摘　　要：针对煤矿采空区地面建筑地震动力灾变及抗震性能劣化研究不足的问题,通过分析国内外关于煤矿采动区建筑物保护的相关研究成果,分别从煤矿采动的次生灾害、煤矿采动建筑安全研究的紧迫性与严峻性、煤矿采动建筑安全性研究的不足、煤矿采动损害与地震灾害联合作用的致灾机制以及煤矿采动建筑地震动力灾变现有的研究成果与发展趋势进行了重点探讨,在分析煤矿采动建筑地震动力灾变机制的基础上指出了煤矿采动建筑地震动力灾变与防控研究迫切需要解决的学术问题,初步阐述了技术难题,为煤矿采动建筑的地震动力响应与灾变演化过程的防控提供参考借鉴。Aimed at the problems of insufficient research of seismic dynamic disaster and seismic performance degradation of buildings in coal mine goaf, through the analysis of related research results of buildings protection in coal mine goaf, we carried on the key discussion of the following important issues just as follows： the secondary dis- asters of coal mining, the urgency and severity researchs shortage of of buildings safety in coal mine goaf their shortage, the formative mechanism of joint action of coal mining damage and seismic hazard, and the existing research results and development tendency of seismic dynamic catastrophe of buildings in coal mine goaf. Based on the analysis of seismic dynamic catastrophe mechanism of buildings in coal mine goaf, we pointed out that the academic problems of the seismic disaster and prevention of buildings need to be solved urgently in coal mine goaf and preliminary revealed the technical problems of it need to be solved urgently, which can provided reference for the seismic dynamic response and prevention and control of disaster evolution process of buildings in coal mine goaf.
