摘要: 矾山磷矿西采区矿体赋存于承压水下,为防止承压水沿开采裂隙灌入井下,现场采用点柱上向水平分层充填法采矿,通过FLAC3D数值模拟软件,对采场的顶板变形和应力分布进行分析,确保了采场安全开采。

Abstract: The mine's orebody of western area of the Fanshan phosphate rock occurred under the confined aquifer.In order to protect the mining stopes from being submerged by the confined aquifer from the fractured zone generated while mining. So,the filling method of the point to level of hierarchy pillars is adopted to mining in this area. The roof deformation and stress distribution of the stope is numerical simulated by the FLAC3D software,so as to guarantee the security of the stope mining.

Key words: FLAC3D software, Numerical simulation, Roof deformation, Distribution of stress
