2020-3-12 · 4. Open cast mining. Also known as open pit mining, this is a method of surface mining where a large pit is made in the ground, and the coal is mined directly from that pit. This is a great method to use for a shallow coal seam and it is extremely productive. Of all the types of mining, this is one of the safest processes.

Auger mining is a relatively low cost method of coal mining and is practical in areas where the overburden (material covering the coal seam ) is too thick to be removed economically or wh ere the

Coal Mining

2019-2-25 · Coal Mining. Types of Coal Mines. There are four main types of coal mines: shaft mine, slope mine, drift mine, and surface (open-cast) mine. The mine at Coalwood was a shaft mine; the coal was brought up in an elevator from 600 to 800 feet underground. The University of Kentucky has an interesting diagram showing each of the four types of mining.

Types of Coal Mining

When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is …

Coal – Types, Uses and Formation

It is cheaper than underground coal mining. There are three types of surface mining - strip mining, where explosives are used to remove the top layers; open pit mining when a pit is dug, and MTR mining where a whole mountain summit is destroyed. Underground mining is performed when the coal is deeper than 300ft below ground level.
