应用箕斗井回风的新构思

A NEW CONCEPT ON USING SKIP SHAFT FOR AIR RETURNING

本文论述了箕斗并与矿井通风的关系。提出用箕斗并回风，以解决令人棘手的主溜井卸矿硐室、地下破碎硐室、皮带道、粉矿清理巷等与箕斗井伴生的高尘作业点的通风问题。同时提出用箕斗井回风，不需密闭井塔楼，不污染井口工业场地，且对改善井口工作环境极为有利的新构思。

In this paper,the relation between skip shaft and mine ventilation is discussed. It is suggested to return air through skip shaft in order to solve the troublesome ventlation problem in high dust area near the skip shaft such as main dumping station chamber, underground crusher chamber,belt conveyer drift and fine removing drift. Meanwhile a new concept on using skip shaft for air returning is presented that need not seal the shaft tower, not onIy can't pollute shaft top area. But also can extremly help improve shaft top working environment-
