摘要 本文利用潘北煤矿55个典型水样,选取Ca2+ 、Mg2+ 、Na+ +K+ 、HCO3 - 、Cl-、SO4 2- 、碱度、总硬度、矿化度以及pH共10个判别指标,基于多元逐步Bayes判别分析理论,建立突水水源判别模型,并进行回判检验。结果表明:该模型的判对率高达98%,对矿井突水水源判别及防治水工作有一定的指导意义。

Abstract :Based on the 55 typical water samples in Panbei coal mine, ten discriminative indexes ( Ca2+ 、Mg2+ 、Na+ +K+ 、HCO3 - 、Cl- 、SO4 2- 、alkalinity、total hardness、TDS and pH ) have been selected. Combine with multivariate stepwise Bayes discriminative analysis theory, the discriminative model of water-inrush has been established and verified. The result showed that the accuracy rate of the model was so high that it has a certain guiding significance for mine water-inrush discrimination and the work of water prevention and control.
