文章结合程庄煤矿采区上山的无极绳绞车辅助运输改造为主要运输系统的实际，论证了在无极绳绞车运输系统中，若重车向下运输，绞车安装在斜巷上部可避免主轮松绳、摞绳、咬绳及尾轮、老轮跳绳引起矿车掉道现象，确保运输系统的合理性、可靠性和经济性。 Combining with the fact that the auxiliary transport of the convoluted rope winch uplift in Chengzhuang Coal Mine is transformed into the main transport system, it is demonstrated that if the heavy truck is transported downward and the winch is installed in the upper part of the inclined lane, Ropes, levitation rope, bite ropes and tail wheels, the old round of rope skipping caused the phenomenon of the car to ensure that the transport system is reasonable, reliable and economical.
