Abstract:本文在充分考虑到岩石的非均匀性,存在的节理、裂隙等的基础上,运用岩石破裂过程分析系统(Rock Failure Process Analysis,RFPA)对灵新煤矿在开采过程中诱发的上覆岩层移动、离层以及垮落过程进行了的数值试验,并与相应的相似模拟结果进行了对比.结果表明,数值试验结果与相似模拟结果有较好的一致性.通过数值试验,不仅直观地反映了煤矿在开采过程中上覆岩层的动态变形、离层及其相应的破裂过程,更莺要的是可以通过数值试验,观察岩层移动过程中的应力场,从应力场的角度上分析诱发岩层移动破坏的本质.数值试验克服了物理试验中的高费用,周期长等缺点,为快速地对岩层移动进行预测、预报,避免灾害事故的发生,或者对采矿工艺进行优化等提供了新的方法.
