| 摘 要： | 采区巷道合理煤柱的留设关系到巷道稳定性以及巷道的维护和正常使用,通过理论计算和数值模拟,分析了不同宽度煤柱条件下3条采区大巷的围岩变形规律以及应力分布规律,得出了布置39采区工作面的合理位置以及距离采区巷道煤柱尺寸的合理宽度,为具有类似条件的巷道掘进和布置提供参考。 |
| 关 键 词： | 采区巷道 煤柱留设 煤柱尺寸 |

| Abstract: | Reasonable coal pillar leaving in mining area of roadway is relate to roadway stability and roadway maintenance and normal use.Through theoretical calculations and numerical simulation,the paper analyzes surrounding rock deformation and stress distribution laws of three mining area roadways under different width of coal pillar,achieves the arrangement of 39 mining area,as well as a reasonable width of coal pillar size from the mining area of roadway,which provides reference for arrangement and roadway excavation with similar conditions. |
| Keywords: | mining area of roadway leaving coal pillar size of coal pillars |
