矿井提升是采矿工艺中最重要的一环。在不增加基本投资和改造提升机结构的情况下，实现对端负荷值和记号变化的自适应控制与保护，可以提高提升设备的效率。目前，提升机限速器的工作原理是测定提升容器的实际速度，将其与井筒一定点上的给走速度比较，如果实际速度超过给走速?
Mine lifting is the most important part of the mining process. Without increasing the basic investment and upgrading the structure of the elevator, it is possible to improve the efficiency of the equipment by adaptively controlling and protecting the end load values and mark changes. At present, the working principle of the hoist speed limiter is to measure the actual speed of lifting the container, comparing it with the feeding speed at a certain point on the wellbore. If the actual speed exceeds the feeding speed?
