Coal Mining 101 The Coal Seam

The typical method of assessing surface mining economics for a coal seam is a calculation of overburden (native rock and soil above a coal seam) moved per clean ton of coal produced, commonly referred to as “mining ratio”. The higher the mining ratio (or more overburden moved per clean coal ton), the higher the cost of producing coal.

Equipment underground COAL

Machine position or attitude is usually measured relative to other parts of the machine itself, to other equipment or the position in space. In fact what is usually required is the position relative to the coal seam as that is what has to be followed (though in some instances even this is not desirable eg sudden changes cannot be followed)

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
