What Is the Environmental Impact of Mining and Burning Coal?

Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming. Subsurface coal mining is dangerous. Coal is often mined in subsurface mines, which may collapse and trap miners.

Coal Coke Analysis & Testing at Standard Laboratories

Coal Coke Analysis and Testing. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. Coking coal must also have low sulphur and phosphorous contents.

Volatile Matter (Part of Proximate Analysis), Coal

Volatile matter is directly related to coal rank; as rank increases, volatile matter content decreases (Stach and others, 1982). Volatile matter has the opposite trend of fixed carbon with rank. As volatile matter is driven from the coal matrix with increasing rank, the relative carbon percentage tends to increase.
