Abstract In order to solve the gas management problem of high gas comprehensive mining face, the gas source was analyzed, and a comprehensive management scheme of "partial W ventilation + face oblique cross borehole pumping" was proposed, the calculation results showed that the ventilation resistance of partial W ventilation was only 41% of that of U ventilation, and the simulation results showed that partial W ventilation can effectively solve the problem of gas concentration over limit at the upper corner.
