All-tailing filling material and preparation method thereof
The invention relates to the technical field of mine filling, in particular to a full-tailing filling material and a preparation method thereof, and the full-tailing filling material is prepared from the following raw materials in parts by weight: 110-790 parts of full tailings, 0.5-1 part of cement, 8-12 parts of an auxiliary cementing material, 0.2-0.3 part of a strength exciting agent, 0.22-0.35 part of a micro-expansion additive and 52-546 parts of water. The full-tailing filling material provided by the invention has relatively high early strength and later strength, the volume of the material is slightly shrunk before and after hardening, the price is relatively low, the construction requirement is completely met, the full-tailing filling material can effectively improve the utilization of a large amount of tailing solid wastes and reduce the environmental pollution, and the full-tailing filling material has the advantages of safe mining, low cost and high economic benefit. The utilization rate of wastes is improved, and the environment-friendly mine filling material is obtained.
本发明涉及矿山充填技术领域，尤其涉及一种全尾砂充填材料及其制备方法，该全尾砂充填材料由如下重量份数的原料制成：全尾砂110～790份、水泥0.5～1份、辅助胶凝材料8～12份、强度激发剂0.2～0.3份、微膨胀添加剂0.22～0.35份和水52～546份。本发明提供的全尾砂充填材料具有较高的早期强度和后期强度，材料硬化前后体积微收缩，价格较低，完全满足施工要求，全尾砂充填材料可以有效提高尾矿类固体废弃物的大量利用，减少其对环境污染，是一种保证开采安全、低成本，提高废物的利用率，环境友好型矿山充填材料。
