Abstract

Abstract

Characteristics of heavy metal in coal mine reclamation area is of great significance to the selection of land reclamation methods. Take the soil of Shanxi coal mine reclamation area as the research object. The characteristics of heavy metals in deep and shallow mining were studied. The results showed that the heavy metal content in deep reclamation area was significantly higher than in unreclaimed area, The Zn content is 6.23 times that of the unreclaimed areas, and more than 9 times the national standard value; Soil in the deep reclamation areas has been contaminated by Zn and Cr; Heavy metal content in shallow reclamation area is higher than in unreclaimed area, But lower than the national standard value; Pb in the coal mine reclamation area has a high pollution impact on the surrounding soil; Although Zn is large in its soil, However, with little impact on the environment, Heavy metals Ni and Cr are dangerous to the surrounding soils under certain conditions; Maximum RSP of heavy metal Pb in deep and shallow reclamation areas, Maximum environmental impact, The other three heavy metals have no pollution.
