High Wall Mining Technology• Highwall Mining is a remotely controlled mining method, which extracts coal from the face of a coal seam under a highwall in a surface mine, which has reached the final highwall position due to uneconomic stripping ratios Or due to local constraints which limit further surface mining.• The coal left in the High wall can be extracted by this technology which otherwise …
Highwall Concerns - Mining Technology | Mining …
04.09.2015 · As mining advances and mine design standards undergo operational changes, it is crucial any geotechnical assumptions be reviewed and modified by an experienced engineer or geologist to continuously ensure the integrity of the final highwall design and reduce the likelihood of highwall instability and rock-fall hazards.
Coal Augering Services - Mining Technology | …
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.

03.04.2019 · Highwall mining (HWM) technology is an efficient method for exploiting residual coal resources in Chinese open-pit coal mines. However, on-site personnel and equipment can be damaged by the instability of the highwall mining residual coal pillars and subsidence of final end-walls. This stone considers the geological conditions of an open-pit mine in Shendong Coal Field (China) in …
Application of highwall mining system in weak …
29.04.2016 · In its basic application, highwall mining is a technique utilized after the open cut portion of a reserve has been mined, sometimes prior to the introduction of underground mining (Seib 1993). In these mining systems, a continuous miner or an auger machine is primarily used to extract coal from the highwalls.
