摘要
快速识别充水水源是解决及预防矿井水害事故的关键工作之一。文章根据淮南潘三井田内不同含水层水化学成分存在的差异,选取8种水化学指标作为判别突水水源的样本变量,对其进行常规水质分析,并利用Piper三线图来揭示突水点水样与井田内各含水层水化学特征,然后运用独立性权系数对含水层水质指标进行赋权,最后通过灰色关联度理论对样本数据进行水源识别,得出突水水源为13-1煤顶板砂岩裂隙水。结果表明:piper三线图可很好地分析各含水层的水化学性质,独立性权-灰色关联度理论可以避免指标信息重复并排除相关干扰因素,能够精确识别突水水源,从而为矿井突水水源的识别提供一种新方法。
In order to solve and prevent mine water accident, it is one of the key tasks to quickly identify- the water inrush somse. Based on the difference in chemical compositions of groundwater in different aquifers in the Pansan mine in Huainan, eight kinds of hydrochemical indexes are selected as the sample variables to judge the water inrush source. They are analyzed by routine water quality analyses. The Piper diagram is used to reveal the water inrush points and well fields and the independent weight coefficient is use to empower the aquifer water quality indicators. The water somve identification of the sample data is carried out by the gray relational degree theory. The results show that the inrush water somve is the groundwater from the 13-1 coal roof fissured sandstone. The piper diagram can perfectly indicate the hydrochemical properties of the aquifers. The independent weight-gray relational theot'y can avoid the repetition of indicators and eliminate the relevant interference factors, and can accurately identify the water inrush somve. It can provide a new method for the identification of water inrush source.
