Abstract. A coal-mining auger having a a hollow, tubular auger head with a spiral or helical coal conveyor mounted therein in concentric relation to the axis of rotation of said auger head, b a plurality of coal-cutting bits mounted on said auger head, said bits being orbitally movable with the auger head in circular paths concentric with said axis of rotation, said bits being also ...
Underground testing began in August 1981 at Peabody Coal Companys Marissa Mine near Marissa, Illinois. The auger was developed to increase mine production and coal recovery without increasing land subsidence. It bored 4-foot-diameter by 10-foot-deep holes into pillars on 7-foot centers each hole recovering 5 tons.

Underground coal mining and surface mining of other minerals depend on high-quality augers. Since the mid 1950s, augers have been an integral aspect of both underground and surface mining. At Falcon Industries, we take great pride in providing custom built augers that the mining industry requires to complete its operations efficiently and safely. In addition to Falcons augers being used in the mining of products, mining
Auger mining, method for recovering coal by boring into a coal seam at the base of strata exposed by excavation. Normally one of the lowest-cost techniques of mining, it is limited to horizontal or slightly pitched seams that have been exposed by geologic erosion. Augering is usually associated with contour strip-mining, recovering coal for a limited depth beyond the point where stripping becomes uneconomical because the seam of coal
Auger mining operations drill a series of parallel holes perpendicular to the highwall, leaving adequately sized pillars between holes to maintain the stability of the highwall and overlying surface area. The technique is also commonly used to recover coal beneath surface features which limit surface mining, such as rivers and roads.

Dec 14, 2010 Auger mining was introduced to the West Virginia coalfields in the 1940s. Today, auger mining continues to be used as a surface mining method in West Virginia, usually on contour surface mines where augers drill the last available coal from the highwall. A recent offshoot of auger mining is the development of highwall miners.
