小时滞影响下地下金属矿山人机安全系统动态演化机理辨析

Dynamic evolution mechanism analysis of human-machine safety system with little time delay in underground metal mining

为探索地下金属矿山开采过程中人身伤害事故频发的诱发因素,考虑马虎水平对安全水平的小时滞影响性,构建小时滞影响下地下金属矿山开采人机系统马虎性与安全性的非线性动态演化模型。对该演化模型所进行的数学分析和动态演化仿真研究结果较好地验证所构建模型的有效性,而对地下金属矿山开采人机安全非线性动态演化及其趋势定性分析不但揭示了4个动态区域内马虎水平与安全水平的相互作用演化模式,还可为地下金属矿山开采人机安全系统的安全评价与控制提供依据。

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.
