Also, the explosive methane-air mixtures with between 5 and 15 methane. A combustible gas formed in mines by decomposition of coal or other carbonaceous matter, and that consists chiefly of methane. Fissure - An extensive crack, break, or fracture in the rocks.
It was mainly composed of methane, like the natural gas that we use for cooking and heating today. If a miner came into contact with fire-damp underground, the flame of his candle would sometimes cause the gas to explode.

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 called a 'pit.
