针对其它评价方法指标权重计算的不足,介绍了突变级数法模型的基本思想和评价步骤。采用突变级数法,对汝箕沟煤矿矿井通风系统改造过程中的三种采掘布局方案进行了评价分析。与其它评价方法相比较,突变级数法只需对评价指标进行重要性排序,在一定程度上避免了权重赋值的主观性,增强了评价结果的科学性和有效性。

Aiming at the shortcomings of the index weight calculation of other evaluation methods, the basic idea and evaluation steps of the mutation progression method are introduced. By using the method of catastrophe series, three kinds of mining layout schemes during the reconstruction of mine ventilation system in Rujigou coal mine were evaluated and analyzed. Compared with other evaluation methods, the mutation progression method only needs to sort the importance of evaluation indexes, avoids the subjectivity of weight assignment to a certain extent, and enhances the scientificness and validity of the evaluation results.
