钻孔卸载法防治岩爆的机理及其数值模拟
Mechanism of Bore Hole Drainage Method in Rockbursts’s Prevention and Simulation
随着采矿深度的增加，地下工作面及其周围岩体的原岩应力成线性增加，导致了岩体失稳现象的增加，特别是引发了许多以岩体猛烈突然破坏为特征的岩爆,极大的威胁到了井下施工人员及设备的安全，给矿业开采带来了不可估量的损失。文章引入了一种预防岩爆的简单而有效的方法:钻孔卸载法,并在传统的研究层面上采用了ANSYS分析软件，对岩石受围压及钻孔卸载的力学模型做了数值模拟，并由分析得出了该方法的可行性.钻孔卸载法较其它预报、预防原理简单、操作方便.可用于对现实岩爆问题的指导. 因此，可以说钻孔卸压预防岩爆问题的研究对岩爆的预测、预防有重要的现实意义.
we develop one simple but efficient method to prevent rockburst: bore hole drainage; Finally the ANSYS analysis software is used in the traditional research，we have made the numerical simulation on model which is besieged to the rock presses and the bore hole drainage, Through the analysis, this method can be considered feasible. and obtained. The bore hole drainage prevention method is simple compared with other methods, which can be used in practical rockbursts. Therefore, it can be said that the bore hole drainage method has very important meaning to practical rockbursts forecast and prevention.
