· Coal mining Coal mining Coal deposits: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and

Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth''s surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.

Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio''s bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery.

Equipment Cutting Machines Introduction. There have been several different types of cutting machine developed over the years, but "shearers" and "ploughs" have proved to be the most successful, especially the former and will be the only types dealt with in any detail here. Some types, such as "trepanners" were designed to produce a larger size of coal required for boilers, particularly for

Coalcutting machines can operate in gently sloping, sloped, and steep seams. The first attempt to mechanize coal cutting was made in Great Britain in 1761, when M. Menzies received a patent for a mechanical cutting device in the form of an iron miner''s hack, mounted on a frame and driven by rods and levers from the surface of the shaft.

Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines
