Mining filling material as well as preparation method and application thereof
The invention relates to the technical field of mining materials, and particularly discloses a mining filling material as well as a preparation method and application thereof. The mining filling material is prepared from the following raw materials in parts by weight: 80 to 120 parts of gypsum, 8 to 12 parts of cement, 0.02 to 0.08 part of an efficient super plasticizer, 0.03 to 0.07 part of an expanding agent, 0.01 to 0.07 part of a retarder, 6 to 15 parts of fly ash, 6 to 10 parts of carbide slag and 15 to 45 parts of a compound, and the compound is formed by compounding nano silicon dioxide and Na-montmorillonite; the preparation method comprises the following steps: uniformly mixing the gypsum, the cement, the efficient super plasticizer, the expanding agent, the retarder, the fly ash, the carbide slag and the compound, and crushing to obtain the mining filling material. The mining filling material disclosed by the invention has the advantage of improving the compressive strength of the mining filling material through the synergistic effect of the raw materials.
本申请涉及矿用材料的技术领域，具体公开了一种矿用充填材料及其制备方法和应用。矿用充填材料，其包括以下重量份的原料：石膏80‑120份、水泥8‑12份、高效超塑化剂0.02‑0.08份、膨胀剂0.03‑0.07份、缓凝剂0.01‑0.07份、粉煤灰6‑15份、电石渣6‑10份、复合物15‑45份，其中复合物为采用纳米二氧化硅和钠基蒙脱土复合而成；其制备方法为：将石膏、水泥、高效超塑化剂、膨胀剂、缓凝剂、粉煤灰、电石渣、复合物混合均匀，粉碎后得到矿用充填材料。本申请的矿用充填材料，通过原料之间的协同作用，具有提高矿用充填材料的抗压强度的优点。
