In order to research the migration of contaminations from coal waste rock, based on local landform, flow direction of groundwater and wind direction around the coal waste rock dump of Yanma mine, samples of soil, groundwater and plant were collected and measured. The results showed that the contents of heavy metal, Bap and SO₄^2- were high in coal waste rock, Zn and Cd had exceeded the grade III of Environmental quality standard for soils (GB15618-1995) in some samples. These components were also detected in soil and groundwater. The content of heavy metal and Bap was leaf>;stem>;seed for maize, and Bap was unattainment (7.395ng/g) in leaf. Background value of Mn was higher (422.09~599.03ppm). Mn was leached out from soil in leaching experiment, which made the Mn content of "coal waste rock + soil" leachate was higher. The above study showed that the migration of contaminants from coal waste rock to the environment was a long-term process.
