煤矿生产系统中,如斜井和平巷的皮带机运输系统、地面生产系统、选煤厂生产系统等都是多台设备的连续运输系统,它们对控制的共同要求是: 1、逆煤流延时2～5秒顺序起车,有的系统还要求顺煤流顺序延时起车,延时时间T≤L/V(T—延时时间、L—皮带机长度、V—煤流速度); Coal mine production system, such as inclined shaft and lane conveyor belt conveyor system, ground production systems, coal preparation plant production systems are more than one continuous transport system equipment, and their common control requirements are: 1, reverse flow of coal 2 to 5 seconds when the order of the car, and some systems also require sequential coal flow delayed start, the delay time T ≤ L / V (T-delay time, L-belt length, V-coal flow velocity) ;
