Spontaneous combustion coal gangue-based low-strength grouting material and preparation method thereof
The invention relates to the field of mine solid waste resource utilization, in particular to a spontaneous combustion coal gangue based low-strength grouting material and a preparation method thereof.The spontaneous combustion coal gangue based low-strength grouting material is prepared from spontaneous combustion coal gangue, carbide slag, fly ash, desulfurized gypsum and composite Portland cement according to the mass ratio of 5: 2: 3 or 5: 3: 2; the addition amount of the carbide slag is 9-10% of the total mass of the solid. The grouting material can partially replace cement, is low in cost and stable in performance and meets the grouting requirement, the comprehensive utilization rate of solid waste such as spontaneous combustion coal gangue, coal ash, desulfurized gypsum and carbide slag can be increased, and the filling and grouting cost of related enterprises such as mineral exploitation can be greatly reduced.
本发明涉及矿山固废资源化利用领域，具体涉及一种自燃煤矸石基低强度注浆材料及其制备方法，包括以下原料制成：自燃煤矸石、电石渣、粉煤灰、脱硫石膏和复合硅酸盐水泥，所述自燃煤矸石、粉煤灰和复合硅酸盐水泥的质量配比为5:2:3或5:3:2，所述电石渣的添加量为固体总质量的9‑10％。本发明能够部分替代水泥的成本低廉、性能稳定、符合灌注要求的注浆材料，不仅可以提高自燃煤矸石、粉煤灰、脱硫石膏和电石渣等固废的综合利用率，且可以大幅降低矿产开采等相关企业充填注浆成本。
