中文摘要：

井工开采过程中面临着众多的不确定因素,各个因素相互影响,对井下安全生产有着十分重要的影响。为分析机电事故在近15 a间的变化规律和发生特点,统计了我国23个矿井的机电事故统计数据,采用最小二乘拟合的数学方法对统计数据进行分析。分析结果显示,机电事故发生造成的人员伤亡数和致死率都在呈现着下降的趋势。可以得出,我国煤炭生产的安全状况在不断的改善,多措并举促进安全生产的措施有效。

英文摘要：

There were many uncertain factors which influenced each other in underground mining, making a great difference in underground safety production. In order to analyze change rule and occurrence characteristic of electromechanical accident during the 15 years, statistic data of electromechanical accident in 23 mines of China were analyzed with the mathematical method of least square fitting. The results showed that the number of casualties and death rate caused by mechanical and electrical accidents was in a downward trend, which could draw a conclusion that measures we took were effective and safety situation of China＇s coal production was improving constantly.
