Open pit mining is undertaken for coal deposits relatively near the surface, e.g., 20 m, while deeper deposits may necessitate underground mining activities [6]. Over 90% of the mining activities in developed economies adopt open pit methods [6].

Project location:Application of highwall mining system in weak ,2016-4-29 · Almost all the coal is produced from open cut mines in Indonesia. As a consequence of open cut mine application, a great deal of coal is left out in the highwalls of the mined-out pits. Highwall mining systems can be used to recover this coal. The use of highwall mining systems has increasingly come into play in the US and Australia. However, it is not common in Indonesia.

  • Geotechnical Issues on Application of Highwall Mining

    2015-3-20 · 2. Highwall Mining Systems Many coal seams that are presently uneconomical or technically unsuitable for conventional surface mining techniques can be recovered using highwallmining systems. Final highwalls of open cut coal mines can form the starting point for other mining methods, such as highwall or underground mining.Highwall Stability due to Punch Mining at Opencut ,2018-6-16 · Conventional highwall mining extracts coal with an auger machine or a continuous miner from exposed seams at the base of opencut or strip operations. However, under poor strata and high stress conditions, highwall mining cannot be conducted due to pillar and roof failures. In such cases, punch highwall mining is more effective than the conventional highwall mining.
