摘　　要：针对急倾斜薄矿脉可选采矿方法有限、贫损指标控制难等问题,为科学合理选取采矿方法,建立了改进CRITIC和逼近理想解(TOPSIS)的评价模型,并应用到某铅锌矿采矿方法优选中。建立采矿方法综合评价指标体系,采用改进CRITIC法确定指标客观权重,通过计算综合优越度,得出中深孔落矿分段空场采矿法为最优采矿方法。现场工业试验表明:采用该采矿法获得了采矿损失率11%,矿块生产能力310 t/d的良好指标,有效提升了矿山经济效益,为类似矿山开采提供了新思路和技术。There are limited mining methods for steeply dipping thin veins and it is hard to control dilution and loss index.In order to properly select mining method,an improved CRITIC-TOPSIS evaluation model is established and applied to the selection of mining methods for a lead-zinc mine.The comprehensive evaluation index system for mining methods is established and the improved CRITIC method is used to determine the objective weight of the indexes.Based on the calculation of comprehensive advantages,it is concluded that the moderately longhole sublevel open stoping mining method is the best choice.Field industrial test shows that with the method,good indexes such as the mining loss rate of 11%and the ore block production capacity of 310 t/d are obtained.The method effectively improves economic profits and can provide new ideas and technology for similar mines.
