介绍了空心包体法地应力测量的原理、特点及在邢台矿区4个矿井进行三维地应力测量的主要过程,并且对测量结果进行了分析.结果表明:邢台矿区浅部以自重应力为主,深部构造应力显著,最大主应力为北东偏北向的近水平压应力.测量结果与华北地区地应力场总体变化规律吻合.
The principles and characteristics of stress measurement of hollow inclusion method and the main process of three - dimensional ground stress measurement in 4 mines in Xingtai mining area are introduced. The measurement results are also analyzed. The results show that the shallow part of Xingtai mining area is dominated by self-weighting stress, and the deep structural stress is significant. The maximum principal stress is the north-east-northerly horizontal compressive stress. The results are in good agreement with the general changes of the in-situ stress field in North China.
