underground coal mining in india vertical shaft
Theory I Sub: - Underground Coal Mining Chapter Shaft
The strata through which a shaft has to be sunk may be divided into three groups. i) Sub –soil or alluvium ii) Hard rock below the alluvium and above the mineral bed (generally consisting of sand stone, shale, thin coal seams, etc. in coal mining areas) iii) The coal seam or the mineral bed.

Excavation Methods - Vertical Shafts - underground COAL
Vertical Shafts. There are 4 methods in general use: Conventional drill, blast & remove stone ("muck out") to surface with a winder. If the shaft is to be "lined" (i.e. sides to be covered with a concrete or even a steel lining), this is normally placed as the shaft is excavated. Drill a pilot borehole from surface to existing underground ...
