Analysis of Deep Groundwater Source in Huibaoling Deposit Based on Hydrochemistry and Strontium Isotope Characteristics
摘要
Abstract
In order to reveal the source and evolution process of groundwater recharge in the deep part of Huibaoling iron deposit and better guide the prevention and control of water hazards in the mine,by using a combination analysis method of hydrochemical types,strontium isotope content and groundwater Durov diagram,87Sr/86Sr and Sr2+content relationship diagram,rMg2+/(rMg2++rCa2+)and Sr2+content rela-tionship diagram,the source of groundwater recharge,the formation mechanism of hydrochemical compo-nents and the evolution process of water rock interaction in the deep part of the mine have been revealled.It is indicated that the runoff characteristics of deep fissure water are mainly composed of silicate aluminum salt rock(metamorphic rock).Its runoff is slow in metamorphic rock formations,and its dissolution and filtration processes are fully carried out.Unlike the runoff characteristics of limestone and silicate alumi-num salt rock(mudstone sandstone)displayed by shallow fissure water and karst fissure water,it is weakly replenished by shallow groundwater in the upper part and is mainly composed of static groundwa-ter.Fault water is mainly supplied by sedimentary rock groundwater(shallow fissure water and karst fis-sure water)in the upper part,and has the same water rock interaction as deep fissure water when flowing along the fault fracture zone.关键词
