摘要:

探讨选煤厂拣矸作业中危险姿势对工人肌肉骨骼损伤的影响。通过问卷调查和工作姿势分析系统(OWAS)对工人不良作业姿势重复出现的比例以及身体损伤状况进行评估与分析。结果显示工人背部和颈部出现不良作业姿势的比例、危害和损伤程度较高。这与疲劳自觉症状调查和OWAS系统分析所得出的结果基本一致。采取恰当的轮岗方式,增加座椅以及防护装备可有效降低工人肌肉骨骼的损伤程度,同时会更好的提高工作表现并减少工伤事故的发生。

Abstract:

The effects of dangerous postures on workers musculoskeletal injuries in coal preparation plants during dirt extraction are discussed. By questionnaire survey and Ovako working posture analysis system (OWAS), the proportion of workers repeated harmful postures and physical damages are assessed and analyzed. The result shows that proportion and degree of harmful postures on workers back and neck are much higher, which is consistent with the result of fatigue selfconscious symptom survey and OWAS system analysis. Taking proper work shifts and increasing seats and protective devices may lower degree of workers musculoskeletal injury, improve performance in the workplace and reduce the occupational injuries and accidents.
