Study On Safety Of The Man-machine-environment System Of The Fully Mechanized Coal Face

On the base of investigation in safety behaviour, the paper studied various typical safety behaviour modes in fully mechanized mining face and established worker's behaviour evaluation system. The reliability of machine in fully mechanized mining face was analyzed and the safety evaluation system of machine was established. The paper analysed the safety of geological conditions and working environment in fully mechanized mining face. The safety evaluation system of environment was established and measures to improve the environment's safety were given. For the optimization of the extraction's property, a measure system is designed. For optimizing the nozzle,12 different shells and 14 different rotators were designed and assembled in experiment. The LPDA (Laser Particle Dynamics Analyzer) test system is applied to analyze the properties of water particles sprayed by the five nozzles which fixed in the dust extractor. The model of safety training system in mines has been basically constructed. A software prototype was established for mining safety of man-machine-environment system.
