摘要
Abstract
In order to solve the problem of serious advance deformation of roadway in lower coal seam working face during the mining process of island working face in close distance coal seam,Shanxi Lingshi Huayuan Coal Industry by analyzing the source of pressure,the dynamic pressure stress superposition of coal pillar,thick and hard roof and mining disturbance in upper coal seam mining led to serious advance deformation of roadway in lower coal seam.According to the analysis results,the control method of advanced roof cutting and pressure relief was put forward.The advance blasting pre-splitting was carried out in the upper coal seam mining roadway in advance to reduce the pressure influence of the lower coal seam mining roadway,so that the deformation of the roadway was reduced from the maximum 2.4 m to the maximum 0.8 m,which ensured the safety production of the working face.关键词
