The choice of an underground mining method depends on a range of factors and these include; the size and shape of the deposit, the orientation or slope of the deposit, the depth of the deposit, geological structures, characteristics of the ore and the surrounding rocks and issues with gas and water. In combination, these factors allow us to determine an appropriate arrangement and sequence for ...
Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.
Drilling equipment currently accounts for the highest revenue amongst all equipment in the underground mining market, and is predicted to dominate the market throughout the forecast period. Drilling equipment is projected to be valued at a profitable revenue of ~ US$ 7 billion by 2027, in the underground mining market.
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined.

In most underground mining methods, deep vertical tunnels called shafts are drilled into the ground, along with a set of horizontal tunnels called drifts from the shaft bottom to access the ore. Then, longwall and continuous miners break up the ore deposit, which is transported back to the surface by conveyors.
the mining technologies currently in use on Federal leases and the potential for commer-cial mining technologies to extract Federal coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in
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.
