Research On Coal Mine Lean Safety Management Based On System Dynamics

Improving the level of safety management and reducing or even eliminating production safety accidents in my country's coal industry are inevitable choices for the healthy development of China's coal industry.Therefore,based on related theories such as safety management,lean management,and system dynamics,carrying out coal mine lean safety management research has guiding and practical significance for promoting the improvement of coal mine safety management level.Guided by the methods and ideas of lean management,combined with the problem-solving ideas of system dynamics,the system dynamics is applied to the lean safety management of coal mines,and the basic theory and dynamic system of lean safety management based on system dynamics are studied.,The dynamic model of the lean coal mine safety management system was constructed,and the model was simulated.Based on the basic principles,method guidance and lean tools of lean management,on the basis of systematically analyzing the interrelationship and relationship between safety management and lean thinking,a system containing lean safety operation methods and lean safety management and control are proposed.The theoretical methods of lean coal mine safety management in three aspects:method system and lean safety culture method system;based on the three levels of coal mine safety management leadership,management,and operation levels,research and analysis of the lean safety management of coal mines The index system of each.influencing factor lays the foundation for the construction of the system dynamics model of lean safety management in coal mines;the relationship between the influencing factors of lean safety management in coal mines and the systematic and dynamic characteristics of lean safety management in coal mines are carried out.In-depth analysis;starting from the coal mine's own controllable factors,namely the three levels of leadership,management,and operation,as well as the interrelationship between the factors,the complex causal feedback relationship between the indicators of various influencing factors is analyzed,and leadership is constructed The causal feedback loop diagram of the coal mine,the management,and the operation layer,and the dynamic flow diagram of the lean safety management system of coal mines,collected various variables,and dynamically analyzed the effect of lean safety management in coal mines,and then obtained the influence of factors at different levels on the lean The degree of impact on the effectiveness of standardized safety management.Through simulation,we can intuitively describe the effect of lean safety management in coal mines and predict development trends;coal mines can also use the dynamic model of lean safety management system to conduct self-safety management evaluation,thereby improving the status quo of coal mine safety management and making lean coal mines.Safety management laid the theoretical foundation.
