The Research Of Intrinsic Safety In Man-Machine-Environment System Of Coal Mine

Comprehensive evaluation of intrinsic safety for coal mine is to achieve the intrinsicsafety for coal mine. The complexity of the production system of coal mine decides thatsafety evaluation of coal mine is a complex systemic project, so the right-constructed,reasonable and effective evaluation index system of intrinsic safety for coal mine is veryimportant.This thesis takes the coal mine safety as the main purpose and takes the mine'sman-machine-environment system as the object of study. The safety factors ofman-machine-environment system have been systematically analyzed. Based on humanbehavioral theory, the reasons of human error and the accident modes resulted from humanerror are discussed, the ergonomics analysis and the reliability analysis of the machines aredone, the influences of special underground environmental elements are analyzed, themeasures and methods of achieving the intrinsic safety for underground environment in mineare studied.On the basis of the analyzing the present safety assessment index system and combiningwith the coal mine facts, the safety assessment index system of mine is established. The indexsystem is composed by 4 first-grade index, 16 second-grade index and 53 third-grade index.Using Fuzzy Borda Method Based on Grid Acquisition Model to confirm the first gradeindicator weights. The weights of the Second and third grade indicator are estimated byAnalytic Hierarchy Process.On the basis of the present safety assessment method, the mine fuzzy comprehensiveassessment model is established, and it has been carried on practical coal mine. Then, thisevaluation index system has been applied to evaluate the intrinsic safety of coal mine, and weget that this coal mine grade of intrinsic safety. And then we give the measure about the constrution of intrinsic safety of coal mine on the basis of evaluation.
