Abstract： [Purposes] Aiming at the problem that the limestone water in the floor of No.1 coal seam in Huainan coalfield threatens the safe mining of coal seam，this paper takes the collapse column grouting project in the north No.1 mining area of Gubei Coal Mine as an example to study the influence of regional grouting on the chemical characteristics of limestone water.[Methods] Based on the hydrochemical data， thehydrochemical characteristics and causes of limestone water before and after grouting were studied bymeans ofconstant index statistics，Piper diagram，correlationanalysis，ion combination ratio，saturation index and principal component analysis.[Findings] The results show that after grouting，the average values of pH and TDS of the limestone water increase，while the concentrations of Ca2+ and Mg2+ and Cldecrease overall. The mass concentrations of Na ++K+ and So and HCO increase overall. [Conclusions]The research results provide a basis for the influence of regional grouting treatment project on mine groundwater resources and the protection of ecological environment resources in mining areas.
