The Characteristics of Heavy Metals of the Groundwater in the Gangue-Filled Reclamation Area

摘要

In order to study the characteristics of heavy metals of the groundwater in the gangue-filled reclamation area, the heavy metals were investigated at Ju-Ji Coal mine with high groundwater level. The samples of the groundwater were gathered in the gangue-filled reclamation area at different time, studying the characteristics of heavy metals of the groundwater. The results were as follows: the heavy metal content of the Cd, Hg, As and Pb increased with the increase of reclamation time. The heavy metal content of groundwater associated with the reclamation time in linear time.
