适应新采矿方法的需要提高充填体质量

富家矿原应用的采矿方法是电耙出矿的胶结充填法,随着开采深度的增加,原来的采矿方法出现了采场出矿效率降低、损失贫化增大、劳动强度加重、选矿技术指标下降等问题.为此,采用了铲运机出矿的高分层胶结充填法.但是,新方法对充填体强度要求增高.因此,经过多方实验,使充填体强度大为改善.

In order to meet the needs of new mining method and to enhance the qualities of stuff material filling physique

Primary mining method which is applied in mine of FuJia is the scraper goes out of the mine and glued fills the law . Along with the increasing of mining depth, the original problems that the mining method has originally appeared also the stop to reduce the mine efficiency and the enlarge of the loss dilution and the more heavier of labour intensity and the descend of the dressing technology quota. So the high layering used the scraper to go out the mine the gluedly fills the law. But the new method requires higher about filling the aspect intensity. Therefore after many ways of the experiments, the stuff material intensity improves greatly.
