HIGH WALL MINING IN SCCL SCCL entered in to agreement with M/s Advanced Mining Technologies to extract about 6 million tonnes of coal from four OC mines in a span of 6 years. Availability of high wall face is the main requirement for continuous working of this technology and there is potential in SCCL to meet this requirement. 5.

Highwall Mining Evolves. From the bridge of the highwall miner, an operator advances a cutterhead, or an unmanned cutter module, into an exposed coal seam. The machine rests on crawler tracks on the bench below the highwall. Coal is extracted in parallel rectangular (the width of the cutterhead) entries spaced at various intervals.

When the conditions are just right - you're hard pressed to find a better coal mining machine than a highwall miner. This video shares the key features and ...

7.3.3: Auger Mining. Earlier in this lesson, you saw the highwall that remains after the ultimate pit limit is reached in a contour mining operation. At that time, I pointed out the possibility of recovering the coal under the highwall, by either developing an underground mine or highwall mining. The former is rarely economically feasible today ...

Highwall mining is a hybrid of surface and underground mining technologies that is used to recover coal that is otherwise uneconomical due to: Increasing open – cut strip ratios Reaching pit limits with available coal in the barrier pillars Protected surface features (e.g. rivers, streams, archaeology) Inadequate panel length for a punch long wall Mining […]

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 ...
