Research On Factors And Mechanisms Affecting The Collaborative Safety Behavior Of Human-Machine Cooperation In Coal Mines

Coal energy accounts for 60% of China’s primary energy consumption structure.By 2050,the proportion of coal in energy will still be over 50%.Coal safety is the cornerstone and stabilizer of China’s energy security.As the technological level of coal mine production gradually improves and the coal mine safety management system becomes increasingly perfect,the number of coal mine accidents and the million-ton death rate have gradually decreased,but the complexity of coal mine accidents is increasing.The coal mine mining system is a complex human-machine environmental management system that requires miners to collaborate with intelligent equipment to perform mixed tasks.The safety of human-machine cooperation is crucial to the safety of the entire system.The safety of the coal mine human-machine cooperation system is influenced by many factors.Clarifying the complexity,evolution laws,and operating mechanisms of the system is essential for preventing coal mine accidents.Based on task-technology fit theory and accident causation theory,this paper uses a combination of quantitative and qualitative analyses to identify the factors affecting the collaborative safety behavior of human-machine cooperation in coal mines and explore the interactions between these factors.On this basis,a system dynamics model of the collaborative safety behavior of human-machine cooperation in coal mines is constructed,and the mechanisms of the factors affecting the behavior are explored.Based on simulation results,guidance strategies are proposed.The main content and research conclusions of this paper are as follows:(1)Identify the factors affecting the collaborative safety behavior of human-machine cooperation in coal mines.Based on task-technology fit theory and accident causation theory,22 factors that affect the collaborative safety behavior of human-machine cooperation in coal mines are identified from five aspects: individual factors of miners,intelligent system factors,organizational management factors,group factors,and environmental factors.(2)Clarify the interactions between the factors affecting the collaborative safety behavior of human-machine cooperation in coal mines,and construct a system dynamics model of the behavior.Based on the tripartite interaction determinism,the cause-effect relationship between the factors is determined using the DEMATEL-ISM method,and a multi-level hierarchical interpretation structure model is constructed based on the results of the ISM analysis,dividing the factors affecting the safety of the coal mine system into five levels and clarifying the interaction path between the factors.Based on this,the causal loop diagram and stock flow diagram of the collaborative safety behavior of human-machine cooperation in coal mines are determined.(3)Explore the mechanisms of the factors affecting the collaborative safety behavior of human-machine cooperation in coal mines and propose guidance strategies.The simulation equations and related parameters of the collaborative safety behavior of human-machine cooperation in coal mines are determined.The mechanisms of the factors affecting the behavior are clarified through simulation of the initial model,and the mechanisms of the factors affecting the collaborative safety behavior of human-machine cooperation in coal mines are determined by intervening in the variables of the model.Finally,guidance strategies for improving the collaborative safety behavior of human-machine cooperation in coal mines are proposed based on the simulation results.
