Coal Mining Mining Operations Equipemt

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

The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used Mine rehabilitation Coal mining is only a temporary use of land so it is vital that rehabilitation of land takes place once mining operations have stopped

An underground mine consists of the portals entrance and exits to the mines mains submains panels and working faces The panels are the working sections of the production operation Depending on the mining method a working section can have one or more working faces The mining activities that

The history of coal mining goes back thousands of years It became important in the Industrial Revolution of the 19th and 20th centuries when it was primarily used to power steam engines heat buildings and generate electricity Coal mining continues as an important economic activity today

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice typically 06–10 m 2 ft 0 in–3 ft 3 in thick The longwall panel the block of coal that is being mined is typically 3–4 km 19–25 mi long and 250–400 m 820–1310 ft wide

Strip mining is the practice of mining a seam of mineral by first removing a long strip of overlying soil and rock the overburdenIt is most commonly used to mine coal and lignite brown coalStrip mining is only practical when the ore body to be excavated is relatively near the surface
