基于AHP-TOPSIS的煤层底板突水危险性预测

Prediction of water inrush risk of coal seam floor based on AHP-TOPSIS

为预测矿井突水危险性,基于层次分析法(AHP)与逼近理想解排序法(TOPSIS)的理论,建立煤层底板突水预测模型。以滕北矿区中的6个矿井作为评判样本,通过AHP法确定各评判指标的权重;结合TOPSIS法建立AHP-TOPSIS综合评判模型,进行各评判对象的贴近度分析。优越度越大,矿井突水的危险性越低,评判结果与矿井实际生产情况是吻合的,因此该模型可作为煤矿水害预测与评价的一种新方法。

To forecast the mine water inrush risk, a coal floor water inrush forecast evaluation model was established based on AHP and TOPSIS. The model was used to six mine. The weight of the evaluation indices was determined by AHP, and then, the AHP - TOPSIS evaluation model was established with the basic theory of the technique for order preference by similarity to ideal so- lution. Superior degree shows that the mine is more safety which is consistent with practical situation, so this model can provide a new method for coal mine water disasters prediction.
