摘　　要：随着我国矿山绿色开采、资源循环经济战略的提出,"就近取材"成为矿山充填材料来源的首选。本文系统总结了国际首例全磷废料即磷石膏作为充填骨料,黄磷渣为胶凝剂的绿色充填理论与工艺。从材料的物化特性、流动性、强度时效性以及安全和环保的角度,探讨了全磷废料作为充填材料进行磷化工矿山充填的可行性,并在磷石膏环管试验结果的基础上,对原有的磷石膏充填工艺进行改造,提出了适应磷石膏物料特性的似膏体充填新模式,为我国磷化工企业矿山的绿色、安全和高效开采提供了示范。With the popularization of the concept of green mining and resource recycling economy strategy in China,“local material”has become the preference for backfill in mines.This paper systematically summarizes the green backfill theory and technology of the whole phosphorous waste(Phosphogypsum as aggregate and yellow phosphorus slag as binder)which was first proposed in the world.From the perspectives of physicochemical properties,flow characteristic,strength development,safety and environmental benefit,the feasibility of backfill with whole phosphorus wastes is discussed.On the basis of loop test,the original phosphogypsum backfill technology was replaced by a new cemented paste backfill technology,setting an example for green,safe and efficient mining for phosphorus chemical enterprises and mines in China.
