Coal extraction method –surface, deep underground mining ...

Underground mining: Coal at a depth of 180 to 300 ft (50 to 100 m) is deep mined, however in some cases the technique of surface mining are implemented. Underground mining is undergone when the coal is present at the depth of 180 to 350 feet. Room and pillar mining and longwall mining are the two types of underground mining.

An Introduction To Surface Mining

Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world's commerce and production. Mining could be classified in two forms: mining at the earth's surface (surface mining) and mining underground (subsurface mining).

A Brief Introduction to the Types of Surface Mining ...

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 ...

Surface mining - Wikipedia

Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as overburden removal.It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface and/or is mostly horizontal.
