摘要
在矿井动力灾害影响因素中,地应力是最重要的影响因素之一。对平煤股份八矿、十矿和十二矿地应力进行了测量和分析,结果表明:平顶山东部矿区地应力以水平压应力为主导,应力升高区和应力梯度区对矿井动力灾害的发生起到控制作用。
In the influential factors of dynamic disaster in coal mine,the geostress is one of the most important ones.The measuring and analysis on geostress in Pingdingshan No.8 Coal and No.12 Coal Mine was made,the results show that,the horizontal stress plays the leading role in geostress of Pingdingshan eastern mining area,and the stress-increased area and stress gradient area controls functions to the dynamic disaster in coal mine.
