为有效控制矿工的疲劳度，降低人因事故的发生；研究采用扎根理论构建矿工体力疲劳影响因素指标体系，并开发影响矿工体力疲劳的调查问卷；依托调查问卷的数据，运用熵值定权法探究各指标对矿工体力疲劳的影响程度，提出相应安全管理提升策略；并应用TOPSIS模型对随机选取的15名矿工开展体力疲劳综合评价。结果表明：矿工体力疲劳主要受自身状况、工作压力和作业环境3个因素影响，其中工作压力所占权重最大；矿工体力疲劳TOPSIS综合评级模型可合理有效地研判矿工体力疲劳程度等级。

In order to effectively control the occurrence of human accidents caused by physical fatigue of miners, in this study, grounded theory is used to construct the index system of influencing factors of miners’ physical fatigue and the questionnaire of miners’ physical fatigue is developed; based on the data of the questionnaire, entropy weighting method is used to explore the influence degree of each index on miners’ physical fatigue, and put forward corresponding safety management promotion strategies; and TOPSIS model is applied to evaluate the physical fatigue of 15 miners randomly selected. The results show that: the physical fatigue of miners is affected by their own condition, work pressure and work environment, among which work pressure is the most important factor; the TOPSIS comprehensive rating model of miners’ physical fatigue can judge the grade of miners’ physical fatigue reasonably and effectively.
