针对地下金属矿山人机系统的复杂性和动态性,基于人、机、环境、管理和信息5类事故致因,充分考虑各个因素之间的交互作用,确定地下金属矿山人机系统安全的15个重要影响因素,结合决策实验室分析法和解释结构模型对影响因素进行处理和分析,实现影响因素的层次划分.结果表明:人机系统中,人员各方面的知识更新慢和认知缺陷是根本原因;安全文化薄弱和非功能性交互是深层次原因;不确定性、信息交互受阻和系统结构脆性属于过渡致因;人为失误、人机约束失效、重复或遗漏控制、物质交互受阻、能量交互受阻和应变能力差是事故的近邻致因;机械物理部件失效和无事故事件通报对金属矿山人机系统安全性的影响相对较弱.%Aiming at the complexity and dynamics of man-machine system in underground metal mine , the interaction be-tween various factors was considered based on five types of accident causes including man , machine, environment , manage-ment and information , and 15 important influencing factors for the safety of man-machine system in underground metal mine were determined .The influencing factors were processed and analyzed combining with the Decision Making Trial and Evalua -tion Laboratory (DEMATEL) and Interpretative Structural Modelling (ISM), so as to achieve the hierarchical division of the influencing factors .The results showed that in the man-machine system , the slow update of knowledge and cognitive defects in various aspects of personnel were the root causes , the weak safety culture and non-functional interaction were the underly-ing causes , the uncertainty , information interaction blocking and fragility of system structure were the transitional causes , the human error , man-machine constraint failure , repetitive or missing control , material interaction blocking , energy interaction blocking and weak strain capacity were the neighbouring causes of accident , while the failure of mechanical and physical components and the event notification without accident had relatively weak effect on the safety of man -machine system in un-derground metal mine .
