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。
Taking strip mining of coal in Nantun coal mine as an example, the specific scheme of strip mining was confirmed by theoretical calculation. The program was verified by numerical simulation using UDEC. The simulation results show that the maximum surface subsidence, Curvature values, horizontal movements and horizontal deformations do not exceed Class I damage levels of village buildings, which can effectively protect the buildings of the village on the ground and can safely and efficiently recover the coal under the village with a high recovery rate.
