摘　　要：某铜矿矿体形态复杂,主要采用无底柱分段崩落法开采,贫化损失率较高。为了提高矿山生产效率,达到低投入、低贫化回收矿石的目的,通过模糊相似优先比法初选出采矿方法,使用模糊关系方程推测各方案的技术经济指标,再使用模糊综合评判法终选采矿方法,最终确定出阶段空场法和分段连续空场法的联合技术方案。通过在该铜矿的实施表明,阶段空场法适用于回收品位较高的厚大矿体,分段连续空场法适应于开采中厚分支矿体或盲矿体。The ore body of a copper mine has a complex shape and is mainly mined by sub-pillar cav⁃ing method,which has a high dilution loss rate.In order to improve the production efficiency of the mine and achieve the purpose of low investment and low dilution of ore recovery,the mining method is prelimi⁃narily selected by fuzzy similarity priority ratio method.The technical and economic indicators of each scheme are speculated by fuzzy relational equation,and then the fuzzy comprehensive evaluation method is used to finalize the mining method.Finally,the joint technical scheme of stage space field method and piecewise continuous space field method is determined.The implementation in the copper mine shows that the stage open-field method is suitable for the recovery of thick orebody with high grade,and the segment⁃ed continuous open-field method is suitable for the mining of medium-thick branch orebody or blind orebody.
