Coal Mining The Environmental Literacy Council
Coal is mined either through underground or surface mining. Underground mining requires digging a shaft to where the coal seam is found. The traditional room and pillar method requires leaving pillars of coal in place to help support the mine roof where miners work. Unfortunately, this method leaves more than half the coal in place.

OhioMInes Mining Artifacts
By the late 1800's, mechanization and improvement of mining methods led to a steady increase in the production of Ohio coal. Much coal was used to make coke to fuel the many steel mills that dotted the upper Ohio River valley. In 1872, Ohio mines produced more than five million tons of coal.

Underground Mining. The length of the longwall block is about 3,000 meters to 5,000 meters. In a 3 meter thick coal seam the amount of coal in place in a block is six to seven million tons. The basic equipment is a shearer (a cutting machine) mounted on a steel conveyor that moves it along the face ( Figure 37 ).

Types of Underground Mining Method Comparison
A discussion of Underground Mining also loses much of its value unless costs are considered, because the expectation of profit is the only excuse for carrying on mining at all. As conditions vary they cause fluctuations in cost and there are few operations to which a definite cost can be assigned.
