摘　　要：大型露天矿山转为地下开采的采矿方法选择涉及诸多因素,其中许多因素具有模糊属性。本文根据南芬铁矿的矿床赋存条件及开采技术条件,基于理想点规范化方法和海明贴近度方法进行采矿方法初选,基于模糊多属性决策理论进行采矿方法终选,提高了采矿方法优选的科学性。采用主客观组合权重法确定采矿方法各影响因素的权重,使得权重的确定更加合理,增加了优选结果的准确性。优选出南芬铁矿露天转地下开采的采矿方法为无底柱分段崩落法。根据南芬铁矿露天转地下开采的采矿工程设计的专家评审意见,本文优选出的采矿方法技术上可靠、经济上合理,可在实际生产中应用。There are a number of parameters related with mining method optimization of transferring large scale open-pit into underground mining, of which many have fuzzy features. Based on deposit and mining conditions of the Nanfen iron mine, the ideal point method and the Hamming approach degree method were used for primary selection of possible underground mining methods. The fuzzy multi-attribute decision-making method was used for final optimization of mining method to ensure adaptability and comprehensiveness of underground mining method selection. A subjective-objective coupling weighting method was used to determine weights of various factors influencing mining method selection, which would prove reasonableness of determining weight coefficients. Finally, the sublevel caving method with no sill-pillar was selected as the underground mining method to be used in the Nanfen iron mine. According to the comments of mining experts in a judging meeting, the selected method would fill requirements of mining techniques and mining benefit.
