Application of highwall mining system in weak

29-04-2016  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.

Application of Highwall Mining System to Recover

01-01-2013  Abstract. At open pit coal mines, a large amount of coal is left around the end-walls due to the stability of slope, mining boundary, and so on. In order to increase coal recovery of open pit coal mines,the application of a highwall mining system for residual coal around the end-walls is proposed. This mining method can be extracted the coals ...
