| 摘 要： | 翁泉沟硼铁矿原设计生产能力为200万t/a,远不能满足扩建后选矿厂处理能力的需求。结合翁泉沟硼铁矿开采现状,通过分析采场矿体赋存条件,在采场实施分期开采方法和陡帮开采技术,结果表明,技术实施后迅速提高了采场的生产能力,降低了初期生产剥采比,缩短了投资回收期。

| Abstract: | The original design production capacity of Wengquangou Paigeite Mine is 2 million t/a,which can not meet the demand for processing power of expanded concentrator.The boron status of stope ore body and the mining status of Wengquangou Paigeite Mine are analyzed,and then multistage mining methods and steep slope mining technology are implemented.The production capacity of the stope is rapidly increased,the initial stripping ratio of production is reduced,and the payback period is shortened. |

| Keywords: | Wengquangou Paigeite Mine production capacity multistage mining steep slope mining |
