不连沟煤矿充水水源水化学特征分析及突水水源判别模型研究及应用

Chemical characteristics analysis of water-filled source water in Buliangou Coal Mine and research and application of water source water source discrimination model

为了快速有效地判别矿井突水水源,采用Fisher判别分析方法建立突水水源判别模型,在积累了大量水化学资料的基础上,对不连沟煤矿地下水水化学特征进行了分析与研究。首先使用训练样本进行了回判,回判准确率达到96%;然后使用判别模型对F6206工作面掘进巷道掘进过程中突(涌)水水源进行判别,判别准确率达到了90%,为不连沟煤矿突水水源判别提供了一种行之有效的方法。

In order to quickly and effectively identify the water source of mine water, Fisher＇s discriminant analysis method was used to establish the water source water source discriminant model. Based on the accumulation of a large amount of water chemistry data, the groundwater hydrochemical characteristics of Buliangou Coal Mine were analyzed and studied. Firstly, the training samples were used for the judgment, and the accuracy of the judgment was 96%. Then, the discriminant model was used to judge the water source of the sudden（surge） water in the roadway excavation of the F6206 working face, and the accuracy of the discrimination reached 90%. The model established this time provides an effective method for discriminating water inrush from the Buliangou Coal Mine.
