粉煤灰对石墨尾矿持水特性的影响
Influence of fly ash on water retention characteristics of graphite tailings
摘要
Abstract
This paper aims to address the weak water retention capacity and the poor wind erosion re-sistance of graphite tailings.The study involves measuring the water infiltration of graphite tailings by u-sing the ring knife method,investigating the variation of infiltration with time,analyzing the effects of the infiltration amount,infiltration rate,and saturated hydraulic conductivity on the water retention property of graphite tailings;and analyzing the infiltration properties of graphite tailings by adding fly ash based on the three infiltration models—Kostiakov,Philip and Horton.The results show that the water retention properties of graphite tailings are related to the infiltration amount,infiltration rate,and saturated hydrau-lic conductivity.The addition of different mass fractions of fly ash significantly improves the water reten-tion properties of graphite tailings.The infiltration rate of graphite tailings is negatively correlated with the mass fraction of fly ash,and the best water retention performance is achieved when the fly ash content is 2%-5%.The coefficients of determination(R2)for the Kostiakov,Philip and Horton models are 0.841,0.772 and 0.885,respectively,indicating that the Horton model performs better in describing the infiltration behavior of graphite tailings with fly ash added.关键词
