摘要
采用水泥作为矿山充填胶结材料 ,充填成本高。本项研究以氟石膏为粉煤灰的胶溶剂和激发剂 ,解决了长期以来粉煤灰固化速度慢的问题 ,并以此为基础 ,试验成功了一种新型充填胶结料。它具有粉煤灰用量大、成本低。
The backfilling cost is high if cement is used as a cemented material. In this study, the problem of slow solidifying speed of fly ash has been solved by using fluorogypsum as peptizing agent and activator of fly ash On the basis of the study result, a new type of cemented backfilling material has been successfully developed This material has the advantages of more fly ash demand, lower cost, higher strength of later stage
