Coal mining Coal mining Underground mining In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities.

However, longwall mining has difficulty achieving efficient production in coal seams taller than 6 meters 20 feet. This is primarily due to the fact that shearers, roof supports and other equipment large enough to mine those seams is prohibitively expensive not only because of the cost to purchase them, but because their tremendous weight.

Cost effective access to otherwise sterilised coal reserves. A fundamental principal of surface coal mining is that as the cost of uncovering the coal approaches its sales value, operations must cease in that area and move onto the next. This leaves the coal mining company with both a problem and an opportunity.
