How do they do mountaintop removal?
Mountaintop removal is any method of surface coal mining that destroys a mountaintop or ridgeline, whether or not the mined area will be returned to what is legally described as the “approximate original contour.” Methods of mountaintop removal coal mining include, but are not limited to: cross-ridge mining, box-cut ...
What mineral is extracted in mountaintop removal mining?
Michael Hendryx: Mountaintop removal is a form of surface coal mining. As the name suggests, it literally removes up to 800 feet off the tops of mountains to try to reach coal seams that are not accessible by other mining techniques because the terrain is too steep or the veins are too thin.
What is done with the overburden waste rock that is removed from mountaintop removal sites?
The overburden from MTR is either placed back on the ridge, attempting to reflect the approximate original contour of the mountain, and/or is moved into neighboring valleys. Excess rock and soil containing mining byproducts are disposed into nearby valleys, in what are called "holler fills" or "valley fills".
How is coal extracted from mountaintop removal mines 2?
Answer: Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. ... Explosives are used to remove up to 400 vertical feet (120 m) of mountain to expose underlying coal seams.
What is the solution to mining?
In situ leaching (ISL), also known as solution mining, or in situ recovery, involves leaving the ore where it is in the ground, and recovering the minerals from it by dissolving them, and then pumping the pregnant solution to the surface where the minerals are recovered.
Is strip mining the same as mountaintop removal?
Mountaintop removal mining devastates the landscape, turning areas that should be lush with forests and wildlife into barren moonscapes. ... Mountaintop removal coal mining, often described as "strip mining on steroids," is an extremely destructive form of mining that is devastating Appalachia.
What are 2 toxic chemicals that come from mountaintop removal?
3 Slurry, the residue from cleaning the coal, is impounded in ponds or injected into abandoned underground mine shafts, where it can leach potentially toxic constituents such as arsenic, lead, manganese, iron, sodium, strontium, and sulfate that ultimately may end up in groundwater.
Does mining destroy mountains?
Tragically, mountaintop removal mining has already destroyed more than 500 mountains encompassing more than 1 million acres of Central and Southern Appalachia. ...
How is coal extracted?
Economically, surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as much coal can be extracted per worker, per hour, than is possible with underground mining. The environmental impacts of surface mining are dramatic.
Is mountaintop mining still legal?
Mountaintop mining is regulated under several laws, including the Clean Water Act (CWA) and the Surface Mining Control and Reclamation Act (SMCRA).
Is mountaintop removal illegal?
Mountaintop removal is destroying hundreds of miles of irreplaceable Appalachian streams with mining waste and debris. ... "The Corps has been violating the law by allowing the coal companies to mine under illegal permits that put our local economy at risk."
Is mining destroying the Earth?
Sand mining destroys habitats, dirties rivers and erodes beaches, many of which are already losing ground to rising sea levels. When miners dig out layers of sand, riverbanks become less stable. The pollution and acidity can kill fish and leave less water for people and crops.
Why is mountaintop removal bad?
The impacts on communities of blowing up mountains and dumping the rubble into streams are profound. It forces residents to contend with contaminated drinking water, increased flooding, dangerous coal slurry impoundments, and higher rates of cancer and other health issues.
How does mountaintop removal mining work?
“Mountaintop removal/valley fill is a mining practice where the tops of mountains are removed, exposing the seams of coal. Mountaintop removal can involve removing 500 feet or more of the summit to get at buried seams of coal. The earth from the mountaintop is then dumped in the neighboring valleys.”
