• Highwall Mining System e-library WCL

    Highwall mining is a proven primary method for mining coal from outcropping horizontal seams. In this method of mining, an unmanned continuous miner is driven underground and operated in front of the highwall.

  • Highwall Trench Mining as a Primary Production Method of

    Oaky Creek Coal (OCC) has embarked on an ambitious program to fast track the introduction of Trench Mining into its current mining operations. The project has the capacity to allow the extraction of reserves at stripping ratios, uneconomical by conventional mining methods. Trench mining using Continuous Highwall Mining (CHM) technology reduces the in-situ stripping ratio.

  • Highwall Trench Mining Research: Implications for Mine

    Results from current NERDDC funded research into the geotechnology of highwall trench mining methods have clear implications for mine planners in the areas of blast design, trench shape, location of the surcharge spoil and remnant coal pillar design. Adoption of successful smooth wall blasting techniques not only removes safety hazards from the trench face, but.
