Highwall mining is another surface mining form that has evolved from auger mining. A continuous miner driven by a hydraulic Pushbeam Transfer Mechanism (PTM) penetrates the coal seam. A typical cycle includes sumping (launch-pushing forward) and shearing (cutterhead boom raising and lowering to cut the entire height of the coal seam).

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. ...

Protective seam mining method is an effective way to eliminate the coal and gas outburst hazard. Auger mining (AM) is adopted to protective seam thinner than 1.0 m. The key of AM is to set intermediate coal pillar (ICP) because they have two functions: on the one hand, ICPs have to support the roof temporarily to avoid coal auger crushing; on the other hand, they have to be broken subsequently ...

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

Contour mining methods evolved to allow the economic extraction of coal using smaller and more agile equipment with more flexible mining patterns. As with area mining, it is necessary to remove the vegetation and remove the overburden to gain access to the coal seam. There are two ways to handle the removed overburden: haul it all the way down ...

High wall mining, which evolved from auger mining, is another form of surface mining. In high wall mining, the remaining part of a coal seam previously exploited by other surface-mining techniques has too much overburden to be removed but can still be profitably exploited from the side of the artificial cliff made by previous mining.
