Researchers estimate that coalmining activities contribute to an additional 1,072 annual deaths from cardiovascular diseases, with as many as 703 occurring in areas with mountaintop removal. A primary link between these types of deaths and coal activities appears to be the air pollution associated with mountaintop removal mining.
Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the ground's surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our ...
As coal mining moves to deeper and gassier mines, operators increasingly may remove the gas by pipe drainage prior to mining in order to decrease the amount of air needed for ventilation since achieving the air volumes required is becoming both costly (shafts, fans, stoppings, etc.) and technically difficult.

The main purpose of this study was to analyze the effect of coal mining on the springs in the Yushenfu mining area of China. The results of two springs and hydrological surveys conducted in 1994 and 2015 were compared to study the occurrence and evolution of springs before and after largescale mining. The mechanism of spring evolution and ecological effects of domain evolution were analyzed ...
Apr 22, 2013· In a study published in January 2013 in the American Journal of Agricultural Economics, "Natural Resource Curse and Poverty in Appalachian America," they examined the relationship between coal mining and poverty rates in the Appalachian region (ARC counties).
