露天运矿车粘底层的清理工作,是矿山运输作业的薄弱环节之一,据不完全统计,粘底层平均占运矿车容积的15％~30％。对粉矿比例大、含水量高、矿粉粘度高的矿山,这个问题尤为突出。露天运矿车粘底层的存在,不能充分发挥运矿车的装载效能,造成人力、物力及设备能力的浪 Open-pit car sticky ground cleaning work is one of the weak links in the mine transport operations, according to incomplete statistics, the bottom layer average occupy 15% to 30% of the transporter car volume. The problem is particularly acute for mines with a large proportion of fines, high water content and high viscosity of fines. Open-air transport car sticky bottom of the existence, can not fully exert the load carrying capacity of the car, resulting in human, material and equipment capabilities of the wave
