摘　　要：Caving of mine roofs from water inrush due to anomalous pressure is one of the major disasters and accidents that can occur in mines during production.Roof water inrush can trigger a wide range of roof collapse,causing major accidents from breaking roof supports while caving.These failures flood wells and do a great deal of damage to mines and endanger mine safety.Our objective is to analyze the anomalies of water inrush crushing the support at the #6301 working face in the Jisan Coal Mine of the Yanzhou Mining Group.Through information of water inrush to the roof,damage caused by tectonic movements,information on the damage caused by roof collapse and the theory about the distribution of pressure in mine abutments,we advice adjusting the length of the working face and the position of open-off cut relatively to the rich water area.In the case of anomalous roof pressure we should develop a state equation to estimate preventive measures with＂transferring rock beam＂theory.Simultaneously, we improve the capacity of drainage equipment and ensured adequate water retention at the storehouse. These are all major technologies to ensure the control and prevention against accidents caused by anomalous water inrush in roofs,thus ensuring safety in the production process of a coal mine.从水流入的矿房顶的探穴由于异常压力是能在生产期间发生在矿的主要灾难和事故之一。房顶水流入能触发大量房顶倒塌，引起从打破房顶支持的主要事故当时探穴。这些失败充满井并且做很多损坏到矿并且危及矿安全。我们的目的到在工作的 #6301 压碎支持的水流入的异例在 Yanzhou 采矿组的 Jisan 煤矿面对的分析。通过到房顶的水流入的信息，损坏由构造运动引起了，损坏的信息在矿桥墩关于压力的分发由房顶倒塌和理论引起了，我们调整工作的脸的长度和打开离开的位置的忠告相对切了到富有的水区域。在异常房顶压力的情况中，我们应该开发一个州的方程估计有鈥渢r ansferring 的预防措施摇横梁鈥 ? 理论。同时，我们在宝库改进排水设备和保证的足够的水保留的能力。这些都是主要技术对异常的水流入在房顶引起的事故保证控制和预防，因此在一个煤矿的生产过程保证安全。
