Study On The Intrinsic Safety Of Coal Mines Based On The 4M Theory

Coal mines are man-machine-environment composed systems with complex structure. Based on the theory of 4M (man,machine,environment,management), relevant elements of coal mines are studied , leading to feasible principles for application of the Intrinsic safety concept to coal mines.Based on the theory of human behavior, the causes of human errors and accident patterns were discussed, and identification techniques and control methods of human errors are studied, and the Man Assessment Index Model of Intrinsic safety is founded. Through the analysis and evaluation of human reliabilityon the basis of the Fuzzy Synthesis Analysis Method, the data of the working force in working face 601 of The No.1 HuangLin Coal Mine is investigated and analysed.Through ergonomics analysis and reliability analysis, Machine Assessment Index Model is founded, which is further adopted in the application of man-machine engineering theory to coal mines in order to assure the Intrinsic safety of machinery. The data on the machinery of working face 601 in the No.1 HuangLin Coal Mine was studied.The environment of coal mines, being classified as working environment and geological environment, is investigated to reveal the impacts put on by various factors of coal mines. By carrying out the analysis on factors of occupational safety, the Environment Assessment Index Model was founded, and the relevant measures for the Intrinsic safety of coal mine environment are put forward.Based on the principles of occupation health and safety management and the System of National Industrial Safety Management, the hazard identification, risk assessment and risk control in coal mines are studied, and the standards of hazard management and risk control measures are proposed. The Management Assessment Index Model covering the whole series of major influencial factors is founded. AHP method is applied to evaluate the culturial environment of intrinsic safety in coal mines, thus provides an important assistance in decision making.As the system of man-machine-environment-management being thoroughly studied, an overall Evaluation Index System of coal mines is put forward. With the theory of Back Propagation Neural Networks and the Wavelet Neural Networks, the Assessment Model is thus established. The research on the sustainable safety in the No.1 Hangling Coal Mine of Shaanxi Province leads to the establishment of the Intrinsic Safety Management System, and the the evaluation model verification.The concept of Intrinsic Safety in coal mines safety management is a new ideology, which will greatly promote the improvement of safety management and safety control standard in coal mines to build a safer and more productive industry.
