摘要
为了安全、高效的开采鹰嘴山金矿宝贵矿产资源,首先对地下采场上盘坍塌原因进行了详细分析,在此基础上有针对性地开展了采矿方法及回采工艺研究工作。采用倾斜工作面框架结构干式充填采矿法取代普通干式充填采矿法,保证了回采作业的安全,提高了生产效率,降低了采矿损失和贫化。
In order to utilize the precious resources of Yingzuishan gold deposit safely and efficiently,the reasons of hanging wall rock collapsing are analyzed in detail,and the mining method and stopping technique are studied pertinently.The traditional dry back-filling method is replaced by inclined working face frame structure dry back-filling method.The new method ensures the mining safety,improves the production efficiency and reduces the loss and dilution ratio.
