摘　　要：采用固—液耦合相似模拟实验的方法,研究煤层开采中因顶板垮落、放顶垮落造成的顶板突水通道的变化规律。结合工程实践,系统分析了工作面富水覆岩因采动岩体裂隙动态发展的普遍规律、分布特征及含水层潜水的渗流过程;对煤岩体的变形和裂隙渗流机理进行了初步的探讨,可为煤矿顶板突水防治提供理论依据。In this paper,the change rules of water-inrush channels in the roof caused by roof caving and breaking during coal mining was studied through solid-liquid coupling simulation experiments.Systematic analysis was made on the dynamic developing rules and distribution characteristics of rock cracks caused by excavation in water-rich cover rock as well as the underground water seepage process in combination with the engineering practice;preliminary discussion was conducted on the deformation of coal-rock body and the seepage mechanism from cracks,this can provide a theoretic basis for the prevention of water burst from roof.
