Abstract Based on the main gas sources of 3107 working face and the gas overrun in the upper corner, the "large diameter gas drilling extraction + fissure drilling gas extraction " was given. Through practical application, it showed that the integrated gas management technology successfully solved the technical problem of gas accumulation overrun in the upper corner, which ensured the safe and efficient recovery of the working face.
