监测了不同粒径的煤矸石、粉煤灰及其不同配比的基质在水的长时间漫泡下,其pH的变化规律。并寻找出了适宜于作物生长的粉煤灰与煤矸石的最佳pH配比比例为4:1-8:1。为进一步就地取材,以废治废提供新的思路,可以减少煤矿区生态恢复的费用... 监测了不同粒径的煤矸石、粉煤灰及其不同配比的基质在水的长时间漫泡下,其pH的变化规律。并寻找出了适宜于作物生长的粉煤灰与煤矸石的最佳pH配比比例为4:1-8:1。为进一步就地取材,以废治废提供新的思路,可以减少煤矿区生态恢复的费用,具有很好的实际应用潜力。 展开更多

Mine rocky desertification is another type of rocky desertification which coexists with Karst rocky desertification, suggested firstly by professor SONG Jian-bo, Guizhou University. Mine rocky desertification is a process and result that the earth's surface is similar to desert landscapes after rock is exposed gradually, owing to mine wastes discharged at will which consist of waste residue, waste liquid and waste gas. On the basis of introducing Karst rocky desertification simply, we clarify the concept of Mine rocky desertification systemically, analyze its danger and compare the differences between Mine rocky desertification and Karst rocky desertification. Finally, we make preliminary discussion on the study significance of comprehensive treatment of Mine rocky desertification 展开更多
