3) wasteland
[英]['weɪstlænd] [美]['west'lænd]
煤矿废弃地
1.
Using field investigation and quadrat method,a study was conducted on the vegetation and flora of the coalmine wasteland in Mingshan Mountain,Meizhou,Guangdong.
通过野外实地考察,采用样方法,调查了广东梅州明山煤矿废弃地的植被和植物区系。
5) rejected fly ash
废弃粉煤灰
1.
By means of radial Dynamic Leaching Test(r-DLT),it was studied that the behaviors of heavy metal hydroxides in the solidified and stabilized(S/S) samples contained cement and rejected fly ash.
采用径向动态浸出实验(r-DLT)研究了含废弃粉煤灰-水泥固化/稳定样品内部重金属铅、铜、锌的氢氧化物的迁移行为,发现重金属在酸溶液作用下虽然会从样品内部向外迁移,但不同重金属的迁移规律各不相同。
2.
Using tests of compressive strength, hydration product and porosity, the influen ce of steam curing on the pozzolanic reaction of rejected fly ash were studied.
通过研究蒸汽养护条件下含废弃粉煤灰的样品在抗压强度、水化产物以及孔隙率等方面的变化,探讨了蒸汽养护对废弃粉煤灰火山灰活性的影响。
6) mining offal
采煤废弃物
1.
In-door planting experiment was carried out to study the influence of the mining offal,using coal refuse and fly ash as the planting medium,on the crop of red soybean.
结果表明:(1)粉煤灰物理性质不适于作物生长,对作物长势影响最大,在粉煤灰排放场不覆土直接种植作物不可取;(2)煤矸石和粉煤灰会对作物产生重金属污染,尤其是细颗粒煤矸石的污染最大;(3)充填采煤废弃物复垦应该保证足够的覆土厚度。
