Underground Mining Transportation & Haulage Systems

In an earlier Bureau of Mines publication it was pointed out that the cost of underground transportation constitutes a considerable percentage of the total mining cost in most mines, and in some mines may even exceed the cost of stoping. At 19 open-stope mines, transportation averaged 26.3 percent of the total underground cost; at 19 mines

Coal mining Underground mining Britannica

Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities

Coal mining Wikipedia

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which
