基于层次分析法的运输提升限制因素权重分析

为更科学合理地优化矿山运输提升系统，在分析某矿山运输提升运行限制因素的基础上，运用层次分析法建立了这些限制因素的AHP层次结构模型。通过构造判断矩阵和AHP模型的求解，得到了限制因素的权重结果：其中多级提升效率低权重比例最大，达35.2%，斜井缺乏统一设计和中段运输效率低权重分别达到15.04%与14.55%，其余各因素均未达10%。单排序和总排序判断矩阵一致性检验均有，一致性良好。表明通过层次分析法确定矿山运输提升运输系统限制因素相对重要性是可行的。分析结果为运输提升系统的优化决策提供了依据，进而给出优化意见，重点从改善多级斜井串车提升方式、做好深部运输提升的统一设计和发挥大中段运输作用3方面进行。

Weighting Analysis of Transportation and Lift Limiting Factors Based on AHP

In order to reasonably optimize the mine transportation and hoisting system，an AHP(Analytic Hierarchy Process)model of haulage and hoisting limiting factors was established based on the analysis of the factor limiting the transportation and hoisting operation in a certain mine by using the AHP.The weights of the limiting factors were obtained by constructing judgment matrix and solving the AHP model.The multistage lift was low efficient and had the largest weight of 35.2%.The shaft lacks of unified design and the transport efficiency at middle is lower.These two factors' weight occupied 15.04% and 14.55%，respectively.The rest of the factors were not up to 10%.The judgment matrix consistency of single order and the total order are checked as with good consistency.The results showed that it was feasible to obtain the relative importance of limiting factors in mine transport and hoisting transport system by AHP.The analysis results provided the basis for optimizing decision and some recommendations were given.The work should focus on improving the multistage slope lift way，accomplishing the uniform design in deep transportation promotion and paying attention to sublevel haulage.
