【摘要】 地应力产生的原因十分复杂,但其在研究区域和采场稳定性问题方面,是必不可少的考量因素。通过对东升庙区域应力场及其演化分析,得到了矿区局部应力场的几个分布特征,掌握了矿岩层的形成与变化规律,探讨了同生断裂活动对矿岩体稳定性的影响。更多还原

【Abstract】 The causing of in-situ stress is very complex,but it is the essential factor in the research of stability of region and stope.Through the analysis of regional stress field’s evolvement,several distribution characteristics of local stress in mining area is advanced,the rule of formation and change of strata is mastered,the influence that caused by the synchronous fault to the stability of rock mass is researched.更多还原
