摘　　要：对某采区村庄下似膏体充填开采进行FLAC3D数值模拟。研究了充填材料的配比和力学特性、充填工艺设计、模型的建立和计算过程。分析得出似膏体充填技术影响减沉效果的几点因素。For a certain mining area as the paste-like backfill under villages,the FLAC3D numerical simulation was built.The ratio and mechanical property of backfill materials were studied, as well as thedesign of backfill process,the modeling and the computational process.Some factors to influence the effect of mining subsidence based on the paste-like backfill technology were analyzed.

关 键 词：似膏体充填 数值模拟 地表减沉
