摘　　要：随着矿井开采深度的增加,地应力对围岩变形与破坏的影响更加突出,在煤矿矿区进行地应力测量,并分析地应力场分布规律具有重要意义。在旗山煤矿-1000 m和-850 m深度利用应力解除法进行了地应力实测,数据分析表明：旗山矿区深部地应力场以水平应力为主,构造应力占绝对优势,属于典型的构造应力场类型;地应力量级属于超高地应力;最大主应力方向为NW-SE向121°~140°,平均为130°。最后结合构造运动进一步探讨了矿区深部地应力场与地质构造的关系。With the increasing of coal mining depth and intensity, the geostress plays more important roles in the displacement and damage of surrounding rock. It is very important to take geostress measurements and ana- lyze the distribution characteristics of the geostress fields in coal mining area. The geostress measurements have been conducted within the depths of - 1000 and - 850 m in Qishan Coal Mine by using stress relief method. The analysis of the measurement data indicates that： The geostress field in Qishan Coal Mine, in which the tectonic stress takes absolute predominance, is dominated by horizontal stress and belongs to typical tectonic stress field;The magnitudes of the geostress are super high stress level. The orientations of the maxi- mum horizontal principal stresses mainly concentrate on NW - SE121° - 140°, the average is 130 . Finally, combined with the tectonic movement to further explore the relationship between mining deep geostress field and geological structure.
