Study on the Hydrochemical Characteristics and Evolution Law of Taiyuan Formation Limestone Water under the Influence of Grouting with Fly Ash Cement: A Case Study in Gubei Coal Mine of Huainan, China

Water, Journal Year: 2024, Volume and Issue: 16(7), P. 971 - 971

Published: March 27, 2024

The hydrogeological conditions of Huainan Coalfield are complex. Taiyuan formation limestone water (Taihui water) in this area is a direct threat to the source 1# coal mining floor. In order prevent and control disasters, Gubei Coal Mine adopted ground high-pressure grouting with fly ash cement block hydraulic connection between aquifer Ordovician aquifer. However, injected slurry will destroy original hydrochemical balance Taihui change its characteristics. Taking influence 2# karst collapse column Beiyi as an example, total 25 samples were collected. characteristics evolution law before after studied via multivariate statistical method. research methods include constant index statistics, Piper diagram, correlation analysis, ion combination ratio, saturation analysis. results show that grouting, concentrations Na+ + K+, Ca2+, Mg2+, Cl− decrease, while SO42− HCO3− increase. average values PH TDS become larger. types more concentrated, mainly HCO3-Na Cl-Na. correlations conventional indicators decrease. According analysis dissolution, cation exchange, pyrite oxidation occur water, these effects enhanced grouting. dolomite, calcite, gypsum significantly reduced, rock salt slightly increased. conclusion study greatly affected by cement. Moreover, because contains lower calcium oxide content than ordinary Portland cement, effect on concentration resulting hydrogeochemical different. Therefore, treatment mine should be identified.
