Coal mining - Wikipedia

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 the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. In the United States, "collier…

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Tipple - Wikipedia

A tipple is a structure used at a mine to load the extracted product (e.g., coal, ores) for transport, typically into railroad hopper cars.In the United States, tipples have been frequently associated with coal mines, but they have also been used for hard rock mining.. Operation. Basic coal tipples simply load coal into railroad cars. Many tipples had simple screening equipment to sort coal ...

Coal - Structure and properties of coal | Britannica

Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and …
