Multi-solid-waste cemented filling material for superfine full tailings and preparation method of multi-solid-waste cemented filling material
The invention discloses a multi-solid-waste cemented filling material for superfine full tailings and a preparation method, and belongs to the technical field of underground filling of metal mines. The cement comprises the following components in percentage by mass: 40-65% of slag powder, 15-40.5% of steel slag powder, 3-9% of desulfurized gypsum, 3-7.5% of carbide slag, 0-10% of fly ash, 0-25% of dry desulfurized fly ash and 1-2% of a composite additive. The preparation method of the multi-solid-waste cemented filling material is simple, low-carbon and environment-friendly, the steel slag can be used on a large scale without adding mud clinker, a water reducing agent and an early strength agent are not used, the problem that the filling strength of metal mine superfine tailings is low is solved, and resourceful treatment of various industrial solid wastes is also achieved.
一种用于超细全尾砂的多固废胶结充填材料及制备方法，属于金属矿山井下充填技术领域。以质量百分比计，其组成为：矿渣粉：40～65%，钢渣粉：15～40.5%，脱硫石膏：3～9%，电石渣：3～7.5%，粉煤灰：0～10%，干法脱硫灰：0～25%，复合添加剂1～2%。该多固废胶结充填材料制备方法简单，低碳环保，可规模化化使用钢渣而无需添加泥熟料，没有减水剂和早强剂，解决了金属矿山超细尾矿充填强度低难题，也实现了多种工业固废资源化处理。
