| 摘 要： | 以抚顺矿区汪良排土场、东排土场和西排土场为研究对象,选择荒草地类型区进行采样,研究了不同粒级煤矸石风化物矿质元素含量的变化,并对不同粒级煤矸石风化物成壤指标进行了测定。结果表明,随煤矸石风化物堆积年限的增加,SiO2,Al2O3和Fe2O3的含量在不同粒级间变化不大,K2O,Na2O,CaO,MgO的含量变化明显;由各个成壤指标来看,煤矸石堆积物的风化程度随堆积年限的增长和粒级的减小而增强。

| Abstract: | In the coal waste piles of Wangliang,East,and West,the uncroping land was chosen as soil sampling.The special variation of mineral elements in coal waste weathering in different partical fractions was researched and the coal waste soil formation indexes were determined.The results indicate that the contents of SiO2 and Al2O3 have not great changes with weathering time or piled up time,but the contents of Fe2O3,K2O,Na2O,CaO, and MgO have obvious change.From the weathering indexes,weathering intensity in surface layer is better than in the bottom layer;the longer the piled up time,and the smaller the partical diameter,the higher weathering intensity. |
