Abstract :
Based on leaching experiment, the leaching of heavy metal in mine waste was brought out. The research showed that Zn, Cr, Pb and Cu concentrations are most in the leachate of weathered coal waste, and the concentration became stable rapidly; only Zn concentrations are found in fresh mine waste leachate in the beginning time. The soil around mine waste also was contaminated by heavy metal, such as Zn, Cr and Pb .The process that heavy metal is leached out is a long time, and heavy metal could be migrated and accumulated. The contents of heavy metals of soil samples decreased with distance. The content of heavy metals decreased with the depth.
