摘要
Abstract
In the air inlet roadway of 3121 working face of Yongming Coal Mine,the roof and floor displacement,hydraulic support force and other mine pressure parameters of the air inlet roadway are monitored,and numerical model simulation is carried out according to the gas situation of the working face.The monitoring results show that the deformation of roof and floor is effectively controlled and the deformation of surrounding rock is obviously reduced,which can effectively avoid the problem of mine pressure behavior and the large-area deformation and crushing of roof.The simulation results show that after the gob-side entry retaining,the gas concentration near the working face decreases,more gas is discharged from the goaf,and the problem of gas accumulation in the upper corner is improved.关键词
