Underground Mining - JA Engineering

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.

Coal Mining 101 | The Coal Seam

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and ...

Coal mining - Choosing a mining method | Britannica

Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.

Underground Coal Mining - Pennsylvania DEP

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 ...
