Coal is the main energy source in China, and the continuous innovation of coal mining theory, technology and equipment had supported the rapid development of China's coal industry. Compared to 1978, China's raw coal output had increased from 0.62 billion tons to 3.68 billion tons, death rate per million tons of coal mines had decreased from ...
Dec 11, 2018· Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 50-80 meters of the surface. The job of a miner primarily involves removing 'overburden'— rock, soil, trees etc. – that mix with the coal deposits and cover them near the earth's surface.
