Mine paste filling material as well as preparation method and application thereof
The invention discloses a mine paste filling material, and relates to the technical field of environmental protection engineering, and the mine paste filling material specifically comprises the following raw materials by weight: superfine tailings, a filling cementing agent and water; wherein the mass ratio of the superfine tailings to the filling cementing agent is 1: (4-7); the mass of the water is 15-35% of the total mass of the superfine tailings and the filling cementing agent; the filling cementing agent comprises the following raw materials in percentage by weight: 40-85% of molten iron pre-desulfurization slag and 15-60% of desulfurized gypsum. Meanwhile, the invention further discloses a method for preparing the mine pasty fluid filling material by mixing the raw materials and application of the mine pasty fluid filling material in filling of a mine goaf. On one hand, the problem that the molten iron pre-desulfurized slag is difficult to recycle in current iron and steel enterprises is solved, and on the other hand, the long-term bottleneck problem of high preparation cost of the cemented filling material in the underground mining field is solved by utilizing the characteristics that the molten iron pre-desulfurized slag is low in price, easy to obtain and even available for disposal and subsidy.
本发明公开了一种矿井膏体充填料，涉及环保工程技术领域，具体包括以下重量分数的原料：特细尾矿、充填胶结剂和水；其中，所述特细尾矿与所述充填胶结剂的质量比为1:(4‑7)；所述水为特细尾矿和充填胶结剂总质量的15‑35％；所述充填胶结剂包括以下重量分数的原料：铁水预脱硫渣40‑85％，脱硫石膏15‑60％。同时，本发明还公开了将上述原料混合制备矿井膏体填充料的方法以及矿井膏体充填料在矿山采空区充填中的应用。本发明一方面解决了目前钢铁企业铁水预脱硫渣难以资源化利用的难题，另一方面利用铁水预脱硫渣的价廉易得甚至有处置补贴的特点，解决长期困扰地下采矿领域胶结充填料制备成本高的瓶颈问题。
