【摘要】 能量积聚以及积聚的位置是判别冲击矿压是否发生的2个重要参数,运用ANSYS/LS-DYNA软件对应力波作用下巷道围岩的能量积聚过程、巷道的埋深H对能量积聚的影响进行了有效的数值模拟,得一定围岩应力状态下巷帮围岩能量积聚的大小、位置等特征。结果表明:应力波是巷帮能量积聚,继而诱发冲击矿压的重要因素;巷道的埋深H决定了最大能量密度（U_d）_max值的大小及其到巷帮的距离。研究结果对揭示煤矿冲击矿压的诱发机理,及冲击矿压发生的预测预报具有重要意义。更多还原

【Abstract】 The energy accumulation and its position are two main factors to be used to judge the rock burst occurring. Software ANSYS/LS-DYNA is applied to simulate the process of the energy accumulation and the effect of the depth of roadway to the energy accumulation,giving rise to the character of the energy accumulation and its position. The research results show that the stress wave is an important factor to accumulate the energy in surrounding rock and induce the rockburst;and the depth of roadway H decides value of the maximal energy density（U_d）_max and the distance between its position and the surrounding roadway.The study results have an important significance to reveal the mechanism of inducing rockburst and to forecast the rockburst.更多还原
