Filling material for filling mine, preparation method of filling material and method for filling mine
The invention provides a filling material for filling a mine, a preparation method of the filling material and a method for filling the mine. The filling material for filling the mine, provided by the invention, is prepared from the following raw materials in percentage by mass: 30-40% of an environmental remediation material; 50%-60% of a polyurethane foam raw material; 4%-8% of an inorganic flame retardant; and 0.6%-2% of a foam stabilizer. The specific environment repairing material, the polyurethane foam raw material, the inorganic flame retardant and the foam stabilizer are combined to form the filling material, so that the compressive strength of the material can be improved, and the filling material has a good flame-retardant effect and has the advantages of high construction speed, low cost and the like; in addition, a large amount of fly ash is used in the raw materials, compared with direct use of concrete, the use rate of the formed building material can be obviously reduced, the product belongs to an efficient, economical, low-carbon and environment-friendly product, and meanwhile cyclic utilization of waste resources is achieved.
本发明提供了一种填充矿井的填充材料及其制备方法，以及填充矿井的方法。本发明提供的填充矿井的填充材料，由包括以下质量比组分的原料形成：环境修复材料30％～40％；聚氨酯泡沫原料50％～60％；无机阻燃剂4％～8％；稳泡剂0.6％～2％。本发明将特定的环境修复材料、聚氨酯泡沫原料、无机阻燃剂和稳泡剂结合形成填充材料，能够提高材料的抗压强度、还具有良好的阻燃效果，且具有施工快速、成本低廉等优点；另外，原料中大量使用粉煤灰，与直接采用混凝土相比，能够明显降低成型建材的使用率，属于高效节约、低碳环保型产品，同时实现了废弃资源的循环利用。
