Safety management positive assessment approach

ABSTRACT At present, researches on the relationship between coal mine safety input and safety performance focus on the static description. Results of the assessment on these studies lack in follow-up and dynamic management. In this paper, based on the analysis of factors that have impacts on coal mine safety performance in the process of coal production, one model about the relationship between coal mine safety input and safety performance is established using a system dynamics approach. In the process of computer simulation, coal mine safety performance is dynamically forecast by changing the initial safety level value and safety input increase rate of factors which affect system safety performance. The results show that the safety level of coal mine enterprises in the early period influences the coal mine expectant safety performance. The safety level of human factors and management factors in the coal mine enterprises is a positive correlation of coal mine safety performance. These provide a theoretical basis for management decision-making.
