Health Hazards of Mining and Quarrying

Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods.

The Hazards of 19th Century Coal Mining eHISTORY

There were two big engineering problems in mining coal underground: A system to drain water from the mine ; A system to ventilate the mine and to provide fresh air to the miners. A special problem in coal mines was the methane (a gas) that sometimes accompanied coal, and which could--and too often did--catch fire and explode.

ENVIRONMENTAL RISKS OF COAL REFUSE SLURRY

The additional vertical load exerted on a mine barrier from weight of cap material theoretically could cause an underground mine breakthrough. Cap material is commonly comprised (from top to bottom) of 6-36 inches of top soil, 12-24 inches of compacted soil, and 2-30 feet of coarse coal refuse and/or mine spoil (Shinavski, 2006).

Environmental Risks of Mining

Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
