摘要/Abstract

摘要： 为解决矿工工作强度大难度大,容易产生身体疲劳,引发不安全行为的问题,首先,向矿工发放肌肉疲劳调查问卷,了解矿工的实际工作状态;其次,利用表面肌电(EHG)试验模拟矿工作业环境和工作内容,检测其肌肉疲劳程度及变化特征;最后,结合矿工工作现状,提出肌肉疲劳事故的防控措施。结果表明:矿工的颈部、肩部、背部、肘部、腰部等部位肌肉疲劳的比例较高;肌电信号值与肌肉疲劳度呈负相关关系,建议矿工在疲劳失稳期前休息,以避免或延缓疲劳,减少不安全行为,降低人为事故率;矿工因肌肉疲劳引发事故的防控措施可以从工作时间预警、工作环境预警、综合预警档案及机械宜人化设计等方面进行。

Abstract: In order to solve problem of miners' work intensity and difficulty, it was easy to cause physical fatigue and lead to unsafe behavior. Firstly, questionnaire of muscle fatigue was issued to miners to understand actual working state of miners. Secondly, surface EMG test was used to simulate working environment and work content of miners, and degree and change characteristics of muscle fatigue were detected. Finally, combined with experimental results and working status of miners, prevention and control measures of muscle fatigue accidents were put forward. The results show that proportion of muscle fatigue in the neck, shoulder, back, elbow, waist and other parts of miners is high. It is suggested that miners should take a rest before fatigue instability period to avoid or delay fatigue, reduce unsafe behaviors and reduce rate of human accidents. Prevention and control measures of muscle fatigue accidents of miners can be carried out from aspects of working time early warning, working environment early warning, psychological stress warning, comprehensive early warning files and mechanical amenity design.

Key words: coal miners, muscle fatigue, surface electromyography(EMG), prevention and control measures, median frequency(MF)
