Novel expansion filling material and preparation method thereof
The invention relates to a novel expansion filling material and a preparation method thereof, and the novel expansion filling material comprises the following main components: a cementing material, mine tailings, a foaming agent, an expanding agent, an accelerator and a stabilizer. The novel expansion filling material comprises the following specific components in percentage by mass: 14.51%-14.82% of a cementing material, 58.05%-59.28% of mine tailings, 23.24%-23.53% of filling water, 1.74%-2.83% of a foaming agent, 0%-1.45% of an expanding agent, 0.44% of an accelerator and 0.15% of a stabilizer, wherein the cementing material is preferably one or more than one of ordinary Portland cement and Portland slag cement (cementing powder). The novel expansion filling material and the preparation method have the beneficial effects that the novel expansion filling material is ideal in strength, short in expansion development time and high in volume expansion rate, and can actively contact a roof, effectively improve the roof contact rate, improve the roof contact effect and improve the stope stability.
本发明涉及一种新型膨胀充填材料及制备方法，新型膨胀充填材料由以下主要成份组成：胶凝材料、矿山尾砂、发泡剂、膨胀剂、速凝剂和稳定剂，所述新型膨胀充填材料具体成分及质量比为：胶凝材料14.51%～14.82％、矿山尾砂58.05%～59.28％、充填用水23.24％～23.53％、发泡剂1.74%～2.83%、膨胀剂0％～1.45％、速凝剂0.44%、稳定剂0.15％，所述胶凝材料优选为普通硅酸盐水泥和矿渣硅酸盐水泥（胶固粉）一种或一种以上。本发明的有益效果是：该新型膨胀充填材料及制备方法，本发明的新型膨胀充填材料强度理想、膨胀发育时间短、体积膨胀率大，能够主动接顶，有效提高接顶率，改善接顶效果，提高采场稳定性。
