What happens to mountains after mountaintop removal?
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”.
What are the human health effects of MTR?
But other studies are making a more direct case for human health effects attributable to MTR mining. In 2011 three new studies showed strong associations between MTR mining and increased cardiovascular disease,15 increased frequency of birth defects,16 and reduced quality of life.
What are the positives and negatives of mountaintop removal?

How much does mountaintop removal cost?
DIGGING. Coal and debris are removed using enormous earth-moving machines known as draglines, which stand 22 stories high and can hold 24 compact cars their buckets. These machines can cost up to $100 million, but are favored by coal companies because they displace the need for hundreds of miners.
How many mountains have been destroyed by mountaintop removal?
500 mountains
Tragically, mountaintop removal mining has already destroyed more than 500 mountains encompassing more than 1 million acres of Central and Southern Appalachia.
How do humans benefit from mountaintop removal?
It Is Cheaper Than Traditional Forms Of Coal Mining The clean coal mining industry looks to reduce atmospheric pollution while also reducing the costs of obtaining the coal that needs to be burned for power. Mountaintop mining, when done correctly, is able to accomplish both of these goals rather effectively.
Is mountaintop removal bad?
The air and water pollution caused by this mining practice, which involves deforesting and tearing off mountaintops to get at the coal, is leading to increases in cardiovascular disease, lung cancer, pulmonary disease, and birth defects, his research shows.
How does mountaintop removal affect the environment?
Contaminants from mountaintop removal even poison the drinking water of downstream communities. And this form of mining makes a twofold contribution to climate change: The forests destroyed in the process no longer store carbon, and the burning of the coal that’s mined releases carbon into the atmosphere.
Is mountaintop removal legal?
Disposal of excess overburden associated with mountaintop removal mining has generally been permitted under Nationwide Permit 21 (NWP 21), which authorizes discharges from surface coal mining activities that result in no more than minimal impacts (site-specifically and cumulatively) to the aquatic environment.
Is it possible to flatten a mountain?
Researchers from Chang’an University in China have warned that dozens of mountains have already been flattened – and this is causing air and water pollution, soil erosion and flooding. They say that this activity is happening on an unprecedented scale. They report their concerns in the journal Nature.
Is coal still mined in Kentucky?
After more than two centuries of commercial mining operations, Kentucky’s domestic supply of coal remains an important component of the Commonwealth’s economy. In 2016, Kentucky ranked as the fourth-highest coal producer in the United States producing 42.9 million tons.
What does mountaintop removal mining look like?
Coal companies first raze an entire mountainside, ripping trees from the ground and clearing brush with huge tractors. This debris is then set ablaze as deep holes are dug for explosives. An explosive is poured into these holes and mountaintops are literally blown apart.
Does strip mining still exist?
Mountaintop removal coal mining, often described as “strip mining on steroids,” is an extremely destructive form of mining that is devastating Appalachia. In the past few decades, over 2,000 miles of streams and headwaters that provide drinking water for millions of Americans have been permanently buried and destroyed.
Why are 700 mountains are to be flattened?
A long, long time ago, an old Chinese peasant named Yu Gong decided to move two inconveniently located mountains away from blocking the entrance to his home. Legend has it he struggled terribly, but ultimately succeeded.
Can mountains be cut?
After engineers have surveyed and mapped roads the mountains must be drilled and blasted to create a level surface for the road to be paved. This method requires roads to be cut into the mountainside which is done by drilling holes deep into the mountain.
How deep are Kentucky coal mines?
In western Kentucky, one shaft mine reaches 1,200 feet below the surface. In room and pillar mining, the most common type of underground coal mining, coal seams are mined by a continuous miner that cuts a network of “rooms” into the seam.
Do they still strip mine?
What is wet mining?
i. A system of mining in which water is sprayed into the air at all points where dust is liable to be formed, and no attempt is made to prevent the air from picking up moisture.
How do I reclaim land after mining?
Reclamation includes the following steps: contouring of land; placement of topsoil or an approved substitute on the graded area; reseeding with native vegetation, crops and/or trees; and years of careful monitoring to assure success.
Do mountains have roots?
The most important point is that mountains have buoyant roots that extend downward into the mantle beneath a mountain range, and that the roots are, in general, about 5.6 times deeper than the height of the range. This result reflects the difference between the densities of average crust and mantle.
How deep can humans mine?
AngloGold Ashanti’s Mponeng gold mine, located south-west of Johannesburg in South Africa, is currently the deepest mine in the world. The operating depth at Mponeng mine ranged from between 3.16km to 3.84km below the surface by the end of 2018.
Why is mountaintop removal bad for the Appalachian Mountains?
The exposed rock leaches heavy metals and other toxics that pose enormous health threats to the region’s plants and animals — and people. The U.S. Environmental Protection Agency estimates that mountaintop removal “valley fills” are responsible for burying more than 2,000 miles of vital Appalachian headwater streams, and poisoning many more.
Where does mountaintop removal take place?
Mountaintop removal takes place primarily in eastern Kentucky, southern West Virginia, southwestern Virginia, and eastern Tennessee. Appalachian Voices commissioned a study in 2009 that showed nearly 1.2 million acres had been surface mined for coal and more than 500 mountains destroyed by mountaintop removal coal mining.
How can the government stop mountaintop removal mining?
The president and federal agencies also have the ability to halt mountaintop removal mining through strict mine permits and strong federal rules. In December 2016, after years of technical review, outreach to states and the industry, and public comments, the Office of Surface Mining, Reclamation and Enforcement finalized the Stream Protection Rule.
Do mountaintop removal sites pollute drinking water?
Communities near mountaintop removal sites frequently experience contaminated drinking water supplies.
