无底柱分段崩落法在羊耳山铁铜矿的应用

Application of sublevel caving without sill pillar in Yang'ershan Fe-Cu Mine

为提高开采效率,降低生产成本,增加矿山经济效益,在详细分析羊耳山铁铜矿矿体开采技术条件的基础上,采用无底柱分段崩落法作为其矿体开采的主要方法。详细论述了该采矿方法适用性、回采工艺参数及现场管理相关经验。通过实践证明,在羊耳山铁铜矿矿体开采中,无底柱分段崩落法在技术上是可行的,在经济上是合理的。

In order to improve mining efficiency, reduce production costs and increase economic benefits, based on a detailed analysis of mining conditions in Yang＇ershan Fe-Cu Mine, sublevel caving without sill pillar method is adopted as the main method. This paper discusses the applicability of this mining method, mining processing parameters and site management experience. Practice has proved that sublevel caving without sill pillar method used in Yang＇ershan Fe-Cu Mine is technically feasible and economically reasonable.
