摘要:
为研究临近断层工作面采动诱冲规律，首先对开采与断层应力之间的影响进行理论分析，再利用正交实验设计合理的实验方案，采用有限元软件FLAC3D对各方案进行数值模拟实验，提取25组数值模拟实验数据，最后基于层次分析法对各影响因素的组合权重进行理论计算，分析各影响因素对断层冲击地压的影响大小。结果表明：开采深度对断层冲击地压的影响最大，断层内摩擦角次之，断层黏聚力影响最小，且断层黏聚力和开采深度对断层冲击地压影响的差异较大。
Abstract:
In order to study the laws of mining-induced rock burst in the working face near the fault,the theoretical analysis on the influence between mining and fault stress was carried out,and a reasonable experimental scheme was designed by the orthogonal experiment.The finite element software FLAC3D was used to carry out the numerical simulation experiments on each scheme,and the data of 25 sets of numerical simulation experiments were extracted.Finally,the combination weight of each influencing factor was theoretically calculated based on the analytic hierarchy process,and the influence of each influencing factor on the rock burst of fault was analyzed.The results showed that the mining depth had the greatest influence on the rock burst of fault,followed by internal friction angle,and fault cohesion had the smallest influence.The difference between the cohesion force of fault and the mining depth on the rock burst of fault was relatively big.
