| 摘 要： | 我国大部分矿区处于高烈度地震设防区，多年的采矿已在矿区累计形成了大面积多层悬空、塌陷区，而悬顶系统贮存了大量弹性能。文中描述了悬顶系统贮存弹性能的数学模型和地震等动力作用下的扰动荷载，探讨了悬顶系统在扰动作用下的释放能量的。因素和条件以及可能造成的灾害量级。

| Abstract: | Most of mining areas in our country are located in high intensity earthquake protected zone. Many years of mining activities have been formed large area land multilayer goaf and hanging arch, and hanging arch system has stored enormous elastic energy. The paper describesthe mathematic of models of elastic energy store of hanging arch system and dynamic load of earthquake force acting on hanging arch system, and discussed the factors at inducing released energy of the dynamic disturbing hanging arch system. |
