The invention discloses a mining solid waste-based grouting material and a preparation method thereof, and belongs to the technical field of mining grouting materials and solid waste resource utilization. The grouting material is prepared from the following components in parts by weight: 10 parts of rice hull ash, 30-60 parts of fly ash, 30-60 parts of slag, 20-50 parts of 0.5-3mm river sand, 4-8 parts of NaOH particles and 1.6 parts of water glass modulus, and the grouting material can be prepared by uniformly mixing and stirring a cementing material and then pouring a mixed solution of NaOH, water and water glass. According to the invention, the solid waste-based material is utilized, so that the pollution to the environment is reduced, the recycling of solid wastes is improved to the greatest extent, and the river sand is adopted as the aggregate, so that the compactness, the strength and the impermeability of the grouting material are improved, and finally, the mining grouting material which is good in fluidity, short in setting time and high in early strength is prepared. The material can be applied to the field of water bursting of mines, and has certain practical significance.
一种矿用固废基注浆材料及其制备方法，属于矿用注浆材料和固体废弃物资源化利用技术领域。注浆材料按照重量份计为：稻壳灰10份、粉煤灰30～60份、矿渣30～60份、0.5～3mm的河沙20～50份、NaOH颗粒4～8份，水玻璃模数1.6份，将胶凝材料混合搅拌均匀，再倒入NaOH、水和水玻璃混合溶液，可制得注浆材料。本发明利用固废基材料减少了其对环境的污染以及最大限度提高了固体废弃物的再利用，并且采用河沙作为骨料，提高了注浆材料的密实度、强度以及抗渗性，最终制备出流动性好、凝结时间短、早期强度高的矿用注浆材料。该材料可应用到矿山的涌水领域，具有一定的实用意义。
