The Thin Coal Seam (TCS) Mining Technology for
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 commonly used mining equipment.

Justification of Open Pit Mining Technology for Flat
The article describes a problem of considering the coal strata bedding for the scheming of dragline mining technology for open pits developing flat seams. For three flat coal seams strata processing the main criterion defining the choice of technology of their processing is the stratigraphic positioning rate for the middle coal seam. It is the ratio of the upper and lower interbeds height.
