邢台矿区三维地应力测量及应力场分析

Measurement of In Situ Stresses and Analysis of Stress Field in Xingtai Mining Area

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 principle and characteristics of stress measurement with the CSIRO method and the main procedures of in situ stress measurement carried in 4 coal mines of Xingtai mining area are introduced. The results show that overburden stress is prominent at shallow level, but tectonic stress at deep level, and that the maximum principal stress is sub horizontal stress in the NNE direction. The measurement results are agreeable to the general regularity of the stress field in North China.
