锡铁山铅锌矿采空区治理方案优选

Optimization of the Goaf Governance Program in Xitieshan Lead-zinc Mine

锡铁山铅锌矿存在采空区数量多、规模大、空间关系复杂的问题。为了安全开采深部矿体,采用3DMine软件建立铅锌矿采空区立体可视化模型,掌握采空区的三维形态,统计出采空区体积总量超过900万m³。对采空区进行现场调查与分析,从安全、成本、治理周期等方面对不同的治理方案进行比选。结果得出,该铅锌矿采空区治理适合封闭隔离和崩落围岩形成缓冲垫层的方案。

The Xitieshan Lead-zinc Mine has the problems of a large number of goafs,a large scale,and complex spatial relationships.In order to safely mine deep ore bodies,3DMine software is used to establish a three-dimensional visualization model of the lead-zinc mine goaf,master the three-dimensional form of the goaf,and calculate that the total volume of the goaf exceeds 9 million m^(3).Field investigation and analysis were carried out on the goaf,and different treatment schemes were compared and selected from the aspects of safety,cost and treatment cycle.The results show that the goaf treatment of the lead-zinc mine is suitable for the scheme of closed isolation and formation of buffer cushions in collapsed surrounding rock.
