摘要
本文对河台金矿采矿方法的实践作了回顾,肯定浅孔留矿法的长处,也指出了其不足。并建议改进回采工艺,加强对采空区的全面综合治理和压缩浅孔留矿法应用的比例,加大上向分层干式充填法的应用比例。
In this paper, it retrospects detail the practice of mining methods in He Tai Gold Mine, af-fuming the advantage of short- hole shrinkage stopping, and pointing out its shortcoming. It also suggests improving stoping art strengthen the comprehensive disposal of emptied stope and decrease the applied proportion of shrinkage stoping, enlarge the applition of the overhand cut - and - fill stoping methods with dry back - filling.
