Abstract：Shuomei Wangping Coal Mine is a gas-containing mine shaft,its 4301 working face adopts the"air exhaust"method to control gas,and the ventilation system is a"two into two back"type.In the actual operation,it was found that there were still problems of gas concentration exceeding the limit during mining,and the management and maintenance of the ventilation system was difficult,which affected the efficient implementation of mining operations.Based on the above problems and combined with the actual situation of the working face,a scheme of synergistic governance of air ex-haust and extraction was proposed,and the ventilation system was adjusted to the"two-in-one"type.Through the theoretical calculation of gas emission in the working face and the simulation analysis of the law of gas migration in the goaf,the synergistic governance scheme was designed and applied in practice.The results show that after the synergistic governance scheme of"two-in-one"ventilation system and high pumping roadway is adopted,the air distribution volume of the working face ventila-tion system is reduced,but the gas of the working face is fully controlled,and the maintenance diffi-culty of the working face roadway is reduced.
