摘　　要：随着矿产资源逐渐减少以及充填采矿技术的成熟,原工业场地、村庄、道路等“三下”矿体逐渐进入回采可行性论证阶段。为探究某铁矿保安矿柱开采对地表的影响,结合矿山开采技术条件,采用数值模拟的方法,分别对矿山开采现状、按设计范围开采和统筹保安矿柱开采情况下的地表位移情况进行了计算。通过对比分析,该铁矿采用分段空场嗣后充填法统筹保安矿柱的开采对地表影响较小,在确保充填质量和帷幕注浆防治水的前提下,能够保证地表建(构)筑物的安全。With the gradual reduction of mineral resources and the maturity of filling mining technology,the original industrial sites,villages,roads and other"three under"ore bodies have gradually entered the feasibility demonstration stage of mining.In order to explore the influence of safety pillar mining on the surface of an iron mine,combined with the technical conditions of mining,the numerical simulation method was used to calculate the surface displacement of the current mining situation,the mining according to the design range and the overall planning of safety pillar mining.Through comparative analysis,the mining of the overall security pillar by the segmented open field subsequent filling method in the iron mine has little effect on the surface.Under the premise of ensuring the filling quality and curtain grouting to prevent and control water,it can ensure the safety of surface buildings.
