Production system optimization is one of the effective ways to improve production efficiency.In order to prevent the problems of insufficient ventilation capacity in the north wing of the mine when it is put into pro-duction,and to solve the problem of low efficiency in removing silt coal from the central sump,the Wutongzhuang Coal Mine plans to implement an air inlet combined tunnel,and rely on the air inlet combined tunnel to realize continuous transportation of the coal cake generated by the dredging of the central water bunker purification sys-tem.After the system transformation,the air volume in the northern wing area has increased by 2 000 m3/h,and the efficiency of the purification system for transporting coal cakes has doubled.Through optimizing the system,the stability and production efficiency of mine system can be improved remarkably.
