The easiest way to meet the 1970 sulfur emissions regulations was to burn low-sulfur coal, which set off a dramatic expansion of low-sulfur coal mining, primarily in Wyoming.
In the West, the coal generally is crushed and sized only except for metallurgical coal. Single- and double- roll crushers are used for the initial reduction from run- of-mine to a nominal 6- to 8-inch size. A secondary crusher, often of the hammer-mill type, reduces it to less than 2 inches for shipping.

Other underground coal mines are laid out in a checkerboard of rooms and pillars Fig. 2, and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal generally 40 to 80 feet on a side left to support the mine roof. get price.
