In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is necessary in order to advance knowledge of the particular geologic aspects and the extent of the coal …
What kind of underground mining is used in Illinois? In Illinois, two types of underground mining are used: room and pillar mining and longwall mining. Room and pillar mining leaves pillars, or blocks, of coal behind. Continuous-mining machines are used to remove the coal. As the machine breaks the coal, large arms gather the coal on a conveyor belt.

Conveyor - An apparatus for moving material from one point to another in a continuous fashion.
Room-and-pillar mining in low seams is generally less efficient than longwall mining because as much as 50% of coal is lost. There are two main longwall extraction systems: shearer and plow. Both systems have been used in the German underground hard coal mining industry for many years. In past decades, there were periods of dominance for …
