摘　　要：Baluba铜矿是一座开采近40 a的老矿山,由于矿体缓薄、形态多变,导致开采难度大。通过分析该矿历史上的采矿技术资料,总结了以往各采矿方法的优缺点,针对矿山不同区域、不同产状的矿体,提出了6种适用性较强的采矿方法。基于模糊综合评判法,建立采矿方案综合评价指标体系,对井下五类矿体进行采矿方案优选。生产实践表明,依据矿体的产状划分东采区矿块,分别配置最佳采矿方法,不仅降低了采切工程量,而且保障了矿山安全高效运行。Baluba mine is an old mine which has the mining history for about 40 years,it is very difficult to mine the gently inclined thin ore body with variable morphology. The advantages and disadvantages of the existing mining methods are summarized based on analyzing the exsisting mining technical reference,so the six suitable mining method are proposed to deal with the different occurrence ore bodies in different regions. Based on the fuzzy comprehensive evaluation method,the comprehensive evaluation index system of mining scheme is established so as to make optimization selection on the mining scheme of the five different kinds of ore bodies. The application shows that,according to the occurence of the ore body,ore blocks of the easting mining area are divided,which arecollocated with optimizationmining method. Therefore,the mining method proposed in this papercan not only reduce the amount of underground development,but also ensure the mine safe and efficient operation.
