摘要
石炭系太原组灰岩(简称“太灰”)地下水是潘集矿区煤层开采主要的充水水源之一。本研究收集了潘集矿区矿井水质数据,从地下水化学成分形成的角度,综合运用水化学含量指标分析、Piper三线图、离子组合比分析及相关性分析对潘集矿区石炭系太灰地下水进行水文地球化学类型分析。结果显示:研究区石炭系太灰水中阳离子主要为Na^(+)与Ca^(2+),阴离子主要为HCO_(3)^(-)与SO_(4)^(2-)。石炭系太灰地下水中发生的水岩相互作用主要包括碳酸盐和硅酸盐的溶滤溶解作用及Ca^(2+)与Na^(+)阳离子的交替吸附作用。研究结果可为潘谢地区地下水资源保护和煤炭开采管理提供参考。
The limestone groundwater of Carboniferous Taiyuan Formation(referred to as Carboniferous aquirfer)is one of the main water inrush sources for coal mining in Panji mining area.This paper analyzes the Carboniferous aquirfer in Panji mining area of Huainan coalfield,Anhui Province from the perspective of the formation of chemical components of groundwater,and comprehensively analyzes the hydrogeochemical types of Carboniferous Taihui groundwater in Panji mining area by using chemical index content analysis,Piper three line diagram,ion combination ratio analysis,correlation analysis,and groundwater chemical spatial distribution analysis.The results showed that the main cations of the carboniferous groundwater in this area are Na^(+) and Ca^(2+),and the main anions are HCO_(3)^(-) and SO_(4)^(2-).The main water-rock interaction in Carboniferous aquifer includes dissolution of carbonate and silicate,and cation alternating adsorption of Ca^(2+)and Na^(+).The research results can provide a reference for groundwater resources protection and coal mining management in Panxie area.
