1、 1 外文资料与中文翻译 外文资料： Safety Analysis on Fully Mechanized Mining Face Liyun WU Yuzhong YANG School of Energy Science & Engineering,Henan Polytechnic University,Jiaozuo,454003,Henan,China Abstract： The safety of fully mechanized mining face was analyzed with man-machine-environment system engineering th
2、eory and methodology The causes and countermeasures of human errors are put forward The relationship between casualty accident and workersstuff and fatigue is analyzed Casualty accident is analyzed qualitatively and quantitatively using ETA and FTA methods Grey correlative analysis and fuzzy cluster
3、 analysis are used to analyze environment factors Finally, the safety of fully mechanized mining face in Xinzhuang coal mine is evaluated with grey entropy synthetic evaluation model The problems existing in fully mechanized mining face are pointed out Keywords： safety analysis； man-machine-environm

5、ree main factors in the system, and their relationship between them so that the whole system is in the condition of safety and high efficiency in the light of system Fully mechanized mining has been the mainstream technology in coal mining for the sake of its safety and high efficiency with the adva
6、ncement of science and technology At the same time, it is also the approach for coal mines to enhance its output and economic benefit However, the underground working face accidents happen frequently1,which has heavily affected and restricted the safety and the production of coal mines As a result,
7、it is significant to deeply research and analyze the safety of man-machine-environment system in fully mechanization mining face 2 Analysis of human factor Man is the main body, the key to create wealth and to attain the aim in the man-machine-environment system On the other hand, man is also the ma
8、in factor to induce accidents The combination of mans unsafe behavior and unsafe machinery that is usually formed by man induces accident to happen 2 1 Causes of human errors and control of them 2 1 1 causes of human errors The author considers that a human error means the man didnt finish the 3 pre
9、scriptive function or didnt finish the prescriptive function in time under the prescriptive conditions As a result, man, machine or environment of the system suffers loss to some extent The following causes inducing human errors are analyzed through investigating some coal mines (1)Safety awareness
10、is so dim that workers usually act against rules (2)Character of workers is giddy-brained (3)Physiological factor Some weaknesses of human in physiology are the root of human errors (4)Mental obstacle (5)Stuff of workers is low (6)Fatigue Unusual state and other special conditions (7)Defects of mach
11、ine (8)Environmental factors 2 1 2 Control of human errors On the basis of analyzing and grasping the causes of human errors, we can take some countermeasures to decrease human errors Firstly, the safety management system, which takes man as the center, should be established Secondly, on the basis o
12、f management system, it is important to make man safety These countermeasures mainly include safety law education, safety knowledge education, safety skill education, safety idea education, typical accident education, biorhythm and safety measures Thirdly, all works should be standard Fourthly, work
13、ing environment should be improved greatly Fifthly, it is important to design good interface for decreasing human errors Sixthly, safety culture should be spark plugged in enterprises 2 2 Analysis of human fuzzy reliability According to the theory of Hinesburg and Maslow, the hierarchy figure of human fuzzy reliability is established as Figure1
