Three types surface soil from Datong coal mine subsidence in Huainan City of Anhui Province were collected for remediation evaluation. Sample A was from the control area with a mixture plantation, sample B was taken from an area with chemical waste filling, and sample C was taken from an area with coal gangue fillin. The physical and chemical properties, and the occurrence characteristics of Cr, Cd, Cu, Pb, and Hg of the samples were analyzed, and the environmental effects of the soil restoration were assessed. The results showed as follows:First, in the three samples, available P content in area A >area B >area C, but available N in area C >area A >area B, and content of heavy metals and exchangeable Na⁺ of area B was higher than in other areas, and in particular, the ESP(exchange sodium percentage) content was up to 22%; Second, high alkalinity of the filling soil was widespread, showing a serious lack of available N and P. The soil fertility in area A >area C >area B. Third, the levels of heavy metal pollution found in the soil showed that area A reached slight levels, area B reached moderate to high levels, and area C reached different types of heavy metal pollution. The total content of Cr, Cd, Cu and Pb in the soil was, to different degrees, greater than that found in typical Huainan City background values; Fourth, the effect of the soil restoration in subsidence sample C was superior to subsidence sample B, and the environmental problems of the soil in area B was severe, it should be improved promptly.
