| 摘 要： | 运用弹性地基及薄板理论建立沿空掘巷顶板运动的力学模型 ,并用该模型分析了顶板的挠曲运动和内、外应力场。模拟分析表明 :沿空掘巷合理位置应位于断裂顶板平衡岩梁保护之下的内应力场区 ,掘进和开采的人为扰动对沿空掘巷的影响较小 ,巷道受力和变形也较小

| 关 键 词： | 弹性地基 综放沿空掘巷 内、外应力场 模拟分析 |

| Abstract: | Based on the theory of flexible groundsill and sheet, a mechanical model moving along free lane is built, and the character of the movement of crest and interior or exterior stress place analyzed. What the above does shows that the reasonable position along free lane locates interior stress place protected by the counterweight girder of fracture crest. Tunneling and mining have little influence on the place along free lane, pressure of lane and distortion. |

| Keywords: | flexible groundsill place along free lane in integrated mining interior or exterior stress place analysis of simulation |
