Abstract
A large number of accidents caused by goafs have great influence on the ecological environment and public safety. In order to assess the risk degrees of goafs, a hybrid Tomada de Decisao Interativa Multicriterio (TODIM) method is proposed in this paper. Firstly, on account of the geological conditions, shape parameters and environmental factors, an evaluation index system is established. This system includes seven quantitative sub-criteria and six qualitative sub-criteria. The combined weight of each index is determined on the basis of game theory by combining the subjective weight and objective weight. Afterward, a fuzzy-TODIM method is put forward to obtain the rank of risk degree and the specific risk level. Finally, the hybrid TODIM method is used to assess the risk degrees of goafs in Shuikoushan lead-zinc mine under uncertainty. Sensitivity analysis is demonstrated to reveal the robustness of this approach. Results show that the proposed hybrid TODIM method can be adopted to assess the risk degrees of goafs reliably and stably.
