新型矿山充填胶凝材料的研究与应用综述

Review on Development and Application of New Type Backfilling Cementing Materials in Mining Industry

伴随着采空区胶结充填技术的发展,充填胶凝材料的研究与应用技术取得了长足的发展。介绍了高水速凝充填胶凝材料、粉煤灰充填胶凝材料、矿渣基充填胶凝材料等新型充填胶凝材料在矿山行业的研究及应用概况,分析了不同充填胶凝材料的特点和局限性,提出了开发具有潜在胶凝活性的工业固体废料、降低充填胶凝材料成本和改善胶凝材料性能将是充填材料今后发展的方向。

With the development of cementing filling technology in mined-out area,backfill material research and appli-cation technology has made great development. The features and performances of different cementing materials such as high-wa-ter rapid-setting cementing material, fly ash backfill cementing materials and blast furnace slag backfill cementing materials were reviewed. It is suggested that the solid wastes with potential cementing activity,backfill material with low costs,methods can improve gelled material properties will be the future development direction.
