与司机有关的因素年龄发生卸载点事故的司机年龄为19～62岁不等。图5所示为卸载点事故按年龄区分的百分比。带星号的曲线表示卸载点事故的司机年龄。卸载点事故的司机年龄分布与矿山汽车司机的年龄的正态分布非常一致。因此,运输汽图6运输汽车卸载点事故按司机工作年限区分的次数车司机年龄与发生卸载点事故可能性之间似乎没有什么关系。工作经验大部分卸载点事故与司机缺乏或没有操作运输汽车经验有关。图6所示为运输汽车卸载点事故按司机工作年龄限区分的次数。发生卸载点事故的运输汽车司机的平均工作年限为3.81年。但工龄不到1年的司机发生的事故占41%,其中工作年限不到1个月的占41%,不到6个月的占82%。显然,缺乏经验是造成卸载点事故的重要 Driver-related factors Age Driver unloading accident occurred 19 to 62 years old. Figure 5 shows the percentage of accident at unloading point by age. The asterisk curve indicates the driver’s age at the point of unloading. The age distribution of drivers at the point of unloading is very much in accordance with the normal distribution of the age of mine drivers. Therefore, it seems that there is no relationship between the number of car drivers and the probability of accident at unloading point. Work Experience Most of the unloading point accidents are related to drivers’ lack of or lack of experience in transporting the vehicle. Figure 6 shows the number of accidents at the unloading point of a transport car divided by the driver’s working age. The average length of service of transport drivers who had unloading accidents was 3.81 years. However, accidents involving less than one year’s drivers accounted for 41%, of which 41% worked less than one month and 82% in less than six months. Obviously, lack of experience is important for unloading accidents
