This situation is even severe in Chinas large surface coal mines, in which TCS accounts for 1050 of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of commonly used mining equipment. AMay 22, 2018 Coal seam that is thinner than a certain value is defined as thin coal seams TCS.
