1、外文资料与中文翻译外文资料：Safety Analysis on Fully Mechanized Mining FaceLiyun WUYuzhong YANGSchool of Energy Science & Engineering,Henan Polytechnic University,Jiaozuo,454003,Henan,ChinaAbstract：The safety of fully mechanized mining face was analyzed with man-machine-environment system engineering theory and m
2、ethodologyThe causes and countermeasures of human errors are put forwardThe relationship between casualty accident and workersstuff and fatigue is analyzedCasualty accident is analyzed qualitatively and quantitatively using ETA and FTA methodsGrey correlative analysis and fuzzy cluster analysis are
3、used to analyze environment factorsFinally, the safety of fully mechanized mining face in Xinzhuang coal mine is evaluated with grey entropy synthetic evaluation modelThe problems existing in fully mechanized mining face are pointed outKeywords：safety analysis; man-machine-environment system enginee
4、ring; fully mechanized mining face1IntroductionMan-Machine-Environment System Engineering is a new and developing comprehensive frontier science which came into being at the beginning of 1980sIt analyzes and researches man, machine, environment of the system, which are the three main factors in the
5、system, and their relationship between them so that the whole system is in the condition of safety and high efficiency in the light of systemFully mechanized mining has been the mainstream technology in coal mining for the sake of its safety and high efficiency with the advancement of science and te
6、chnologyAt the same time, it is also the approach for coal mines to enhance its output and economic benefitHowever, the underground working face accidents happen frequently1,which has heavily affected and restricted the safety and the production of coal minesAs a result, it is significant to deeply
7、research and analyze the safety of man-machine-environment system in fully mechanization mining face2Analysis of human factorMan is the main body, the key to create wealth and to attain the aim in the man-machine-environment systemOn the other hand, man is also the main factor to induce accidentsThe
8、 combination of mans unsafe behavior and unsafe machinery that is usually formed by man induces accident to happen21Causes of human errors and control of them211causes of human errorsThe author considers that a human error means the man didnt finish the prescriptive function or didnt finish the pres
9、criptive function in time under the prescriptive conditionsAs a result, man, machine or environment of the system suffers loss to some extentThe following causes inducing human errors are analyzed through investigating some coal mines(1)Safety awareness is so dim that workers usually act against rul
10、es(2)Character of workers is giddy-brained(3)Physiological factorSome weaknesses of human in physiology are the root of human errors(4)Mental obstacle(5)Stuff of workers is low(6)FatigueUnusual state and other special conditions(7)Defects of machine(8)Environmental factors212Control of human errorsO
11、n the basis of analyzing and grasping the causes of human errors, we can take some countermeasures to decrease human errorsFirstly, the safety management system, which takes man as the center, should be establishedSecondly, on the basis of management system, it is important to make man safetyThese c
12、ountermeasures mainly include safety law education, safety knowledge education, safety skill education, safety idea education, typical accident education, biorhythm and safety measuresThirdly, all works should be standardFourthly, working environment should be improved greatlyFifthly, it is importan
