In order to examine the extension theory in the application of soil and water loss severity partition, aiming at the complexity of the slope soil erosion in mines, and establishing a scientific and rational evaluation index system of slope soil and water loss on the basis of the analytic hierarchy process (AHP) and extension evaluation method, we established the severity assessment matter-element model of soil and water loss. According to each influence factor, the discriminant matrix of analytic hierarchy was established, the weight of each factor and the effect was concluded. Different parts of the soil and water loss problem were taken as an example in Jiaozuo City in He’nan Province. On the analysis of the seven factors affecting soil erosion in the study region and on the basis of harmful consequences, the slope soil erosion severity partition evaluation index and classification standard were proposed. Results showed that the soil erosion intensity classification result of Ministry of Water Resources was consistent with the method of the grading results, extension evaluation method based on hierarchical analysis applied to the soil and water loss severity partition was feasible, and could reflect the impact on the region soil and water loss of slope degree well. It was the first time that the hierarchy analysis and extension theory was applied to the severity of soil erosion assessment, which provided the new analysis method for the study of the soil and water loss danger division.
