| 摘 要： | 地下水的存在可以改变岩体的力学性质及覆岩应力状态,从而加剧由地下采煤诱发的地表变形、塌陷、地裂缝及水资源流失等采动损害现象;在采动损害过程中产生的覆岩中隔水层破断,又反过来改变地下水系统,引起井下突水事故和地面环境恶化。两者相互影响、相互制约,形成有利于采动损害发生、发展的互馈效应。在研究采动损害时,地下水是一个不可忽略的重要因素。

| Abstract: | Underground water may change the mechanics qualities and stress state of the cover rocks on the coal-mined bed,aggravating environmental hazards induced by coal mining such as deformation,subsidence,crevasse of the ground and loss of water resource.During environmental hazards induced by coal mining result in the fracture of water-lock rock layers and the change of the motion system of underground water so that cause mine flood and deterioration of ground environment.Interaction of the both factors makes for happening and developing of environmental hazards induced by coal mining.Therefore,underground water is an important factor,which cannot be ignored in studying environmental hazards induced by coal mining |
