(七)全尾矿泵压充填采矿法 为了减少尾矿对地表环境的污染和扩大充填料的来源,最近西德研究成功了高浓度全尾矿充填工艺。由于实现了高浓度料浆水力输送,充填料不必在采矿场脱水,既减少了水泥消耗,又提高了充填体的强度。 (VII) Full Tailings Pumping Filling and Mining Methods In order to reduce the pollution of the tailings to the surface environment and to expand the sources of filling materials, the West Germany study recently succeeded in filling the high-concentration tailings filling process. Due to the high concentration of slurry hydraulic transfer, the filling material does not have to be dewatered in the mining area, reducing both the cement consumption and the strength of the filling body.
