煤或煤矸石中的微量元素在水等条件作用下发生变化 ,并从其中析出随水体进入土壤环境中 ,在土壤环境中发生迁移和富集 ,其迁移的能力受土壤环境条件的制约。本文通过对煤的淋溶实验 ,分析了煤中微量元素在土壤环境中迁移的能力 ,根据对煤矸石堆周围土壤中微量元素在平面上和垂向上的含量变化 ,研究了微量元素在土壤环境中的富集能力及煤中微量元素对土壤环境的影响 ,为正确评价煤中微量元素在土壤中的环境效应提供依据。
Trace elements in coal or coal gangue change under the influence of water and other conditions, and precipitate from them into the soil environment with the water into the soil environment in the migration and enrichment, its ability to migrate by the soil environmental conditions. In this paper, leaching experiments on coal were carried out to analyze the ability of trace elements in coal to migrate in the soil environment. According to the content of trace elements in the soil around the gangue heap in the vertical and horizontal direction, the effects of trace elements on soil environment Enrichment ability of coal and the influence of trace elements in coal on soil environment, which provided the basis for correctly evaluating the environmental effects of trace elements in coal.
