[Abstract]:The fully mechanized top coal caving face in coal mine is a complex and changeable man-machine-environment system. Because of the shortcomings of human physiological, psychological and behavioral characteristics, the design defects and hidden dangers in operation of the machine itself, as well as the bad degree of the working environment and the uncertainty of geological conditions, these factors all cause accidents and affect production. By optimizing the three system elements of man, machine and environment and starting from the angle of system matching and coordination, it is an important way to realize safe and efficient mining in fully mechanized caving face.
On the basis of the theoretical study of man-machine-environment system engineering, safety psychology and ergonomics, this paper analyzes the three system elements of personnel, machine and environment in fully mechanized caving face of coal mine, and finally selects 9 personnel-related indexes, 6 machine-related indexes and 7 environment-related indexes which affect the safe and efficient mining of coal face. The systematic characteristics of fully mechanized caving face are analyzed from the angles of theory, coupling theory and entropy theory. It is pointed out that the system fusion of fully mechanized caving face refers to the dynamic relationship among the three systems of man, machine and environment, which coordinate and promote each other. The aim is to realize the safe and efficient mining of fully mechanized caving face through the system fusion. The concepts of capacity coupling degree model and system coordination degree in physics are introduced. The man-machine-environment system fusion degree model is introduced. According to this model, the compatibility of 61B3 working face in a mine in Shanxi Province is evaluated and analyzed. According to the evaluation results, technical and management measures are put forward from three aspects of personnel, machinery and equipment, and environment. Finally, the phase is verified. The improvement of meltdown is conducive to the safety and efficiency of production.
