The coal is usually cut via a continuous miner that delivers the product to hollers. The product is brought to feed a breaker unit and to prepare and deliver it onto the belt system. Feeder breakers are moved only once in a while; however, the other equipment is in constant motion in order for the maneuverability cable to be operational and the ...
blasting is almost exclusively employed to cut prismatic blocks or tabular slabs of rock. The high labor intensity and cost associated with cutting stone makes quarrying the most expensive surface mining method. Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden.

Mechanization of West ia's coal mines took place gradually throughout the first half of the 20th century. Traditionally, coal mining involved the distinct steps of undercutting the seam, then drilling and blasting the undercut coal into manageable pieces, and finally loading and hauling the coal to the surface. The complexity of these tasks and the tight spaces encountered underground ...
After the merger with Monighan in 1946, Bucyrus began producing much larger machines using the Monighan walking mechanism such as the 800 ton 650-B which used a 15-yard bucket. Bucyrus' largest dragline was Big Muskie built for the Ohio Coal Company in 1969. This machine featured a 220-yard bucket on a 450-foot boom and weighed 14,500 tons.
