摘　　要：为了合理选择峨口铁矿地下开采方法,通过对峨口铁矿境界外资源赋存条件分析,推荐了适合于矿体开采的备选方案。在对备选方案进行技术经济及优缺点比较基础上,建立灰色数学模型,利用灰局势决策对备选方案进行优化选择,最终确定峨口铁矿地下开采采用无底柱崩落法,同时对无底柱崩落法配套装备进行了推荐。将灰局势决策应用于采矿方法优化选择中,为矿山决策提供了科学依据和便利。In order to select the optimal underground mining method for E kou Iron Mine, through analyzing the occurrence condition of out of the boundary iron minerals, the alternative scheme suiting for ore mining is recommended. On the basis of comparing the technical economic, advantages and disadvantages of the alternative, the gray math model is built and the optimal alternative program is selected by using the grey situation decision, finally choosing the pillarless caving method as the best program for the E Kou Iron Underground Mining. Meanwhile the accessory equipment for the pillarless caving method is recommended. It supplies the scientific basis and convenience under the grey situation decision used in optimi- zing the mining method.
