摘要:
蒲白矿务局西固镇下煤层开采是复杂条件的建筑物下厚黄土覆盖层开采。针对矿区开采的复杂地质、采矿条件和建筑群受采空区影响的问题,运用FLAC3D数值模拟预计、影响函数仿真模拟和相似材料模拟进行分析,确定了开采方案及相关参数。结果表明,运用变条带协调开采方案可以有效地控制地表移动和变形,从而保证了地表建筑物的正常使用和矿区的安全生产,为同类厚黄土覆盖层矿区控制开采沉陷灾害提供了可靠科学依据。
Abstract:
With the geology and mining conditions of the thick seam mining covered by thick loess and buildings location in Guxi village of Pubai mine area, the numerical simulation, expected function simulation and similar material simulation are applied to confirm the mining scheme and parameters.The results show the variable strip mining method can control the surface displacement and deformation effectively. Thus normal usage of buildings and safe mining production are ensured.Moreover it provides reliable and scientific foundation for the thick seam mining area covered by thick loess.
