许多经济上合理的地下开采技术取决于放矿后充填空区来建立和维持一种安全工作的条件.为了达到这种目的,往充填料中加水泥作为一种胶结剂,使之形成一种水泥质的坚固充填料,这在技术上是可行的.充填生产关于利用有色金属冶炼废渣进行采场充填,育特爱斯亚(Mount Isa)矿山有限公司在这个领域中是先驱者.而且,它一直是利用细磨制粒铜反射炉废渣的主要用户.主要的目的就是为了降低波特兰水泥的用量.
Many economically justified subsurface mining techniques depend on the emptying of the post-ore draw-out area to establish and maintain a safe working condition.In order to do so, cement is added to the charge as a binder to form a It is technically feasible to fill in a cementitious, sturdy filling material. Filling Production With regard to the use of non-ferrous smelting waste for stope filling, Mount Isa Mines Ltd. is a pioneer in this area. Moreover, It has been a major user of fine pulverized copper reverb furnace slag for the main purpose of reducing the amount of Portland cement used.
