Hydrochemical and Hydrogen–Oxygen Isotope-Based Identification of Water Sources in Mine Wells

Mine gushing water disaster is one of the important factors affecting the safe production of coal mines, accurate identification of mine gushing water sources, the safe production of coal mines is a significant application. In this paper described, to identify the source of water filling in Tianxin coal mine, using Schukarev classification, Piper trilinear diagram, gray correlation degree, and hydrogen and oxygen isotopes for comprehensive analysis. The analysed results show that the water gushing in the mine of Tianxin coal mine mainly receives the influence of the water of Xiaobaiyang River and Quaternary loose rock pore diving water. However, the reliability of the results is improved by combining the hydrochemical analysis method with the analysis method based on mathematical theory. Identify the source of mine gushing water, and provide guidance for the prevention and control of mine water damage that may occur subsequently.
