摘要
Abstract
Based on the numerical simulation method,the influence of mining disturbance on the upper and lower stages of off-vein roadway is analyzed.According to the analysis of the simulation results,the influence of mining disturbance on the roadway mainly occurs in the roof and floor.The mine should strengthen the support of the roof to prevent the occurrence of safety accidents.With the progress of mining,the tensile failure mainly occurs in the top and bottom and increases continuously.Comparing the-380m roadway with the-420m roadway,it can be seen that the damage to the-380m roadway is great in the mining process.The mine should comprehensively consider the actual situation of the roadway and the service situation,and carry out targeted secondary support operations.关键词
