在使用翻斗式矿车的矿山矿车的损坏集中表现在车架断裂、车体铆接处开裂两方面。归结原因，多为矿车速度过快，互相碰撞所致。而矿山提升系统出车过程，大多采取空、重车自溜滑行，直至编组点的自选方式。它具有简便易行等优点，但由于坡度变化不易控制，导致车速过高，造成矿 In the use of dump truck mine car damage concentrated in the frame fracture, the riveting at the body cracking both. Attributed to the reasons, mostly for the car speed too fast, collide with each other. The mine to enhance the system out of the car process, most of them take empty, heavy truck glide, until the group point of choice. It has the advantages of simple and easy, but not easy to control because of the gradient, resulting in speed is too high, causing the mine
