Types of Coal Underground Mines

A mine opening is made by sinking a shaft down to the elevation of the coal seam. Mining is conducted using typically either longwall mining or room and pillar mining with continuous mining equipment. Coal is transported to the surface by a skip hoist. This is the most expensive type of underground mine to build and operate. Get price

Identification of safety hazards in Indian underground

Jan 01, 2018Most of the underground coal mines are either mechanised or semi-mechanised. The types of machinery commonly used in underground coal mines are load-haul-dumpers, side-discharge-loaders, universal drill machines, handheld drill machines, rope haulage, conveyors, ventilation fans, dewatering pumps, shuttle cars and locomotives .

How Underground Mining Works

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Access drifts

They are typically driven parallel to the strike of an orebody (dependent on mining method and orebody shape) and see the heaviest traffic in a mining operation out of all areas on a level. [3] A rule of thumb for the placement of these drifts is at least 15 m away from ore in good ground, or one stope length, whichever is greater. Get price

Engineering Essentials: Fundamentals of Hydraulic Pumps

This is accomplished through a single load-sensing signal originating from the priority circuit and routed as close as possible to the discharge side of the pump's gears. Adding an unloader control to the pump circuit, Figure 20, allows the system to conserve power in the standby mode of operation as well as in the running mode. Get price
