摘　　要：根据山东新城金矿2008年末矿山生产能力由原1500 t/d提高到2500 t/d的新变化,深入分析该矿V#矿体的开采技术条件矿山地质,提出了适应该矿开采条件和新增生产能力需要的4种采矿方案。在此基础上,建立了采矿方法优选的综合评判模式,对其技术经济指标、隶属度、权矩阵的确定进行分析,得出4种方案的优劣顺序,最终选定应力拱连续开采上向水平分层充填采矿法作为该矿的采矿方法。通过实践证明,采用该方法取得了良好的经济效益,证实采矿模糊优选模式的评价结果可靠,适用性强。The production capacity of Xincheng Gold Mine was increased from 1500 t/d to the 2500 t/d at the end of 2008.In view of this,the mining conditions of the V# orebody in the mine was analyzed in depth,and 4 kind of mining methods to be suitable for mining conditions of the orebody and meet the need of the newly added production capacity were proposed.The comprehensive evaluation model for the optimization selection of mining method was established,and its technical and economical indexes,the determination of membership degree and Weighting Matrix of the indexes were analyzed.The best to worst sequence of the mining methods was obtained,cut and fill stopping under stress arch was selected as the best mining method at last.The practice shows that the application of this method can achieve good economic benefits,the evaluation result obtained by the fuzzy optimization model of mining method is reliable,and the fuzzy optimization model is of strong adaptability.
