  • Shaft Sinkingan overview ScienceDirect Topics

    This process known as in situ or underground gasification typically involves drilling boreholes or sinking shafts to intersect the seam in at least two places and providing a passage for gas through the seam from one intersection to the other using such techniques as cross-drilling hydraulic fracturing explosive rock breakage or underground mining methods. The coal can also be ignited at the base of one borehole

  • Selection of Shaft Sinking Method for Underground Mining

    In this paper our concern is about shaft sinking method for underground mining. Depths of the coal seams reveal the necessity of a vertical shaft underground which again needs deep excavation. The problem arises with the excavation because of nearly 138m thick Dupitila Sandstone Formation just 6m below the surface in the area.
