摘要
铝矿床底板土是平果铝矿复垦的主要覆土材料 ,但由于其理化性状差 ,用作复垦地的耕作层需要进行土质改良 ,粉煤灰是这类粘质底板土最经济可行的改性材料。通过一系列的试验研究 ,确定了粉煤灰与底板土的最佳配比 。
The floor earth of bauxite deposit is main reclamation material in Pingguo Bauxite Mine. Because of its poor physical chemical properties, when used as cultivable layers in reclamation field, the floor earth needs some modification. Fly ash is the most economic and available material for modification of the glutinous floor earth. By a series of experiments, the optimal proportion of fly ash to floor earth is determined ultimately, and then the real effect of soil amelioration investigated.
