| 摘 要： | 以淮南潘—矿为工程背景，依据地质动力区划方法。进行Ⅰ～Ⅴ级活动断裂的划分，确定区域构造形式，研究了C13-1煤层构造格架、主要断裂特点，在此基础上，建立了构造应力场的地质模型，结合地应力测量和岩体应力分析，确定区域岩体应力分布规律。其结果表明，煤矿区域原岩应力分布状态主要受断裂构造的支配，断裂构造的叠加扰动使原岩应力场重新分布，从而在时间和空间上制约若潘—矿煤与轧斯突出的区域性分布，为安全生产提供保障。

| Abstract: | Taking Panyi mine of Huainan as engineering background of the research,I~V class active faults are divided and certain local geology structure is determined according to geo-dynamic division.The structural pattern and the features of main faults in C13-1 coal seam are studied.Then,the geological model of tectonic stress field is built.Incorporated with the surveying of geo-stress and rock stress analysis,the feature of rock regional stress can be found.The result indicates that the distribution of regional initial rock stress of mine depends upon the faults and is formed again because of superposition of the action of faults.Therefore,the regional distribution of coal and gas outbursts in Panyi mine are controlled by it from time to space,which can ensure safe production. |
