Auger mining coal mining Britannica

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

A Method To Eliminate Explosion Hazards in Auger Highwall

The auger highwall mining method is an effective meth- od to recover coal from a reserve when removal of the overburden by surface mining equipment becomes uneco- nomical. In this method of mining, a horizontal auger enters the coal seam from the surface mine bench under the highwall and the coal is literally drilled in a series of

For Surface Mines And Auger Mines

Surface Mining 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.
