利用FLAC~(3D)数值模拟软件建立了充填开采工艺方案的数值模型,将“垂直变形、水平变形、倾斜值和曲率”作为分析地表移动变形的4个指标,并且把模拟结果与相关规程进行对比,研究认为:增子坊矿似膏体巷式充填开采对增子坊村建筑物的最大影响均在二级影响标准内,影响区域均在距村庄50 m之外,范围很小,特厚煤层充填开采对地表变形控制效果显著。
The FLAC 3D numerical simulation software was used to establish the numerical model of filling process scheme. The vertical deformation, horizontal deformation, inclination and curvature were taken as the four indexes to analyze the surface deformation and the correlation between the simulation results and the correlation According to the study, the study shows that the largest influence of alley-like filling of Zengzifang mine on buildings in Zengzifang Village is within the second-level impact criteria, and the affected areas are all within a distance of 50 m away from the village with a small area. Extra-thick seam filling and mining on the surface deformation control effect is remarkable.
