备注

针对煤矿采空区地下岩体结构的地震安全防护不足的问题,分别从煤矿采空区灾害的特征与危害、煤矿采空区的形成与基本特点及煤矿采空区失稳破坏的基本模式等方面深入研究煤矿采空区场地可能导致的次生灾害。通过分析煤矿采空区地下岩体结构地震灾变的相关研究成果,总结煤矿采空区地震安全防护所涉及的关键安全问题,揭示地震作用下煤矿采空区的场地稳定性与地下岩体结构安全防护迫切需要解决的技术难题,为采煤沉陷区工程建设及地震安全防护提供参考。

Aimed at the problems of insufficient research of the seismic safety of rock mass structure in coal mine goaf,the secondary disasters caused by coal mining goaf field were delved into through the related research of the characteristics and the harm of the disaster in coal mine goaf,the formation,the basic characteristics,and the basic model of instability and failure of coal mine goaf respectively. Through analyzing related research results of seismic dynamic disaster of rock mass structure in coal mine goaf,we summarized the key problems of safety control of seismic dynamic disasters,and revealed technical problems of stability of the coal mine goaf field and safety control for underground rock mass structure,so it can provided the reference for engineering construction and safety protection in coal mining subsidence areas.
