刘桥一矿水文地球化学特征分析

The Study on Hydrogeochemistry of Liuqiao 1 Mine

刘桥一矿矿区地下水系统主要包括四个子系统:新生界松散层含水层组、二叠系煤系砂岩裂隙含水层组、以及石炭、奥陶系灰岩含水层组。而在该矿区的涌水来源主要为煤系砂岩水、太灰水以及奥灰水,因此从矿化度变化、硬度变化、水化学类型变化以及离子含量的特点等方面对这些主要含水层地下水的水文地球化学特征的研究,可以建立各个系统的水质模型,确定作为矿井涌水来源判别依据的水溶组分,进而给出矿井涌出水来源的水化学判别模式。

There are four subsystems in the underground water system: the Cenozoic loose layer, the aquifer group, the Permian coal measures sandstone fracture aquifer group, and the Carboniferous and Ordovician limestone aquifer group. In this area, the main water source for water, coal measures sandstone limestone water and Ordovician limestone water, therefore, from the changes of salinity and hardness change type of water chemistry change and the ion content of the characteristics of the main aquifer groundwater hydrogeochemical characteristics research, water quality model can be established for each system, determine as the mine water source discrimination criterion of wa-ter soluble components, water chemistry and give mine water determination mode source.
