Large-volume muck high-flow-state filling material and preparation method thereof
The invention discloses a large-volume muck high-flow-state filling material and a preparation method thereof, and the large-volume muck high-flow-state filling material is prepared from the following components in parts by mass: 8 to 10 parts of sulfate cement, 80 to 100 parts of muck, 16 to 20 parts of fly ash, 0.2 to 0.4 part of sodium tripolyphosphate, 0.4 to 0.5 part of lauryl sodium sulfate, 0.3 to 0.4 part of 2-ethylhexyl phosphoric acid-2-ethylhexyl ester, 0.2 to 0.3 part of nanoscale bubbles, 0.1 to 0.2 part of polyacrylamide, 0.6 to 0.9 part of calcium formate and 12 to 18 parts of water. The filling material is good in fluidity, and efficient and low-cost filling of the goaf is achieved.
本发明公开了一种大掺量渣土高流态充填材料及其制备方法，按质量份计，由以下组分组成：硫酸盐水泥8～10份，渣土80～100份，粉煤灰16～20份，三聚磷酸钠0.2～0.4份，十二烷硫酸钠0.4～0.5份，2‑乙基己基磷酸‑2‑乙基己基酯0.3～0.4份，纳米级气泡0.2～0.3份，聚丙烯酰胺0.1～0.2份，甲酸钙0.6～0.9份，水12～18份。该充填材料流动性好，实现了采空区高效低成本充填。
