Abstract: Aimed at the problem of mine refuge station location, evaluation model of mine refuge station location design scheme was established by using DHGF algorithm. A new comprehensive integrated assessment method of mine refuge station location design which combined with qualitative and quantitative analysis, was proposed according to grey theory and fuzzy mathematics.In this paper, based on the introduction of fundamentals and evaluation process of this new assessment method, a case study on assessment of coal mine refuge station location design scheme in Datun Kongzhuang Coal Mine of China Coal Group was presented. The optimal and risk-minimizing design scheme was obtained from the case.
