锡矿山南矿保安矿柱锌厂区域近地表安全回采研究与应用

Research and application of near surface safe mining in zinc plant area of security pillar in Xikuangshan south mine

锡矿山南矿锌厂区域矿体赋存靠近地表,被划定为保安矿柱,属于难采矿体的开采。本文通过采用先进的采矿方法与工艺,建立浅部充填系统处理大量空区等有效措施,近地表保安矿柱的回采安全性得到了提高,并在矿山生产实践中得到了推广应用。

The orebody occurrence in the zinc plant area of the South tin mine is close to the surface,it is designated as safety pillar,mining belonging to difficult mining bodies.In this paper,through the selection of advanced mining methods and technology,the establishment of shallow filling system to deal with a large number of goafs and other effective measures,the mining safety of the safety pillars near the surface has been improved,it has been popularized and applied in mine production practice.
