Shaft: Site Selection, Shape, Depth Pillar Deep

The deepest shaft in coal mine in this country (600 m depth) is at Chinakuri Colliery. Shaft Pillar: Since the inclines and shafts serve as means of access to underground mines throughout their life they should be in strata which are not likely to subside or collapse. In a mine a solid block of rock known as shaft pillar should be kept on all sides of the shaft, and only essential rods should ...
