中文摘要：
为了对高海拔地区的采矿方法进行科学评判，避免经验类比法的主观随意性，以西藏自治区某多金属矿为工程背景，将采矿方法的选择转化成系统工程决策问题，运用层次分析法综合考虑经济、技术、安全、环境和资源5大因素，构建了较为全面的层次评价指标体系，得到了合理的权重矩阵；然后采用模糊综合评价法确定了隶属矩阵并根据计算结果得出了理论最优方法；最后提出了一套将理论与实际结合的最优采矿方法。实际应用表明：层次分析法与模糊综合评价法相结合具有较强的逻辑性、系统性和实用性，不仅能为高海拔地区的采矿方法选择提供依据，也为类似的方案优化问题提供了新方法。
英文摘要：
In order to guarantee the scientific accuracy in selecting the mining method and to avoid the subjective ar- bitrariness of experience analogy method in high-altitude areas, the mining method selection was changed into the systems engineering decision with a polymetallic ore in Tibet autonomous region as the engineering background. In consideration of five factors of economy,technique, safety, environment and resources, a comprehensive hierarchy structure of evaluation in- dexes was built by Analytic Hierarchy Process to get a reasonable weight matrix. Then Fuzzy Comprehensive Evaluation method was used to determine membership matrix and calculated for a theoretical optimal method. Finally,the optimal min- ing method was proposed by the combination of theory with practice. The practical application shows that the AHP-FCE method is highly logical, systemic and practical. It not only can be used as a guideline for mining method selection in high- altitude areas, but also provides a new way for the similar optimization problem.
