Mine Water Pollution: The mining Industry has to discharge millions of gallons of water every day to the adjacent water courses thereby may cause water pollution problems in and around the mining areas. Mine water discharge also forms the main source of various water supplies particularly potable in the thickly populated coal fields.
By diverting surface water and pumping groundwater, mining operations can reduce both the quantity and quality of water available downstream for aquatic ecosystems and other industrial and municipal water users, especially in areas with arid climates.
Experts have called the water that drains from the mine quot;world''s worst waterquot;. Besides world record levels of acidity, the water also contains heavy water pollution from the mine has caused severe damage to the surrounding river habitat.
Removal of vegetative cover is often followed by massive soil erosion, siltation of river and reservoirs. The direct impacts on the living organisms in the mining areas may range from death of plants and animals due to mining activity or contact with toxic wastes and mine drainages, disturbance of wildlife habitat due to blasting and heavy machines.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
How to Control Pollution in Mining Industry?
Nonstop pollution for millenia. Fuelled by rainfall, there is a nonstop flow of water contaminated with acid and heavy metals from the mine. And no solution in sight to stop the pollution. A common problem. Acid that drains from mines is a very common problem in mining. It is also one of mining''s most severe and important environmental challenges.
Such compensation allegedly arising from environmental pollution due to gold mining and prospecting activities carried out by illegal artisanal miners in Siga Hills, Nyang''hwale District, Geita
Dec 17, 2020#0183;#32;Legacy mining pollution in Zambia is the result of many decades of unsustainable mining operations and inadequate rehabilitation or closure of mining sites. In the Copperbelt Province, townships adjacent to copper mining sites are severely polluted while in the old mining town of Kabwe, there are unacceptably high levels of lead in the soil.
Jul 19, 2018#0183;#32;The environmental problems arising due to mining activities are natural land degradation, air and water pollution with heavy metals, organic and in organic waste, negative
Jan 23, 2017#0183;#32;Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.

Historically, coal mining has had a significant impact on the environment and there is substantial evidence of a strong link between environmental pollution from mining activities and the health and wellbeing of humans and ecosystems in the surrounding vicinities.
Environmental impact of the oil shale industry includes the consideration of issues such as land use, waste management, and water and air pollution caused by the extraction and processing of oil shale. Surface mining of oil shale deposits causes the usual environmental impacts of openpit addition, the combustion and thermal processing generate waste material, which must be disposed
The Comptroller and Auditor General of India (CAG) has pointed out serious air, water and environmental pollution caused by illegal mining being carried on in various parts of the state of Meghalaya. There was serious air, water and environmental pollution caused by illegal, unregulated and indiscriminate miningbeing carried on in various parts of the state of Meghalaya, said the CAG report.
Pit lakes Production of acid mine drainage (AMD) with pH values below 3 and high dissolved concentrations of sulphate and metals is a common problem in sulphide mine pit lakes. Thus, pit lake water quality is one of the most significant environmental issues facing the global mining industry today.
Noise Pollution and Its Control in Mining. The noise is now being recognised as a major health hazard; resulting in annoyance, partial hearing loss and even permanent damage to the inner ear after prolonged exposure. The problem underground is of special importance because of the acoustics of
Mining pollutes the groundwater. Sulphur, usually present as an impurity in many ores is known to get converted into sulphuric acid through microbial action, thereby making the water acidic. 4. Surface water pollution: Sulfur in one react with water and oxygen to form sulfuric acid which leaks out from the mine.
Jul 07, 2013#0183;#32;Mining inevitably leads to a lot of waste rock being extracted alongside minerals. It''s why mines often cause more damage to the land than they should. Scientists are working on various initiatives to reduce the amount of waste rock through a rock selection process. One option is explosivefree breaking.
Fossil fuel emissions from power plants which burn coal as fuel contributed heavily, along with vehicles burning fossil fuels, to the production of smog. Smog is the result of fossil fuel combustion combined with sunlight and heat. The result is a toxic gas which now surrounds our once pristine planet.
