摘要: 为了降低胶结充填成本,提高胶结剂对矿山充填特点的适应性,需要研究低成本、高性能的矿山专用充填胶凝材料。介绍了碱激发胶凝材料、高水材料、胶固粉和CH半水磷石膏胶凝材料。举例分析4种新型胶凝材料的特点可知,碱激发胶凝材料极大地降低了胶结剂成本,提高了固废利用率,高水材料和胶固粉明显提高了胶结剂的充填适应性,而CH半水磷石膏胶凝材料则兼顾了前后两者优点,是一种前景广阔的新型充填胶结剂。综合对比不同充填胶凝材料发展现状得出,更加重视充填体早期强度、探索更多固废资源化的可能、充分考虑矿山充填特点和胶凝材料与充填技术协同发展将是矿山胶凝材料今后发展的主要趋势。

Abstract: In order to reduce the cost of cemented filling and improve the adaptability of binders to filling characteristics,it is necessary to study low cost and high performance special cementing materials for mines.The alkali-activated cementing materials,high-water material,glue powder and CH hemi-hydrate phosphogypsum cementing material were reviewed.By analyzing the characteristics of four kinds of new cementing material,it can be seen that the alkali-activated cementing materials can greatly reduce the cost of the binders and improve the use rate of solid waste,the high-water material and glue powder can obviously improve the filling adaptability of binders and the CH semi-phosphogypsum cementing material taking their advantages into account is a promising new filling binder.Based on a comprehensive comparison on the development status of different filling binders,it is concluded that paying more attention to early strength of filling body,exploring the possibility of using more solid waste resources,fully considering the characteristics of mine filling and collaboratively developing binders and filling technology are the main development trends of filling cementing materials.
