There are a large number of goafs and other potential safety hazards because it is difficult to form caving layerat theexisting bottomless sublevel caving layer method in Anhui Longqiao iron mine. Various mining scheme, such as the analytic hierarchy process and fuzzy comprehensive evaluation method were adopted to evaluate and optimize comprehensively. In the process of choosing optimal mining program, comprehensive evaluation model was established by converting production capacity, the cost of mining, tons of stripping ratio and labor intensity into judgment matrix. Comprehensive superiority of each mining scheme was calculated by fuzzy mathematics method to obtain the superior degree of alternative mining scheme in Longqiao iron deposit, which is 33.8 %, 21.3 %, 26.7 %, 25.2 %, respectively. As a result, the first mining scheme is the optimal mining program.%针对安徽龙桥铁矿现有的采矿方式无底柱分段崩落法中崩落层难以形成,存在大量采空区等安全隐患问题.提出采用层次分析法和模糊数学方法对多种采矿方案进行综合评判和优选,在选择较优采矿方案的过程中,针对影响采矿方案的指标建立采矿方案综合评判指标体系,将生产能力、采矿成本、千吨采切比和劳动强度等转换成判断矩阵,从而建立模糊综合评判模型,最后采用模糊数学方法计算出每个采矿方案的综合优越度,得出龙桥铁矿的备选采矿方案的各优越度为33.8%,21.3%,26.7%,25.2%,因此第1种采矿方案为较优采矿方案.
