摘要
为快速、准确地判别矿井突水来源,给矿井水害防治措施的制定提供依据,迫切需要对矿区内地下水的水化学特征有一个清晰的认识。以永陇矿区麟游区为例,通过对区内不同基岩含水层以往水质资料的整理分析,应用Piper三线图法对白垩系含水层和侏罗系含水层水的水化学特征进行了研究,获得了不同含水层水的水化学特征库。利用麟游区水化学特征库,对区内不同矿井的涌突水来源进行了判别,并用系统聚类分析法对判别结果进行了验证。结果表明,所建立的水化学特征库能够较好地对研究区矿井涌突水源进行识别,认为A矿涌突水来源为侏罗系含水层;B矿第一次涌突水来源主要为侏罗系含水层,且有部分白垩系含水层水参与,第二次涌突水来源为侏罗系含水层。识别结果与实际相符,可为永陇矿区相邻矿井提供借鉴。
To fast and exactly discriminate mine water bursting water source,provide basis for mine water hazard control measures draw up,thus urgently needed to have a clear understanding on mine area groundwater hydrochemical features.Taking the Linyou region in Yonglong mining area as an example,through different bedrock aquifers previous water quality data sorting and analysis,using the Piper trilinear nomograph has carried out discrimination between hydrochemical features of Cretaceous aquifers and Jurassic aquifers.Thus have established different aquifer hydrochemical features library.Using acquired Linyou region hydrochemical features library has carried out discrimination for different mine water bursting water sources,then through systematic cluster analysis carried out discriminated results verification.The result has shown that the hydrochemical features library can distinguish study area water bursting water sources better.It is considered that the mine A water bursting water source is from Jurassic aquifers;while the mine B first water bursting water source is mainly from Jurassic aquifers,but a part of Cretaceous aquifers water participated in,while second water bursting water source is all from Jurassic aquifers.Discriminated results are consistent with practical situation,thus can provide reference for Yonglong mining area neighboring mines.
