| 摘 要： | 采空区的稳定性问题除了岩体强度、节理、裂隙、层面等地质缺陷自身的因素外,地震、爆破、地下水等外界的因素也不容忽视.本文利用离散元软件UDEC模拟了地震波对天德石膏矿采空区塌陷的影响,分析了节理围岩在地震波作用下的运动情况,指出地震波的作用是采空区产生塌陷的诱发因素. |
| 关 键 词： | 采空区 地震 离散元 |

| Abstract: | Except for the inner factors of geological deficiency such as the strength of rock mass, joint, crevice and bedding plane, the external factors of earthquake blast, and ground water are also very important. This paper use numerical method simulates the effect of earthquake to the gob collapse in Tiande gypsum mine, analysis the motion of wall rock under the action of earthquake, and points out that the earthquake wave is the induced factor to this collapse. |
