| 摘 要： | 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迁移的能力，根据对煤矸石堆周转土壤中微量元素的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。

| Abstract: | Under water and some other conditions, trace and minor elements in coal or waste rocks will migrate and separate out from coal or waste rocks into the soil environment with water. They will move and concentrate in the soil environment,but their capacity of migration is controlled by conditions of soil environment. In this paper, the migration capacity of trace and minor elements is analyzed on the basis of leaching experiments.According to the contents of trace and minor elements in horizontal vertical directions around heaps of waste rocks, the effect on soil and the migration capacity of trace and minor elements are studied. This study will provide data for evaluating environmental effects in the soil environment. |
