采煤沉陷区稳定性综合评价指标权重的确定方法研究

Research on Confirming Weights of Evaluation Indexes of Mining Subsidence Area Stability

采煤沉陷区稳定性综合评价指标体系中各指标权值的大小合理与否,在很大程度上影响到评价结果的有效性,确定各指标权值是建立数学综合评价模型的关键之一。比较分析了确定采煤沉陷区稳定性综合评价指标权重的3种方法,认为采用层次分析法来确定采煤沉陷区稳定性各指标的权值较为合理。

Whether the weights of every index in comprehensive evaluation system of stability of coal mining subsidence are reasonable or not largely influence validity of evaluation results. Confirmation of evaluation indexes is one of the key of establishing mathematic evaluation model. 3 methods of confirming weights were compared in this paper and the result showed that AHP is fitter than else.
