摘要
Abstract
To study the effect of different wet dry cycles on the hydrochemical characteristics of fractured sandstone,a water rock interaction experiment was conducted on the 10203 working face of Baozigou Mine as an example.The research results indicate that as the number of wet and dry cycles increases,the displacement of anions and cations in mine water is enhanced.Na++K+,HCO3-,and CO32-show a positive correlation trend,while Ca2+is the opposite.The dissolution precipitation effect of feldspar minerals is enhanced,and the chemical type of mine water gradually transforms from SO4-Ca to HCO3-Na type.The research results can provide reference for the hydrochemical evaluation of goaf in abandoned mine construction of pumped storage power stations.关键词
