| 摘 要： | 分析了粉煤灰胶凝活性及其主要影响因素，介绍了粉煤灰在国内外矿山胶结充填中应用的研究概况。粉煤灰用于充填，不仅可以大幅度降低充填成本，而且还可以显著提高充填体后期强度，改善充填体和料浆性能，避免粉煤灰对环境的污染；然而粉煤灰用于充填，一般会造成充填体早期强度低，延长采场回采周期，所以，在充填环境条件下，有效激发粉煤灰提高...

| Abstract: | In this paper,the cementitious activity of fly ash and the main factors influencing its cementitious activity are analyzed.Both the foreign and domestic studies on the application of fly ash to cemented backfilling in mine are introduced.The studies show that application of fly ash to mine backfilling not only can cut down the cost of backfilling,but also improve the later strength and properties of backfilling body,avoid the pollution of fly ash to environment;however,fly ash used in backfilling maybe make... |
