Appendix E: Coal Mining and Processing Methods Coal ...

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 ...

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

A Brief Introduction to the Types of Surface Mining Methods

Open-pit Mining. Open-pit mining is a method in which an ore is removed by digging a pit in the ground, and is used to remove copper, gold, iron, as well as non-metallic minerals. It is normally used when the rock layer above the ore is too weak to allow underground tunnels. In this technique, circular steps, or ‘benches’, are dug around ...
