平果铝土矿采空区复垦试验研究

Experimental Research of Reclamation in the Mined Area of Pingguo Bauxite Mine

以尾矿滤饼为主要材料 ,添加适量粉煤灰 ,通过大豆培肥 ,用于平果铝土矿采空区复垦。试验结果表明 ,尾矿滤饼添加适量粉煤灰的耕作层经过一年的培肥熟化后 ,即可种植农作物 ,其产量超过了当地同种农作物的产量 。

In the reclamation test in the mined area of Pingguo Bauxite Mine,the filter cake of tailings which was used as the main material was mixed with appropriate amount of coal ash powder and soybean was planted for land fertilization. Test results have shown that the cultivable layer made of the filter cake of tailings mixed with appropriate coal ash powder,after one year's fertilization and cultivation, can be used for planting crops and their production can pass that of the same local crops, which proves a good cultivation result.
