goaf slopeimproved TOPSIS methodevaluation indexsafety evaluation
Accurately evaluation safety performance of goaf slope was of great significance to ensure mine production safety. In order to solve problems of tedious and low accuracy in the safety evaluating of goaf slope, TOPSIS theory was used to establish evaluation model. Firstly, the uncertainties and correlations of influencing factors were considered, and HHM method was adopted to construct a multi-level evaluation index structure system from aspects of the disaster-prevention environment, hazard-causing factors and disaster-bearing bodies. Then the coefficient of variation method was introduced to improve the TOPSIS and to remedy errors which caused by the problem of reverse order phenomenon. After that, the safety grades of goaf slope were divided and quantitative interval of safety grades judgment was constructed by relative closeness degree. Finally, the established model was applied to verify in the engineering project, and compared with the results of common evaluation methods. The research results show that the evaluation model is in good consistent with the actual goaf slope engineering state, and with high accuracy and rationality. The model provides a new and reliable method for identifying safety performance of goaf slopes and timely scientific managing slope disasters.
