Backfill material prepared from gold tailing sand as well as preparation method and application of backfill material
The invention provides a backfill material prepared from gold mine tailing sand as well as a preparation method and application thereof, and belongs to the field of gold mine tailing sand recycling. The backfill material prepared from the gold mine tailing sand comprises the following components: a special curing agent for mine backfill and the gold mine tailing sand, the special curing agent for mine backfill comprises the following components: cement clinker, slag, sodium chloride, sodium sulfate, aluminum sulfate and polyacrylamide. The specific surface area of the special curing agent for mine backfill is greater than or equal to 450m < 2 >/ According to the backfill material prepared from the gold mine tailing sand, the gold mine tailing sand can be effectively recycled, and the problems that in existing gold mine tailing sand recycling, the utilization ways of fine gold mine tailing sand are few, consumption is low, and effective recycling cannot be achieved are effectively solved, and the problems of environmental pollution, serious dust raising and management difficulty caused by the gold mine tailing sand are effectively solved.
本发明提供一种由金矿尾矿砂制成的回填材料、制备方法及应用，属于金矿尾矿砂回用领域。所述由金矿尾矿砂制成的回填材料包括有以下成分：矿山回填专用固化剂、金矿尾矿砂；所述矿山回填专用固化剂，包括有以下成分：水泥熟料、矿渣、氯化钠、硫酸钠，硫酸铝，聚丙烯酰胺；所述矿山回填专用固化剂的比表面积≥450m2/Kg。本发明的由金矿尾矿砂制成的回填材料，能够对金矿尾矿砂进行有效回用，有效解决现有金矿尾矿砂回用中存在的细金矿尾矿砂利用途径少，消耗量低，无法实现有效回用的问题，以及金矿尾矿砂导致的环境污染、扬尘严重、管理困难问题。
