中文摘要：

为弄清煤岩动压灾害的主要影响因素,以煤矿冲击地压和工作面动载压架2种典型动压灾害为研究对象,通过对煤矿典型动力灾害事故的分析,分别提出了应力控制防冲理论和浅埋煤层顶板动载矿压前兆损伤模型,针对煤矿动压灾害的多尺度力学影响特征,建立了以应力控制为中心煤矿动压多级分源时空监控评价体系,成功解决了浅埋房柱式采空区下动载矿压压架及孤岛强冲击危险工作面切巷贯通的问题,可为煤矿动压灾害的防治提供参考。

英文摘要：

In order to know main influence factors of coal mine dynamic disaster,rock burst and support beakoff for dynamic pressure in workface were studied and the theory of stress control on rock burst and the precursor damage model of roof dynamic pressure in shallow seam was put forward through analyzing typical coal mine dynamic disaster. According to the multi-scale mechanical impact characteristics on coal mine dynamic disaster,the space-time monitoring and evaluation system of multilevel different-sources was established based on the stress control. It is successfully solved problems that are the shallow room and pillar goaf under dynamic load of mine pressure pressing frame and the tunnel through in the face of the strong impact of the isolated island. A useful reference for the prevention and control on coal mine dynamic pressure disaster was provided.
