摘要
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。
One of the root causes of the roadway supporting detbrmation even failure and rock burst is rock stress. In order to study the abutment pressure distribution of stress field in lateral Liangbaosi mine work surface, using drilling method for the mine 3108 working face drilling measurement. It has an important significance for the latter forecast rockburst risk though the field data, analyzing the distribution of surrounding rock stress field.
