Commonly used mining techniques to extract coal IEA
Jan 25, 2018· As mining of coal depends on the depth and quality of the coal seams, different techniques are used to dig the deposits. Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction.
