摘　　要：在矿井生产过程中,机电事故经常会发生,但又是可以尽量避免发生的事故。由于生产管理科学化,人员素质不断提升,机电事故发生次数和致死人数也在不断的发生着变化。为分析煤矿事故中机电事故占比和机电事故致死人数占比多年来的变化情况,收集了31个矿井的数据,采用最小二乘拟合的方法进行分析。从分析结果可以看出机电事故数占整个事故数量的比重和机电事故致死人数占致死总人数的比都是呈现下降的趋势。In mine production process, mechanical and electrical accidents happened frequently which were avoidable. Frequency of mechanical and electrical accidents and number of deaths were constantly changing with the development of scientific production management and improving personnel quality. In order to analyze changing proportions of mechanical and electrical accidents and deaths numbers, information of 31 mines were collected and its data were analyzed by least square fitting method. From the analysis results we could see that these two proportions showed decreasing trend.
