淮南顾桥与新庄孜采煤沉陷区土壤镉的差异性研究
|
摘要
对淮南顾桥和新庄孜采煤沉陷区土壤进行采样测试,研究沉陷区土壤中镉的分布及沉陷时间和矸石充填对土壤中镉分布的影响。研究结果表明,受长期的累积作用和下伏充填矸石的影响,新庄孜矿表层土壤中总镉含量是顾桥矿的9.37倍。顾桥矿区土壤镉含量从土壤表层向下呈现出先降低后增加的趋势。受淋滤作用和地形控制,新庄孜充填复垦区土壤中镉含量随深度变化呈现两种变化趋势,一是地势高处先降低后增高,二是地势低处先增加再降低。
Soils in Huainan Guqiao and Xinzhuangzi coal mining-induced subsidence area were sampled and tested to study the distribution of surface cadmium in the subsidence area and the influence of subsidence time and vermiculite filling on the cadmium distribution in the soil. The results of the study showed that the total cadmium content in the surface soil of the Xinzhuangzi mine was 9.37 times higher than that of Guqiao mine due to the long-term cumulation and underlying filling gangue. The soil cadmium content in Guqiao mining area showed a downward trend and then increased from the surface of the soil. Affected by leaching and topography, the soil cadmium in the filling and reclaiming area of Xinzhuangzi has two change trends with depth. First, in high terrain the cadmium content decreases firstly and then increases, while in low terrain the cadmium content increases firstly and then decreases.
