| The Migration of Trace and Minor Elements of Coal in the Soil Environment |
| 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. |
