No. 3 coal seam of Sima Mining Industry Corporation Ltd., Lu’an Group was single thick coal seam, with poor permeability. Combined with the fracture zone borehole extraction from the measured data, fracture zone drilling hole arrangement, final hole horizon parameters and working face advancing influencing extraction effect were studied and analyzed, which provided certain reference value for same typed coal seam stoping gas extraction.
