围岩应力是引起巷道围岩支护变形与破坏、产生冲击地压等现象的根本原因之一。为了研究梁宝寺矿井工作面侧向支承压力内应力场的分布,采用钻屑法对矿井内3108工作面进行钻屑法测量。通过现场实测数据,分析围岩应力场的分布,对后期预测冲击地压的危险性具有重要意义。
Surrounding rock stress is caused by roadway surrounding rock deformation and damage, resulting in the impact of ground pressure and other phenomena one of the fundamental reasons. In order to study the distribution of stress field inside the lateral bearing pressure of the working face of Liangbaoji Mine, drilling cuttings method was used to measure the drilling cuttings of 3108 working face in the mine. It is of great significance to predict the distribution of stress fields in surrounding rock through predicting the risk of rockburst in the later stage.
