为提高煤炭资源采出率且减小开采对地表建筑物和铁路的影响,防止开采期间可能出现的安全隐患,以九龙煤矿地质采矿条件为基础,提出3种开采方案,运用FLAC3D模拟软件对各方案开采地表各移动变形量进行预计,并分析对建筑物及铁路线的影响程度,选出最佳合理开采方案。结果表明,采用方案2进行开采,技术经济合理,安全性更有保障,地表移动变形对构筑物的采动损害综合影响程度较小。 In order to improve the recovery ratio of coal resources and reduce the impact of mining on surface buildings and railways and to prevent potential safety hazards during the mining period, three mining schemes are proposed based on the geological mining conditions in Jiulong Coal Mine. FLAC3D simulation software Plan the movement of the surface deformation of the ground is expected to predict and analyze the extent of the impact of buildings and railway lines, select the best and reasonable mining program. The results show that mining with scheme 2 is technically rational and economical with more security, and the impact of surface deformation on the mining damage of structures is less.
