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.
