摘　　要：为了研究斜沟矿地应力分布规律,采用小孔径水压致裂地应力测量方法对斜沟矿地应力进行了测试,得出了斜沟矿主应力量级、分采区主应力场类型和主应力方向,分析了地应力方向同巷道布置方位关系对后期巷道围岩变形的影响,很好的指导了井下巷道布置及支护参数选取,取得了良好效果。In order to study the stress distribution law of Xiegou Mine, the geostress of Xiegou Mine was tested by the small pore hydraulic fracturing stress measurement method. The main stress level, main stress field type and stress direction are studied. The influence of in-situ stress direction and roadway layout direction on the deformation of the roadway are analyzed, which well guides the roadway layout and support parameters selection with good results.

关 键 词：地应力 主应力 构造应力场 巷道布置 围岩变形
