Coal Mining HouseFuel

Traditional Coal Mining. Coal was originally mined by picking lumps off where the seam came to the surface, these formed outcrops and were typically found on hillsides. These coal stocks close to the surface were quickly exhausted resulting in the ‘Bell Mine’ technique being developed. Sunken chambers were used to reach the buried material and consisted of a long shaft into the coal; from ...

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.
