Feasibility study and optimal coal drawing process for fully mechanized caving in close-distance extra-thick coal seams

Research on optimal coal drawing parameters for working faces with significant variation in seam thickness, where the thickness exceeds the standard mining height in close-distance coal seams, has been limited. This study focused on the feasibility and optimal coal drawing process for fully mechaniz...
