetal mine waste effluent since 2008 and numerous leaks of saline mine water has resulted in ecological collapse of nearby lake.
  • Subaqueous tailings disposal is another option.
  • The mining industry has argued that submarine tailings disposal (STD), which disposes of tailings in the sea, is ideal because it avoids the risks of tailings ponds; although the practice is illegal in the United States and Canada, it is used in the developing world.
  • The waste is classified as either sterile or mineralised, with acid generating potential, and the movement and storage of this material forms a major part of the mine planning process.
  • [Tailing waste should be treated, dumped and managed in a safe and non hazardous way]

– wikipedia.org

 

Use of energy in mining:

  • Many mining sites are remote and not connected to the grid.
  • Electricity is typically generated with diesel generators.
  • Due to high transportation cost and theft during transportation the cost for generating electricity is normally high.

Human Safety – Human Rights, Injury, & Death

  • [Currently there are] 142 disputes involving gold mines, 130 at coal mines, 96 at copper mines and 73 at silver mines, with India, Colombia, Nigeria, Brazil, Ecuador, Peru and the Philippines having the most. They ranged from longstanding legal disputes to armed conflicts.
  • The companies whose mines have attracted the most accusations of human rights abuses and environmental conflict are some of the largest in the world, mostly listed on the London stock exchange. They include AngloGold Ashanti, Rio Tinto, Barrick Gold, BHP Billiton, Glencore Xstrata and Newmont Mining. Between them they are involved in 75 conflicts in countries ranging from Colombia, Burma and the Democratic Republic of the Congo to the US, Zambia and the Philippines, says the database.

  • Safety has long been a concern in the mining business, especially in sub-surface mining.
  • While mining today is substantially safer than it was in previous decades, mining accidents still occur.
  • Government figures indicate that 5,000 Chinese miners die in accidents each year, while other reports have suggested a figure as high as 20,000.
  • Mining accidents continue worldwide, including accidents causing dozens of fatalities …
  • There are numerous occupational hazards associated with mining, including exposure to rockdust which can lead to diseases such as silicosis, asbestosis, and pneumoconiosis. Gases in the mine can lead to asphyxiation and could also be ignited. Mining equipment can generate considerable noise, putting workers at risk for hearing loss. Cave-ins, rock falls, and exposure to excess heat are also known hazards. 
  • Coal mines had the highest hearing loss injury likelihood.

– wikipedia.org

 

  • Soaring worldwide demand for the minerals used in electronic devices such as smartphones and laptops has left a legacy of social conflict and human rights violations across Asia, Latin America and Africa.

– theguardian.com

 

  • The amount of mining fatalities among 28 of the world’s 40 largest miners which disclosed their safety statistics has reduced by 37 per cent.
  • Out of 22 companies which reported injury frequency rate statistics, 15 reported improvements or remained consistent in 2017 with the previous year.
  • More than half of the fatalities disclosed occurred in markets such as India and South Africa.

  • Coal dust inhalation causes black lung disease among miners and those who live nearby
  • Mining accidents kill thousands every year.
  • Coal mining displaces whole communities, forced off their land by expanding mines, coal fires, subsidence and contaminated water supplies.
  • Common health threats posed by coal mining are:
  • Pneumoconiosis, aka black lung disease or CWP, is caused when miners breathe in coal dust and carbon, which harden the lungs. Estimates show that 1,200 people in the US still die from black lung disease annually. The situation in developing countries is even worse.
  • Cardiopulmonary disease, chronic obstructive pulmonary disease, hypertension, lung disease, and kidney disease have been found in higher-than-normal rates among residents who live near coal mines, according to a 2001 US study.
  • Toxic levels of arsenic, fluorine, mercury, and selenium are emitted by coal fires, entering the air and the food chain of those living nearby.
  • Mine collapses and accidents kill thousands of workers around the world every year. Chinese coal mine accidents killed 4,700 people in 2006.

Greenhouse Gas Emissions From Mining

  • Greenhouse Gas Emissions – Mining is one of the most common methods for extracting fossil fuel from the ground. Fossil fuels can be used to power mining machinery. Although useful, burning fossil fuels release greenhouse gasses into the air which contributes to climate change. Many mines produce methane as a waste product. Methane is a relatively potent greenhouse gas; even a small amount of it can gradually worsen climate change. Coal mines are responsible for approximately six percent of the methane that is released due to human activities.

Potential Solutions To The Negative Effects Of Mining

Given that fossil fuel and metal ore mining are two of the more common types of mining, two avenues to explore that might reduce the negative effects of mining are:

  • Focus on how using renewable energy can reduce fossil fuel mining, and
  • Focus on how recycling and re-using metals already mined out of the ground and in use can save us from future metal ore mining (this will be particularly important in the future with the heavy use of batteries for energy storage and electric cars)

 

Apart from that, some other potential solutions to look at to reduce the negative effects of mining might be:

 

Potential Solutions To Wildlife Problems

An assessment on the local wild life can also be done prior to mining operations taking place to assess the risks in starting mining operations.

But, once an area is mined – there’s not a lot that can be done apart from restoring habitats in the mining site restoration process.

Some effects of mining might be irreversible, such as species elimination from a particular area.

 

Potential Solutions To Environmental Problems 

Various groups are promoting environmentally-friendly mining. Among the proposed ideas include the following:

  • Shutting down or heavily penalising unregulated and illegal mines (especially in poorer or less regulated countries)
  • Enforcing accurate reporting of dumped toxic wastes
  • Enforce proper management and treatment of all mining waste
  • Backfilling mine sites and proper waste clean-up
  • Encouraging and investing in the development of sustainable mining technology
  • Improving mining legislation and regulation (emissions and air tax, land tax, water tax, etc.)

Responsible mining [in addition to helping the environment and wildlife] … can also ensure the safety of the people working in the mine and living in nearby areas.

– pegasusfoundation.org

 

  • Mission 2016 proposes that governments enforce regulations on companies and use cutting-edge technology to reduce the damage from mining-related sources.
  • Mission 2016’s plan will increase recycling efforts, greener mining and refining techniques, reduce the cost of environmental damage on the surrounding community, and increase government involvement in the regulation of dirty mining practices.

– web.mit.edu

 

  • Preemptive actions such as stricter regulations and proper waste disposal strategies can reduce the costs of environmental damage, and in some cases pay for themselves.
  • For example: the US company Molycorp spent 10 million USD on its paste-tailings operation, but the water and chemical reagents it was able to recycle saved have already paid for the instalment, in addition to generating less waste. “Although the operating cost of the paste tailings operation is expected to be greater than it would be for a tailings pond… we expect that increased water recycling and reduced environmental risks associated with the paste tailings facility will ultimately mitigate that additional cost”

– web.mit.edu

 

  • Signatures on petitions can stop mining in areas under serious threat – this has been done in Cambodia, India and Alaska for example

– onegreenplanet.org

 

Currently, these are some of the standards and regulations in place for protecting the environment from mining practices:

  • [Having mining financing standards] in an effort to improve social and environmental performance in the mining and metals industry internationally 
  • The mining industry has provided funding to various conservation groups, some of which have been working with conservation agendas that are at odds with an emerging acceptance of the rights of indigenous people – particularly the right to make land-use decisions.
  • Certification of mines with good practices … [although certification processes have been accused of lacking rigor, or are voluntary and unverified in some cases]
  • … provide evidence on policies managing ecological costs and maximise socio-economic benefits of mining using host country regulatory initiatives

– wikipedia.org

 

  • Renewable energy applications are becoming an alternative or amendment on mining sites
  • Both solar and wind power plants can contribute in saving diesel costs at mining sites. Renewable energy applications have been built at mining sites.
  • Cost savings can reach up to 70%.

– wikipedia.org

 

Potential Solutions For Human Safety

In developing countries, companies and countries as a whole can enforce basic human and working rights for mining workers.

As far as funds will allow, developing country mining practices can start emulating developed country safety practices in meeting safety regulations.

 

Some specific human safety goals might be:

  • Have a zero fatality goal for mining worldwide
  • [Have a zero serious injuries goal for mining worldwide]
  • Continue to develop automated technologies [which are] aimed to increase efficiency and reduce human involvement in high safety risk operations
  • More comprehensive and detailed safety reporting from countries and businesses – China in particular [and better disclosure of safety statistics by companies]
  • … renewed attention on safety performance

– australianmining.com.au

 

  • Have robust safety procedures
  • Minimise worker fatigue
  • Involve workers in safety planning and management more often and more closely
  • Have comprehensive risk assessment
  • Have in-depth incident investigation
  • Have comprehensive pre mining activity safety assessments
  • Protecting the human rights and employee rights of mining workers and local populations

– informa.com.au

 

  • [Some countries] provide intervention strategies regarding occupational health and safety issues. The Mining Safety and Health Administration (MSHA) was established in 1978 to “work to prevent death, illness, and injury from mining and promote safe and healthful workplaces for US miners.” Since its implementation in 1978, the number of miner fatalities has decreased from 242 miners in 1978 to 28 miners in 2015.
  • Proper ventilation, hearing protection, and spraying equipment with water are important safety practices in mines.

Land Rehabilitation After Mining

Mining companies in some countries are required to follow stringent environmental and land rehabilitation regulations.

However, sometimes, some of the effects of mining are irreversible, or can take a long time to restore back to pre-mining conditions … even after land rehabilitation.

 

In some countries, land reclamation may involve:

  • an environmental impact assessment
  • development of an environmental management plan
  • mine closure planning (which must be done before the start of mining operations)
  • and environmental monitoring during operation and after closure

However, in some areas, particularly in the developing world, government regulations may not be well enforced.

– Wikipedia.org

 

  • Since 1978 the mining industry has reclaimed more than 2 million acres (8,000 km²) of land in the United States alone. This reclaimed land has renewed vegetation and wildlife in previous mining lands and can even be used for farming and ranching.

– Wikipedia.org

 

  • Restoration ecologists increasingly accept that it is not practically possible to replace what has been destroyed [once an area has been mined].
  • Rather than trying to paper over the cracks with mine restoration, it might be more effective to divert funding from mine site rehabilitation programs and use the money to buy and manage public and private nature conservation reserves.
