Abstract: Heavy metal concentrations were measured in soil, groundwater and plants around the coal gangue pile of Yanma Mine, Jiaozuo City. According to the local topography, property of soil and hydrodynamic condition of groundwater, research on therelation between the coal gangue pile and environmental pollution was conducted, which is scientific foundation for heavy metal pollution control of the mine area. The sampling sites of soil, groundwater and plants were arranged around thecoal gangue pile of Yanma Mine, and the distributions of pH and heavy metals (such as Pb, Mn, Zn, Cu, Cr and Cd) were measured. The results show as follows: the piling-up of coal gangue is an important source of environmental pollution, and most heavy metals from coal gangue are absorbed by soil. All of the measured heavy metals in soil are above detection limits. Moreover, some concentrations of Zn and Cd have exceeded the secondary standard of Standard of Soil Environmental Quality (GB15618-1995). Heavy metals can migrate from soil to groundwater and plants. There is negative correlation between the concentrations of Mn andthe distances between the coal gangue pile and the sample sites. The concentrations of Pb in leaves are larger than that in stems and seeds, and there is correlation between the concentrations of heavy metal in leaves and stems and the coal gangue pile. Mine drainage water and boiler dusts are also important sources of heavy metal pollution around the coal gangue pile.
