摘要
前进式和后退式是工作面开采的2种主要方式,在我国的一些矿区都有使用。以河南刑村煤矿为背景,基于FLAC3D软件,分析了不同开采方式下帮部和顶底板位移和应力的变化规律,得到了不同的开挖方式对巷道变形和稳定性的影响规律。
The advancing and retreating mining are two main ways of working face mining, which are used in some mines of our country. Taking Xingcun Coal Mine in Henan as background, the article analyzes the displacements and stresses change of the side, roof and floor under different mining modes by FLAC3D software. According to the results of the analysis, it gets the influence laws of different excavation modes on roadway deformation and stability.
