To grasp the characteristics and functional utilization suitability of mine water is the premise of realizing the resource treatment and classification utilization of mine water source. Taking Yushuling coal mine as the research object, various types of mine water were collected for water samples detection, the types of mine water resource utilization were divided, and an evaluation system was established to comprehensively analyze and evaluate the functional suitability of different utilization directions of mine water. The study shows that the chemical type of mine water is mainly SO2-4·Cl--Na+ type, the membership degree of V water is 0.812-0.991, and the content of water chemical components is high. There are three potential utilization ways of drinking water, irrigation water and industrial water. The suitability evaluation results of all kinds of mine water are grade Ⅲ and Ⅳ, which are not suitable for drinking. In terms of the suitability of irrigation and industrial water, the evaluation results of different types of mine water are quite different. The gob water, fissure water SAR[3-10.8 (mmol·L-1)1/2], RSI (6.1-6.5) and other indicators show that the impact on soil physical and chemical properties is small and basically non-corrosive, suitable for irrigation and industrial water, the fire area water LSI (0.8-1.2) > 0.6, with a tendency to scale. Generally, it cannot be directly used as irrigation water, but it can be used for industrial purposes. The water quality of the warehouse water is seriously polluted. The SSP (78.4-84.5%), MHR (62.9-72.0%), RSI (7.2-7.7), LR (8.0-12.0) and other indicators show that this type of water has high harm to soil alkalinity and permeability. And it has serious corrosion and poor functional utilization potential.
