【摘要】 为了保证山东万福煤矿矿井建设和开采的安全,在前期勘探阶段即采用水压致裂法进行了矿区地应力场测量.分析了矿区的区域地质构造与现今构造运动特征、地震活动性及区域构造应力场,以及根据实测结果获得的矿区地应力场分布规律,确立了矿区实测地应力场与区域地质构造的一致性关系.更多还原

【Abstract】 In order to ensure safety of capital construction and mining operation in Wanfu Coal Mine,in-situ stress measurement with hydraulic fracturing technique was carried out in the early exploration stage.The characteristics of regional geological structures and tectonic movements,as well as the earthquake activities and regional tectonic stress field were analyzed.Based on results of hydraulic fracturing measurement,the distribution law of in-situ stress field in Wanfu Coal Mine was obtained.Through comparison analysis,the distribution law of in-situ stress field obtained by the practical measurement shows good agreement with the regional tectonic stress field.更多还原
