MEASUREMENT OF ROCK STRESS OF HONGLING COAL MINE
-
摘要:
为了了解红菱煤矿地应力状态和分布特征, 采用空芯包体应力解除法进行了地应力实测工作, 获得了该矿区3个水平3个测点的三维地应力状态。实测表明:该区地应力以水平构造压应力为主导, 三个测点的最大主应力均为NNE向, 最大主应力在18.32~21.5MPa之间, 最大主应力的大小是随深度的增加而增加的。中间主应力为铅直应力, 在13.1~14.79MPa之间。最小主应力在9.54~13.08MPa之间。测量结果可用于本矿区的生产设计, 并作为煤与瓦斯突出等矿山灾害评价的参考资料。
Abstract:To get a knowledge of in-situ stress and its distribution in the Hongling coal mine, a measurement has been done for the rock stress in coal mine area by using hollow inclusion gauge method. In this paper, the results of rock stress measurement of 3 levels are introduced, the characteristics of stress distribution are discussed.The results show that the principal stress goes in nearly NNE direction and ranges in value from 18.32 to 21.5 MPa.The horizontal stress takes the dominating place and has a bigger value than the vertical one.The middle principal stress is nearly vertical and changes in value from 13.1 to 14.79 MPa. Value of the minimal principal stress is 9.54~13.08 MPa.The value of in-situ stress increased with depth.The measurement results can be applied to mine design.
