摘　　要：研究了云南某铁矿2#矿体,根据矿山概况和矿床技术条件,可以采用方案一:不拉顶中深孔房柱采矿法,方案二:拉顶预控中深孔房柱采矿法,方案三:拉顶不预控中深孔房柱采矿法.为使开采方法最优引入模糊数学层次分析法和变权法,利用模糊数学综合评判,确定最优采矿方法.This article researches 2# iron deposit in Yunnan, according to the technical condition of mining survey and deposit, the following processing methods can be conducted： firstly, pillar mining method instead of pulling the medium-length hole in room; secondly, pulling top pre-controlling of room and pillar mining method in deep hole; thirdly, pulling top of room and pillar mining method in deep hole but no pre-controlling. In order to certain the reasonable mining method, fuzzy hierarchy analysis method and variable weight method are utilized. By using fuzzy comprehensive evaluation, the optimal mining method is determined.
