摘　　要：本文针对1160采区地面村庄稠密、受水威胁严重的问题,综合考虑各种因素,对建筑物下及承压水上采留比理论公式进行推导计算。采取概率积分法进行地表下沉预计,岩体水力学法分析底板破坏,并提出采宽50m、留宽50m的开采方案,运用FLAC3D数值模拟、底板突水机理研究等手段对该方案进行研究,得出该条件下的可行方案。Aiming at the problem of dense ground villages and serious water threat in 1160 mining area, this paper deduces and calculates the theoretical formula of mining retention ratio under buildings and confined water, taking into account various factors. The probability integral method is used to predict the surface subsidence, the rock mass hydraulics method is used to analyze the floor failure, and a mining scheme with a mining width of 50m and a retaining width of 50m is proposed. The scheme is studied by means of FLAC^3D numerical simulation and the mechanism of floor water inrush, and the feasible scheme under this condition is obtained.
