The Coal Mine Intrinsic Safety Assessment Model Established and Application Based on the Theory of BP Neural Networks

摘要

Coal mines are man-machine-environment composed systems with complex structure. Based on the theory of man-machine-environment-management, relevant elements of coal mines are studied, which leads to feasible principles for application of the intrinsic safety concept to coal mines. Based on the theory of human behavior, the Man Assessment Index Model of Intrinsic safety is founded; through ergonomics analysis and reliability analysis, Machine Assessment Index Model is founded; the environment of coal mines, being classified as working environment and geological environment, the Environment Assessment Index Model is founded; based on the principles of occupation health and safety management and the System of National Industrial Safety Management, the Management Assessment Index Model is founded. As the system of man-machine-environment-management is thoroughly studied, an overall Evaluation Index System of coal mines is put forward. With the theory of Back Propagation Neural Networks, the Assessment Model is thus established. The research on the sustainable safety in a certain Coal Mine of Shaanxi Province leads to the establishment of the Intrinsic Safety Management System, and the evaluation model verification. The concept of Intrinsic Safety in coal mines safety management will greatly promote the improvement of safety management and safety control standard in coal mines and build a safer and more productive industry.
