摘　　要：由于下开式自动卸载扇形门箕斗具有卸载快、运行平稳、故障率低等诸多优点,很多矿井用这种箕斗替代了垂直闸门或其他卸载形式的箕斗。对于如何通过多项改造并举,争取改造的最佳效果;对于如何避免改造过程中遇到的诸如影响过卷距离等一些实际问题,结合改造实例进行了论述。对同类矿井的技术改造起到一定的参考和借鉴作用。The bottom of sector doors open automatically unloading coal scuttle has many advantages such as unloading fast ,stable operation, low failure. There are many coal mines use it to instead of vertical gate or other forms of coal unloading scuttle.This article exposits how to transform by multiterm transform to achieve the best results. As far as how to avoid the transformation process such as the impact of excessive volumes encountered in the distance and some other practical problems ,in this thesis will be discussed combined with modified examples.
