摘　　要：坚硬顶板下特大型采空场的处理是中国普遍存在的、特有的一类采矿技术难题。国内外已有的采空区处理方法中能解决冲击地压问题的,应用成本昂贵。为了经济有效地处理全面采矿法等空场法遗留的大量采空区及矿体残采,在国内外采空区处理与利用方法的基础上,提出了切槽放顶法和切顶与矿柱崩落法,并应用数值模拟、相似模拟和岩体声发射技术研究了各新方法的基本参数的设计方法和实施效果的分析、评价方法,形成了针对缓倾斜采空区处理的从理论分析、方案设计、现场实施到效果观测的一整套可供推广借鉴的理论、实施和评价体系。实践表明,提出的理论、实施和评价体系是技术可行、经济合理、简便适用的,具有重大的社会意义和重要的经济价值。Abandoned stope disposal is a great problem of mining technology and production safety. In current, domestic and foreign methods disposing abandoned stope, it was expensive that they could solve the problem rockburst. In order to dispose a great deal of abandoned stope left behind in breast method and so on openstope method and extract out remnant mine economically and effectively, on the basis of domestic and foreign methods disposing and utilizing abandoned stope, local grooving top-caving and roof cutting and pillar dilapidation is proposed by controlled explosion in this paper. And their methods designing the basic parameters and analysing and evaluating the effective cutting roof are studied by numerical simulation, similarity simulation and Acoustic Emission （AE） techniques of rock-mass. In a word, a set of the method and actualizing and evaluating system is put forward that may be extended and used for reference. The integral method and actualizing and evaluating system includes analysis method, project design method, the method carrying out and monitoring and evaluating. The result shows that it is technologically feasible, economically reasonable and simple suitable, and it has the significant social significance and the important economic value.
