摘要
目的：探讨煤矿工伤事故发生的时间分布规律，以便采取相应预防对策。方法：选择平顶山矿务局有代表性的三个矿，对１０年间（１９８７．１．１～１９９６．１２．３１）的全部工伤职工作回顾性调查，以年份、季节、月份、班次和２４ｈ制时间为指标，分析其规律。结果：工伤事故在１９８７～１９９４年发生呈下降趋势，１９９５～１９９６年又有回升；一年中以秋季多发，月份大部分集中在７～１０月份；班次以中班工伤事故多发，且２４ｈ中９～１０点为事故发生高峰。结论：一年间秋季或７～１０月份、中班（尤其是９～１０点）工伤事故多发。
To study on the pattern of time distribution for the injury accidents in coal mines,in order to adopt proper countermeasures,a retrospective study on all injury accidents for ten years (1987.1.1￣1996.12.31) was carried out in three coal mines of Pingding Shan.Time distribution patterns were analysed according to the established indices of years,seasons,months,shifts and 24 hours in the time of day.The results showed that the injury accidents were declined over 1987￣1994,but raised during 1995￣1996.It was suggested that injury accidents were occurred mainly in autumn and middle shifts,especially 9￣10 hours in the morning.
