| 摘 要： | 水泥—磷石膏浆体充填是现在矿山磷石膏胶结充填的主要方式,控制水泥用量是减少充填成本的最直接方法。文章提出用粘土作为水泥替代材料用于井下胶结充填,研究了材料配比、养护龄期、质量分数、添加剂掺量对于粘土—水泥—磷石膏充填体力学性能的影响,说明了粘土—水泥—磷石膏浆体充填具有应用价值。

| Abstract: | The cement-phosphogypsum slurry filling is the main way of the mine phosphogypsum cementation filling now,controlling the dosage of cement is the most direct method to reduce the cost of filling.This paper proposes that the clay as cement alternative materials is used for underground cementation filling,studies the performance of material ratio,curing time,concentration and additives admixture on the mechanical property of the clay-cement-phosphorous backfill,and explains that the clay-cement-phosphogypsum slurry filling has application value. |
