Mining the Mountains. Explosives and machines are destroying Appalachian peaks to obtain coal. In a West ia town, residents and the industry fight over a mountain's fate. Mountain operations, like the Hobet 21 mine near Danville, West ia, yield one ton of coal for every 16 tons of terrain displaced.
Coal mining is a major cause of landuse change in the US, and according to the Energy Information Administration it is expected to remain a key part of the national electricity portfolio until at ...
Coal Mining. Many coals also require washing in a coal preparation plant. The most economical mining method depends on the depth of the coal, its quality and thickness, and the density of the overburden (material above the coal seam). Geology and environmental factors are also important considerations.
The disadvantages of coal are the mining process (the way we get it out of the ground) and pollution that occurs when coal is burned. Great care is taken during mining to protect the environment. A qualified engineer must develop a mine plan and submit a permit to a state agency that oversees the mining .
Impact of Declining Coal Industry. However, coal mines were such a dominant employer in a mining communities that when a mine closed down, the economic effects were often devastating. When a town is so reliant on one major employer, the closure means that local unemployment could often be .
Coal and gas mining in Australia. Mining has always been an important part of the Australian economy. ... The human health impacts of coal are well documented and greenhouse gases that result from burning Australian coal and gas are a major contributor to climate change.
Coal mining has several negative effects on the health of the body that often times go unrecognized or just simply ignored. Many people have died from mining for various reasons such as the collapse of the mines as well as respiratory diseases caused by mining.
Coal Mining. The toll on the physical landscape is severe. One of the most serious impacts of coal mining is acid mine drainage. Acid mine drainage contaminates ground and surface water with heavy metals and toxins exposed by mining. This destroys aquatic ecosystems and water supplies that communities depend on for drinking and agriculture.

BILLINGS, Mont. (AP) — officials approved a 117 millionton expansion of a Montana coal mine after concluding that burning the fuel would have a minor impact on the nation's overall greenhouse gas emissions, according to documents released Thursday.
Coal mining and the environment. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow. Coal washing gives rises to large waste dumps, which may ignite spontaneously and cause air pollution. Water pollution arises from some abandoned mines and waste dumps.
The booklet discusses the environmental aspects of metal mining and illustrates the ways science and technology assist in preventing or reducing environmental impacts; Coal Mining and Transportation (Webpage), Energy Information Administration Webpage describing different methods used for mining, processing, and transporting coal.
Social and Economic Benefits of Coal Mining. Often ignored are the social and economic benefits of coal mining. These benefits go far beyond the energy it provides and the products like steel and cement that are made from coal.
