Auger - Less common in recent years, auger mining is sometimes employed to recover any additional coal left in deep overburden areas that cannot be reached economically by further contour or area mining. An auger functions much like a wood drill, to bore into the seam and discharge coal out of the spiral onto a waiting conveyor belt.
Jul 03, 2015 7.3.4: Highwall Mining. Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more sophisticated machine, known as a highwall miner. The highwall miner shares some common elements with a continuous mining machine.
The auger bit is 30 inches in diameter and uses 6-foot long auger sections. During a normal mining cycle, auger holes can be drilled 400 to 500 feet deep. The holes are drilled side by side, with about 15 inches of support coal between them. The most recent auger mining at the 001 pit was one month before the accident.
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.
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

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Mar 30, 2017 The coal seam was originally auger mined in the late 1980’s. At the time of the accident, the Green Hill Mining, Inc.,GHM #51 was operating with the permission of the surface mine operator, Alden Resources, LLC. Green Hill Mining’s intent was to auger mine through the existing auger entries of the coal seam.
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.
