Mining gob-side entry retaining high-water filling material and preparation method thereof
The invention relates to a mining gob-side entry retaining high-water filling material and a preparation method thereof, belongs to the technical field of filling materials, and aims to solve the problems of high cost and long setting time of an existing filling material. The mining gob-side entry retaining high-water filling material is prepared from a component A and a component B. The componentA is prepared from, by mass, 400-600 parts of sulphoaluminate cement, 50-150 parts of Portland cement and 1-2 parts of a retarder. The component B is prepared from, by mass, 300-400 parts of red mud,100-200 parts of coal gangue, 30-50 parts of an excitant and 1-2 parts of sizing glue. The filling material has the advantages of low cost, short setting time, high compressive strength and the like,harmless comprehensive utilization of industrial solid wastes is realized, and the material cost is effectively reduced.
本发明涉及一种矿用沿空留巷高水充填材料及其制备方法，属于充填材料技术领域，用以解决现有充填材料成本高、凝结时间长的问题。本发明的矿用沿空留巷高水充填材料，包括A组分和B组分，原料按质量分数构成为：A组分包括：硫铝酸盐水泥400‑600份，硅酸盐水泥50‑150份，缓凝剂1‑2份；B组分包括：赤泥300‑400份，煤矸石100‑200份，激发剂30‑50份，定优胶1‑2份。本发明具有成本低、凝结时间短、抗压强度高等优点，且实现了工业固废的无害化综合利用，有效降低了材料成本。
