Based on the exploration phase and geological data in the process of production in Gunagzhuang Mine, the lithology characteristics of the 10th coal floor was analyzed and evaluated as well as coal floor rock lithology types was divided. Statistics and analysis of plane deformation coefficient and fracture fractal dimension values, were used to divide the 10th coal floor rock mass structure type based on the grey and fuzzy evaluation method. Composite floor lithology and structural classification of floor rock mass stability can be divided into four categories, which provided scientific basis for the prevention and control of the mine floor water.
