摘 要:本文通过数值模拟及现场矿压观测,分析采空侧对巷道围岩塑性区分布、煤壁破坏深度及煤体位移的影响,结合矿压测站的数据,对采空区侧巷道超前支承压力影响范围、压力大小、增幅及压力峰值进行分析,对工作面超前支护进行合理推算,确保巷道围岩的稳定。Based on numerical simulation and on-site mine pressure observation,the article analyzes the influence of gob side on the plastic zone distribution of the surrounding rock of the roadway,the depth of coal wall damage and the displacement of the coal body.Combining the data from the mine pressure measurement station,the article analyzes the influence range,pressure magnitude,increase and pressure peak of the advanced support pressure of the side roadway in the goaf,and makes a reasonable calculation of the advanced support of the working face,which ensures the stability of the surrounding rock of the roadway.
