'Coal' and 'China' to some extent have become synonymous. China is by far the largest user of coal in the world. In 2016, coal production in China amounted to 3.21 billion tons, about half of the total global coal production. Coal consumption accounts for more than 65% of primary energy consumption in China. The Chinese coal industry greatly …

Coal seam that is thinner than a certain value is defined as thin coal seams (TCS). It commonly occurs in China as it covers 84.2% of the mining area. This situation is even severe in China's large surface coal mines, in which TCS accounts for 10–50% of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of …
