摘要
应用层次分析 (AHP)的基本决策理论 ,针对急倾斜煤层的赋存条件 ,提出了 6种技术上可行的采煤方法 ,并建立了目标层、准则层和方案层的层次分析模型。结合沙井矿煤层的具体条件 ,构造判断矩阵 ,求解矩阵的特征向量 ,最后确定了伪倾斜钢结构“八字形”
Applying basic policy-making theory and in light of occurring conditions of steep seam, the author has developed 6 technically-feasible mining methods and established the stratification analysis models for target level, criterion level and scheme. According to actual conditions of Shajing Mine's coal seam, judgement matrixes are constructed to solve for characteristic vector of matrixes. Finally, the coal-mining method using 'figure-eight' shield supports with a pseudo-inclined steel structure is more suitable for Shajing Mine's coal-mining.
