摘要
介绍了河东金矿预控顶分段空场尾砂充填采矿法试验研究。结果表明,试验采场结构合理、生产能力大;采用预控顶措施,可以保证采场安全,降低矿石损失率和贫化率。
The experimental study of sublevel open stoping with tail filling and pre controlling of roof was introduced.It showed from experiment that by this mining method,the stope structure was reasonable with high produtivity,low rates of ore loss and impoverishment and the safety of stope can be guaranteed due to adopting measures of pre controlling of roof.
