摘　　要：针对煤矿采空区的地震安全及矿区地下结构抗震研究不足的问题,通过分析国内外专家学者对地下结构的地震动力灾变与防控的相关研究成果,分别从煤矿采空区灾害的特征与形成原因、煤矿采空区动力灾害研究的紧迫性与严峻性、地下结构抗震研究领域的已有优秀研究成果以及煤矿采空区地震动力灾变研究的不足及发展趋势等方面进行了分析探讨,在分析地下结构抗震研究成果的基础上指出了煤矿采动区地震动力灾变与安全防控迫切需要解决的问题,系统凝练了地震作用下煤矿采空区及地下结构的地震损伤力学机制与灾变控制的核心学术问题,初步揭示了煤矿采空区的地震动力响应、煤矿地下结构的地震破坏模式迫切需要解决的技术难题,为煤矿采空区的地震动力稳定性及煤矿采空区地下结构的地震灾变防控提供参考和借鉴意义。Aimed at the problems of insufficient research of the seismic safety of coal mine goaf and seismic of the underground structure in mining area,through the analysis of the related research results of the prevention and safety control of seismic dynamic disasters of underground structure by domestic and foreign experts and scholars,we analyzed and discussed the follow ing important issues just as follow s： the characteristics and forming reasons for disaster in coal mine goaf,the urgency and serious situation of dynamic disaster research of the coal mine goaf,the existing excellent research results of seismic research field of underground structure and development trend and shortage of seismic dynamic disaster research of coal mine goaf etc.. On the basis of the research result of the structural seismic of the underground structure,we found out that the urgent problem of the prevention and safety control of seismic dynamic disasters in the coal mine goaf needed to solve immediately. Then we systematically concluded the core academic problems of seismic damage mechanics and disaster control of coal mine goaf and underground structure,and preliminary revealed the urgent technical problems of the seismic dynamic response of coal mine goaf and seismic dynamic damage patterns of coal underground structures,so it can provided reference for the seismic dynamic stability and the prevention and safety control of seismic dynamic disasters of coal mine goaf.
