Slime water-based high-water filling slurry, preparation method and curing accelerating method
The invention discloses slime water-based high-water filling slurry, a preparation method and a curing accelerating method, and is suitable for the field of in-situ resource utilization of mine wastewater. The slime water-based high-water filling slurry comprises a cementing material and slime water, the mass percentage concentration of the cementing material is 14.87-24.12%, and the balance is slime water; wherein the cementing material is prepared from the following components in percentage by mass: 39.65 percent to 44.70 percent of sulphoaluminate cement, 35.24 percent to 42.35 percent of fired calcium sulfate hemihydrate, 7.60 percent to 9.31 percent of volcanic rock and 8.05 percent to 16.28 percent of a composite additive; and the slime water is subjected to ultrasonic-alkali synergistic treatment, and then the treated slime water is used for preparing the high-water filling slurry, so that the solidification rate of the slime water can be increased. The method is simple in steps and convenient to use, adopts an ultrasonic-alkali synergistic effect to activate the slime water, weakens the argillization effect of clay in the coal slime, increases the solidification rate of the slime water, and is less in bleeding.
本发明公开一种煤泥水基高水充填料浆、制备方法及加快固化方法,适用于矿山废水原位资源化利用领域。包含胶结材料和煤泥水,其中胶结材料的质量百分浓度为14.87%~24.12%,余量为煤泥水;胶结材料的各组分质量比为:硫铝酸盐水泥39.65%~44.70%,烧制半水硫酸钙35.24%~42.35%,火山岩7.60%~9.31%,复合添加剂8.05%~16.28%;通过超声‑碱协同处理煤泥水,之后使用处理后的煤泥水制备高水充填料浆即可增加煤泥水固化速率。其步骤简单,使用方便,采用超声波‑碱协同作用活化煤泥水方法,减弱煤泥中黏土的泥化作用,增加煤泥水固化速率,泌水少。
