摘　　要：矿床开采产生大量采空区,易诱发矿区塌陷、矿震、滑坡、矿井突水等地质灾害。采空区的失稳问题一直以来是影响矿山安全生产的最主要的危险源之一。内蒙古某金属矿采空区的顶板暴露面积较大,形状极其不规则,分布范围广,重叠交错。采空区处理的方法有崩落法、支撑法、封闭与隔离法、充填法等。根据该矿山现状,通过对比分析,采用尾砂胶结充填的方法,对采空区进行处理,确保矿山安全生产。Mining has produced a large number of mined-out areas, which easily induce geological disasters such as mine subsidence, mine earthquake, landslide, water inrush and so on. The instability of goal has been one of the main dangerous sources, which affects the safety production of mines. The exposed area of the roof is very large in a metal mine of Inner Mongolia and the goal is in irregular shape with wide distribution and staggered overlapping. There are four methods in goal management, which includes caving method, support method, closed and isolation method and filling method. According to the present situation of the mine, the method of tailing-cemented filling should be used to deal with goal through comparative analysis to ensure the safety production of the mine.
