| 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. |
