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.
