Filling material for mine and preparation method thereof
The invention relates to the technical field of filling materials, in particular to a mine filling material and a preparation method thereof. The filling material is prepared from the following raw materials in parts by weight: 6 to 20 parts of cement, 3 to 6 parts of silica powder, 2 to 5 parts of fly ash, 58 to 75 parts of mixed material, 1.2 to 1.8 parts of polypropylene fiber, 2.5 to 3.0 parts of bentonite, 3.0 to 3.5 parts of citrate gypsum, 1.0 to 1.5 parts of anhydrous sodium sulfate, 0.8 to 1.5 parts of water reducing agent and 5 to 8 parts of water; the self-made water reducing agent is used as a raw material for preparing the filling material for the mine, so that the flowing property and the pumping property of the filling material can be effectively improved, and the working performance of the filling material is improved; moreover, silica powder, fly ash and the like are used as raw materials, so that the flowability and workability of the filling slurry are further improved, and the quality of the prepared filling material for the mine is effectively ensured.
本发明涉及填充材料技术领域，具体为一种矿山用填充材料及其制备方法；所述填充材料由如下重量份原料组成：6～20份水泥、3～6份硅微粉、2～5份粉煤灰、58～75份混合物料、1.2～1.8份聚丙烯纤维、2.5～3.0份膨润土、3.0～3.5份柠檬酸石膏、1.0～1.5份无水硫酸钠、0.8～1.5份减水剂及5～8份水；以本发明自制的减水剂作为制备矿山用填充材料的原料能有效地提高填充材料的流动性能及泵送性能，提高了其工作性能；而且，本发明中还以硅微粉及粉煤灰等为原料进一步地改善了填充浆料的流动性及和易性，有效地保证了所制备的矿山用填充材料的品质。
