Highwall Miners Selection Guide: Types, Features

Highwall mining has advantages compared to underground mining, such as a higher level of safety due to the use of remote controlled cutterheads. Highwall mining also requires a relatively small crew of three or four people. Operation. Highwall miners extract coal from exposed seams by driving a cutter module into a coal seam under a highwall. The highwall mining

Ground Control Design For Highwall Mining

The highwall mining equipment dictates the hole width which varies from 2.7 to 3.6 m (9 to 12 ft). In situ vertical stress depends on the overlying rock density and overburden depth. Vertical stress gradient is typically 0.025 MPa/m (1.1 psi/ft). Overburden depth may be taken as the maximum overburden depth on a highwall mining web pillar, which is very conservative, or alternatively as a high

Analysis of Highwall Mining Stability The Effect of

Auger and highwall mining are safe and productive surface coal mining methods provided that proper geotechnical engineering is conducted. Failure to properly engineer web and barrier pillars can result in highwall failure, trapped highwall mining equipment, and significant economic impact as most of the equipment lies under the highwall. These

Position Sensing Hydraulics In Highwall Mining Equipment

25/07/2017 To drill directly into the “high walls” left by surface mining in an economic way, requires specialized equipment. Highwall mining is actually a hybrid of surface and underground mining technologies. It is a people-free, low footprint mining process which uses high power hydraulic cylinders as part of a Pushbeam Transfer System. In this system, high power hydraulic cylinders advance the

Design Programs for Highwall Mining Operations

highwall mining will be a dominant method for extracting the high-value coal resources in the Appalachian coalfields. By far, the greatest ground control safety concerns in highwall mining operations are rock falls from the highwall and mining equipment entrapment underground. These hazards are most likely caused by the instability of the highwall mine system due to insufficient mine design
