摘　　要：为了确定条带膏体充填法的合理膏体充填料,针对“粉煤灰+水泥”“粉煤灰+水泥+PA贝福剂”以及“粉煤灰+胶结料”3种模式的充填料浆,通过膏体流动性试验、泌水试验以及膏体强度试验,本着安全和经济的原则,确定使用“粉煤灰+水泥+PA贝福剂”的膏体充填材料,且确定了其合理的配比。现场应用表明,该种充填材料具有较好的技术效果和经济效益,值得推广。In order to determine the reasonable paste filling material for the strip paste filling method,in light of a paste filling material of“fly ash+cement”,“fly ash+cement+PA Bifurcation agent”,and“fly ash+binder”,through paste flowability test,bleeding test,and paste strength test,the paste filling material of“fly ash+cement+PA Beifu agent”was used based on the principles of safety and economy,and the reasonable ratio was determined.The on-site application shows that this type of filling material has good technical and economic benefits.
