本文从地应力测量、岩石组构分析和模拟实验砰究等资料,确定北京煤岭弧形断裂附近地区的局部地应力场为旋扭应力场,自燕山运动晚期以来直至现今长期活动,外旋均作顺时针方向的旋扭运动。它与新华夏系现今区域地应力场的特征不同,前者最大主压应力迹线呈弧形弯曲,往东南收敛,向西北撒开;后者最大主压应力迹线作近北西西方向延伸。 In this paper, the local stress field in the area around the arc coal seam in Beijing Coal Mine is determined as the torsional-torsional stress field from the data of geostress measurement, rock structure analysis and simulation experiment. Since the late Yanshan Movement up to now, All clockwise rotation movement. It is different from the characteristics of the current regional stress field in the Xinhua-China region. The former principal compressive stress trajectory curves in an arc, converges to the southeast, and spreads to the northwest. The largest principal compressive stress trace of the latter extends near the NW and Westen.
