矿车粘底是矿井运输中普遍存在的问题。它使矿车容积减少 ,运输效率降低 ,清理车底费工费时 ,劳动强度大 ,影响矿车的使用效率和使用年限。早在 70年代 ,煤炭系统的一些单位就因地制宜试制有多种形式的矿车清扫方法和设备 ,如 :电动高低频机械振动、电磁振动、风力振动、电渗法 Car sticking is a common problem in mine transportation. It reduces the volume of the tub, reduce transport efficiency, cleaning the bottom of the car when the labor costs, labor-intensive, affecting the efficiency and useful life of the tub. As early as the 1970s, some units of the coal system experimented with various methods and equipment for cleaning carts according to local conditions, such as electric high and low frequency mechanical vibration, electromagnetic vibration, wind vibration, electroosmosis
