Mastering the characteristics and functional suitability of mine water is a prerequisite for achieving resource utilization and graded utilization of mine water sources. Taking the mine water in Yushuling Coal Mine as the research object, water samples were collected from different areas for water testing, the types of mine water resource utilization were divided, an evaluation system was established, and the functional suitability of different utilization directions of mine water was comprehensively analyzed. Research results show that the chemical type of mine water is mainly , with a membership degree of 0.812 - 0.991 for Class V water. The content of hydrochemical components is high, and there are three potential utilization pathways for drinking, irrigation, and industrial water. The suitability evaluation results of various types of mine water for drinking are grade Ⅲ and Ⅳ, which are not suitable for drinking.In terms of irrigation and industrial water suitability, there are significant differences in the evaluation results of different types of mine water. The sodium adsorption ratio, Razner stability index of water accumulation in goaf and fissure water are 3 - 10.8 (mmol·L)1/2and 6.1 - 6.5, respectively, indicating that they have little impacts on soil physical and chemical properties and are basically non-corrosive, making them suitable for irrigation and industrial water use. The saturation index of accumulated water in the burnt area is 0.8 - 1.2, exceeding 0.6, indicating a tendency towards scaling. Generally, it cannot be directly used as irrigation water, but can be used for industrial water use. The water quality of the water tank is severely polluted, with indicators such as soluble sodium percentage (78.4% - 84.5%), magnesium hazard ratio (62.9% - 72.0%), Razner stability index(7.2 - 7.7), and Larson ratio (8.0 - 12.0), indicating that this type of water poses a high risk to soil alkalinity and permeability, and has severe corrosiveness, with poor potential for functional utilization.
