Coal Mining Equipment In China

Coal Mining

The goal of coal mining is to remove coal from the ground. Coal is valued for its energy content, and since the 1880s is 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 States, United Kingdom, and South Africa, a coal mine and its structures are a "colliery". In Australia, "colliery" generally refers to an underground coal mine.

Coal Mining Industry

The Industrial Revolution, which began in Britain in the 18th century, and later spread to continental Europe and North America, was based on the availability of coal to power steam engines. International trade expanded exponentially when coal-fed steam engines were built for the railways and steamships. The new mines that grew up in the 19th century depended on men and children to work long hours in often dangerous working conditions.
The oldest continuously worked deep-mine in the United Kingdom is Tower Colliery in South Wales valleys in the heart of the South Wales coalfield. This colliery was developed in 1805, and its miners bought it out at the end of the 20th century, to prevent it from being closed. Tower Colliery was finally closed on 25 January 2008, although production continues at the Aberpergwym drift mine nearby.
Coal was mined in America in the early 18th century, and commercial mining started around 1730 in Midlothian, Virginia.
Coal-cutting machines were invented in the 1880s. Before the invention, coal was mined from underground with a pick and shovel. By 1912 surface mining was conducted with steam shovels designed for coal mining.

Coal Mining Equipment

Coal can be a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams .Coal is primarily used being a solid fuel to produce electricity and also heat through combustion. people usually crush the more expensive coal block to small one by coal crushing plant, use coal mill or coal pulverizer to grind the coal.
