Abstract: | Abstract Based on Guanwen coal mine, the multiple coal seams with low permeability and strong outburst dangerous, that gas extraction solution design thorough studied. Extraction scheme mainly includes: protective mining area gets bedding drilling pumping and adjacent layer discharging pressure gas, goaf gas extraction, backplane wear layer represents coal roadway channel drilling smoke gas and coal roadway heading face while digging and extracting. |
