国外某铜锌矿采空区治理方案研究

采空区的存留会对地表、地下开采都产生危害,需要及时治理。根据国外某铜锌矿的实际条件,分析了可能会对地表和地下开采产生的危害。为避免潜在危害发生,在完成采空区三维建模、明确其空间位置关系的基础上,进行采空区稳定性定性评价,将采空区划分为单独治理单元,进行治理方案筛选。结果显示,筛选出的采空区治理方案既能保证矿山的安全生产,也能获得较好的经济、社会效益。

Study on goaf management of a Cu-Zn Mine in abroad

The residual goaf has damage on the surface and underground mining. And it should be treated timely. According to the actual conditions of the mine, this paper analyzes the probable damages to the surface and underground mining. For avoiding damages happening and based on the goaf 3D modeling and clear goaf space relationship, this paper passed judgment on goaf stability. Then, it divided underground goaf to be single management unit for selecting a suitable treatment project. The result can not only guarantee the safety in production, but also obtain good economic and social benefits.
