Abstract:Considering the little time delay impact of careless level on the safety level, a nonlinear dynamic evolution model about the careless and safety of the human-machine system with little time delay was built to explore the predisposing factors of frequent personal injury accident in the underground metal mining. And the validity of constructed model was well verified by the simulation results studied in the mathematical analysis and dynamic evolution of the dynamic evolution model. In addition, the qualitative analysis on nonlinear dynamic evolution and trend of safety with little time delay in the underground metal mining not only reveals the interaction evolution model of careless level and safety level in the four dynamic regions, but also provides basis for the safety evaluation and control of the human-machine safety system in the underground metal mining.
Key words: underground metal mining; little time delay; human-machine safety system; dynamic evolution mechanism
