Abstract:

This paper, based on the geology of Pb-Zn mines in Yunshan province, presents four mining methods, applies the fuzz synthetic evaluation to establish a synthetic model digitizing all fuzz or subjective factors during mining activities. An evaluation system based on the factors can be used to work out an optimized mining plan, which can be influenced by many factors. This factors are fuzz, random and unknown. The traditional mining plans are easily subject to the subjective experience. The fuzz synthetic evaluation has been proved to be effective, offering a scientific reference for mining plans.

Key words: fuzz synthetic evaluation, mining methods, model, optimization

摘要：

文章论述了云南省铅锌矿山现有情况和地质条件，提出可能的4种矿山采矿方法，应用模糊综合评判法，建立矿山采矿方案的模糊综合评判模型，将采矿过程中的各种模糊或主观因素定量数字化，给出量化后的影响因素评判体系，构造评判矩阵，经过模糊运算，得到了最优采矿方案。采矿方案选择受多种因素的影响,而这些因素又带有极大的模糊性、随机性和未知性, 传统的采矿方案选择容易受到主观经验的左右而不能正确反映实际情况。实践证明：模糊综合评判法对采矿方法优选是可行的，符合工程实际需要，为该矿的采矿方案选择提供了决策依据。
