华北地区构造应力场非均匀特征与煤田深部应力状态
|
摘要
将华北地区分成11个应力小区,依据华北地区近期1111条中小地震震源机制解数据,利用格点尝试法分析华北地区主应力方向的分布特征,结果显示,华北地区现今构造应力场以水平作用为主,其中,唐山和晋南地区最大主应力方向为近EW向,其他地区最大主应力方向均为NEE向,方位为NE60°～80°。鲁西南万福煤矿深部水压致裂原地应力测试结果显示,水平最大主应力方向的为NE40°～80°,与鲁西南地区中小地震震源机制解的分析结果十分接近。通过构造类比,认为万福煤矿深部应力状态受控于鲁西南地区区域构造应力场。
The North China area is divided into 11 sub-districts.Based on the recent 1 111 focal mechanism solutions of moderate and small earthquakes in North China,distribution features of the principal stress direction are analyzed employing grid test method.The result shows that the horizontal action plays a main role in the present tectonic stress filed in North China and the predominant directions of the maximam principlal compressive stress are NEE and EW.The directions of the maximam principlal compressive stress are EW in Tangshan sub-district and Southern Shanxi sub-district.The directions of the maximam principal compressive stress in other sub-districts of North China are NEE with values between 60° and 80°.The in-situ stress measurement by hydraulic fracturing in deep rock in Wanfu coal mine shows that the direction of the maximum horizontal compression stress is between 40° and 80°,which is well consistent with the analysis result of focal mechanism solutions of moderate and small earthquakes in the southwest of Shandong Province.Based on a tectonic comparison,the deep stress state in Wanfu coal mine is closely related to the tectonic stress filed in the southwest of Shandong Province.
