Abstract：With the gradual implementation of the concept of green mining technique in coal mines, more and more attention was paid to the influence of coal mining on groundwater. In this paper, the multivariate connection number of set pair analysis ( SPA) was used to describe the uncertainty and fuzzy uncertainty in the evaluation of coal mine water quality, and the interval triangular fuzzy numbers ( ITFN ) was introduced to describe the continuous change process of discrepancy degree coefficient of the structure of similar different antithetical of connection number, and a new decision evaluation model of interval triangular fuzzy numbers ( SPA-ITFN ) based on the multivariate connection number was finally put forward. Comparative analysis was carried out on the water quality in Yining Coal Ming Area, the evaluation results were consistent, and the size of connection number can reflect the degree of water quality pollution between the same levels. The calculation process of this model is simple and the result is objective and true, so it can provide a new method for evaluation of groundwater quality of coal mine and a technical support for scientific decision.
