How is coal formed?Coal is known as black gold, the food industry, it is one of the main energy use of the human world since eighteenth Century. Although its important position has been replaced by oil, but in the future for a long period of time, due to the exhaustion of petroleum, inevitable decline, but because of the huge reserves of coal, and the rapid development of science and technology, the new technology of coal gasification is becoming more mature and widely used, coal will become one of the production and life of human beings in an irreplaceable energy.Coal is millions of years of plant leaves and roots, stacked on the ground with a layer of very thick black humus, due to changes in the earth's crust constantly buried underground, long isolated from the air and under high temperature and pressure, after a series of complex physical and chemical changes and other factors, the formation of black however, this fossil, is the coal forming process.The thickness of coal seam in a coal mine and the crust drop speed and accumulation amount of plant remains. The crust decreased rapidly, the plant remains piled thick, the coal seam is thick, on the other hand, the crust decline slowly, the accumulation of plant remains thin, the mine coal seam is thin. The tectonic movement of the crust to the original level of coal seam folds and faults occur, some underground coal seam buried deeper, and squeezed to the surface, even above the ground, more likely to be found. There are some relatively thin coal seam, and the area is not large, so there is no value related to the formation of coal mining, so far not find the update statement.
