措施井延深竖井在大柳行金矿的应用

山东省蓬莱市大柳行金矿根据矿山生产需要及现状，经过对比论证，首次设计实施了在最大限度不停产的情况下进行竖井延深，即利用措施井进行下向竖井延深，最后实施与原竖井贯通。应用取得了显著的效益和良好的效果，使该井口生产能力扩大一倍，既满足了矿山生产需要，又增加了矿山后续生产能力。为矿山竖井开拓延深提供了一条可借鉴的经验。

Application of the deepened shaft based on stepping shaft in Daliuhang Gold Mine

Based on the situation and requirement of mine production,deepening shaft had been designed and made while production was,to the largest estent,not stopped.i.e.the shaft was deepened and interconnected by stepping shaft.The obvious benefit and good effect had been received by using this method.The productive ability of shaft incresased twice times than before.This measure met need of mine production and enhanced the production ability mine,simultaneously,provided an experience that can be used as an example in digging and deepening of shaft for mine.
