The MSHA District will receive and acknowledge that an appropriate highwall/ground control plan conforms to the requirements of 30 C.F.R. § 77.1000. MSHA should make sure that all auger holes/highwall entries are properly closed or blocked, in accordance with 30 C.F.R. § 77.1505 at the abandoned areas.

Highwall mining is a hybrid of surface mining and underground mining methods, and is often the only feasible method to recover the coal reserves in the central Appalachian coalfields due to the steep terrain and the closely spaced multiple thin coal seams.

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.

High Wall Stabilisation. Specialised GEO installs a wide range of stabilisation solutions suitable for high wall and auger mining environments. Our highly experienced technicians are trained in the latest techniques for high wall stabilisation to protect mining infrastructure and personnel with a proven track record of safety and reliability.

Highwall mining is an important surface coal mining method, and it may account for approximately 4% of total U.S. coal production. Highwall stability is the major ground control related safety concern. Ground control plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes ...

Team Building. All associated reporting requirements. Very enjoyable time working with a small team of 8 energetic men.

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.

§ 45.2-936. (Effective October 1, 2021) Highwall inspections. A. A mine foreman shall inspect the face of each highwall for a distance of 25 feet in both directions from an auger or highwall miner operation (i) before any such operation begins and at least once during each coal producing shift and (ii) frequently during any period of heavy rainfall or intermittent freezing and thawing.

highwall mining technology. A detailed case study on a panel failure is also presented. Keywords: Highwall mining, panel stability, pillar, span. 1. Introduction Highwall mining is a remotely controlled mining method which extracts coal from the base of an exposed highwall, typically via a series of parallel entries driven to a

The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

The success of high wall mining operations depends significantly on geological features, notably the stability of the working roof, determined by the type and mechanical properties of the immediate roof strata. Stability of the ribs, absence of floor heave, faults and dykes are further important prerequisites for profitable highwall mining.

The Highwall Pump is designed to have the main frame / power pack situated on top. of the highwall edge, with the wet-end lowered over the pit wall and into the water. accumulation on the pit floor. The advantages of this pump format over conventional pit type pumps are: Quick mobilization and demobilization with minimum labour requirements.

Highwall mining, in particular, has come a long way, and modern mining operations are reaping the benefits with new mining solutions. Traditionally, highwall mining information gathering primarily took place on foot, with geologists and geotechnical engineers walking up to the wall and conducting field research by hand.

Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in
