| 摘 要： | 片帮型冲击矿压是煤壁局部失稳， 与煤壁层裂板结构的形成有关。分析了煤壁层裂板结构形成及压曲失稳破坏规律， 给出了裂纹扩展、贯通的应力判据以及随后形成的层裂板结构压曲失稳的条件， 并据此对冲击矿压进行模拟试验研究， 实验结果与理论分析基本一致。

| Abstract: | The rockburst in mines is local instability during excavation, which is related to layer crack plate construction. The formation and buckling of layer crack plate construction are analyzed. The stress criterion of crack growth and the construction buckling instability condition are given. The results of experiment based on this idea coincide basically with theory analysis. |

| Keywords: | rockburst layer crack plate construction buckling instability simulation experiment |
