以构造与地应力的耦合关系为核心,分析了赵楼井田矿井构造的分布规律和形成演化模式,应用水压致裂法和应力解除法实测了井田地应力的大小和方位,对井田内地应力场的分布特征、主要影响因素、构造控制下的地应力场变化规律、构造与地应力场的耦合关系等进行了研究.结果表明:构造演化模式控制了矿井构造的发育规律;研究区以水平应力为主导,最大水平主应力的方向为NE65°~87°,最大、最小主应力差值较小;矿井构造特征控制了井田地应力场的分布格局,造成了主应力大小和方向的变化,同时,地应力场对矿井构造演化又具有促进作用.
Based on the coupling relationship between tectonic stress and geostress, the distribution and evolvement mode of mine structure in Zhaolou mine field are analyzed. The size and azimuth of geo-stress in mine field are measured by hydraulic fracturing method and stress relieving method. The distribution characteristics of the field, the main influencing factors, the variation law of the geostress field under the tectonic control and the coupling relation between tectonics and the geostress field.The results show that the tectonic evolution mode controls the development law of the mine structure, Stress is dominant, the direction of the maximum horizontal principal stress is NE65 ° ~87 °, and the difference between the maximum and minimum principal stress is small. The mine structural features control the distribution pattern of the field stress field and cause the change of principal stress magnitude and direction, At the same time, the geostress field can promote the tectonic evolution of the mine.
