摘 要:以条带法开采南屯煤矿村庄下压煤为例,通过理论计算确定条带开采的具体方案,并使用UDEC对该方案进行数值模拟验证,模拟结果显示,最大地表下沉量、倾斜量、曲率值、水平移动量和水平变形量均不超过村庄建筑物Ⅰ级破坏等级,既可以有效地保护地面村庄的建筑物,又可以以较高采出率安全高效地采出村庄下压煤。Abstract: Based on strip mining under the village of the Nantun coal mine, the specific scheme of strip mining is determined by theoretical calculation and the numerical simulation verification which are carried out by UDEC. The research result indicates that all of the maximum amount of surface subsidence, the amount of tilt, the value of curvature, the amount of horizontal movement and the level of deformation meet the requirements of the class I on village building damage level which are contributing to extracting safely and efficiently with a higher recovery rate and the protecting the surface building.
