Goaf filling cementing material, filling test block and preparation method thereof
The invention discloses a goaf filling cementing material, a filling test block and a preparation method of the goaf filling cementing material. The goaf filling cementing material comprises the following components in percentage by mass: 50-70% of stone coal vanadium extraction tailings, 5-20% of stone coal vanadium extraction neutralization slag, 0-15% of smelting slag, 10-30% of cement clinker and 2-8% of an exciting agent. The filling test block further comprises a full tailing filling material and tap water, the mass percentage of the tap water is 18-30%, and the mass ratio of the goaf filling cementing material to the full tailing filling material is 1: 12-1: 4. The gelling material for filling the goaf takes the stone coal vanadium extraction tailings as a main raw material, can be applied to mine tailing filling nearby, is beneficial to large-scale and stable absorption of the vanadium tailings, avoids the problems caused by tailing accumulation, and plays a positive role in green development of mines, mining development and social environment-friendly development. The preparation method of the goaf filling cementing material is simple in process, the used main raw materials can be obtained nearby, and the production cost of the cementing material can be reduced.
本发明公开了一种采空区充填胶凝材料、充填试块及其制备方法，该采空区充填胶凝材料的质量配比为：石煤提钒尾渣50～70％，石煤提钒中和渣5～20％，冶炼渣0～15％，水泥熟料10～30％，激发剂2～8％。该充填试块还包括全尾砂充填料和自来水，所述自来水质量百分比为18～30％，所述采空区充填胶凝材料与所述全尾砂充填料的质量比为1:12～1:4。该采空区充填胶凝材料以石煤提钒尾渣为主要原料，能够就近应用于矿山尾矿充填，有助于大规模、稳定的消纳钒尾渣，避免尾渣堆积产生的问题，对矿山的绿色发展及矿业开发与社会环境友好发展有着积极的作用。该采空区充填胶凝材料制备方法工艺简单，所用的主要原料可就近取材，有助于降低胶凝材料的生产成本。
