摘要
为了研究不同轮班制度对煤矿井下一线矿工疲劳的影响,通过建立疲劳指数数学模型,以魏家地煤矿综放一队60名职工为研究对象,分2组进行"三八制"和"2×7+4制"轮班作业,应用疲劳指数评价法进行疲劳评析,得出2种不同轮班制度对职工疲劳程度的影响。结果表明,魏家地煤矿井下一线现行的"三八制"轮班制度对职工安全生产造成了一定程度的疲劳影响,存在一定的安全隐患,应建立合理的轮班制度,保障矿井安全发展。
In order to study the influence of different shift systems on front-line miner fatigue of underground coal mine,through the establishment of mathematical model of fatigue index,a team with 60 employees is taken as the research object in Weijiadi Coal Mine,the team is divided into two groups to carry on ＂ three eight-hour shifts＂ and ＂ two seven-hour plus four hours shifts ＂. We apply fatigue index evaluation method to carry ouy fatigue analysis,and obtain the influence of two different shift systems on staff fatigue degree. The results show that the current ＂ three eight-hour shifts＂ system causes a certain degree of fatigue effect to safe production of front-line workers in Weijiadi Coal Mine,and has a certain safety risk; we should establish a reasonable shift system to guarantee the safety of mine development.
