| 摘 要： | 采用下向进路胶结充填法的矿山，回采断面尺寸是关系矿山安全生产的重要参数.结合工程实际，采用FLAC3D数值计算软件研究了矩形断面尺寸与采场稳定性的关系，对进路开挖后充填采场应力、位移、塑性区进行了分析.结果表明:进路高度对采场稳定性影响不大，跨度为6 m时采场处于失稳临界状态.

| Abstract: | The road way section size is very important in cemented underhand heading backfill mining for it relates to mining safety production. This paper studies the relationship between rectangular section size and stope stability using FLAC3D based on practical engineering. The distribution of stresses, displacement, plastic zone are analyzed. The results show that the height of road way has little effect on stope stability. The stope will be in the critical state of instability when the span is 6 m. |
