摘要
结合归来庄金矿的工程实例,构建了露天转地下开采人工境界矿柱法关键技术层次分析递阶结构模型和判断矩阵,进行一致性检验并计算最大特征值λmax,采用五级风险影响评价等级建立人工境界矿柱的模糊评判矩阵,并根据层次分析法的权重进行模糊合成和综合评判,得出总指标露天转地下开采人工境界矿柱法关键技术的风险属于较低风险。
Combining with Guilaizhuang gold mine engineering example, establishes critical technology hierarchical analysis structure model and identification matrix of FAHP from open to undergrounding mining, further tests and calculates maximum value λ_max, applies five-grade risk influ- encing evaluation method, establishes fuzzy evaluation matrix of artificial boundary pillar, and carries out fuzzy composition and assessment. In the end, it points out that： critical artificial boundary pillar technology method risk is relatively low by altering open to underground mining.
