Coal of high rank (e.g., high carbon content such as anthracite) is associated with a higher risk of cwp. there are some rheumatoid-like reactions to coal mine dust as well. the generation of coal mine dust can be reduced by changes in coal cutting techniques and its dispersion can be controlled with the use of adequate ventilation and water.
Conventional mining is the oldest method. in conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. continuous mining is the most prevalent form of underground mining. in continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and.
