Coal-mining technology in China ScienceDirect

Although China is the second largest coal-producing country in the world, the geological conditions of the country's coal seams are not always favorable. The coal seams in most of the existing coal-mining areas are to deep for surface mining. Therefore, about 96% of China's total coal production is from underground mines. Since the early 1950s great efforts have been made to improve coal

The Estimation of the Number of Underground Coal

The number of underground coal miner, collective dose and normalization collective dose are estimated at present base on surveying annual output and production efficiency of raw coal in 2005-2014. The typical total value of the underground coal miners recommended in China is 5.1 million in 2005-2009, and in which there are respectively included 1 million, 0.9 million and 3.2 million for NKCM

Coal Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
