基于层次分析法,综合考虑生产、安全和环境3大类因素,建立科学、全面的矿山采矿方法选择的指标评价体系,并得到了指标体系中各种影响因素的权重。以灵宝地区金源矿区金矿为实例,基于模糊数学和最大隶属度理论,根据各因素的组合权重,建立模糊综合评判模型,进行分析和计算,得到最终的评判向量。结果表明,浅孔房柱法为该矿最佳采矿方法。专家调查法得出的评估结果和矿区实际情况,证明了应用层次分析法和模糊理论选出的矿体采矿方法具有较强的适应性和科学性。
Based on the analytic hierarchy process and comprehensively considering the three major factors of production, safety and environment, a scientific and comprehensive index system for the selection of mining methods is established, and the weight of various influencing factors in the index system is obtained. Taking the gold mine in Jinyuan mining area in Lingbao area as an example, based on the fuzzy mathematics and the maximum membership degree theory, a fuzzy comprehensive evaluation model is established according to the combination weights of various factors, and the final evaluation vector is obtained. The results show that shallow hole column method is the best mining method for the mine. The results of expert investigation and the actual conditions of the mining area prove that the orebody mining method selected by AHP and fuzzy theory has strong adaptability and scientificity.
