Soil ph in abandoned coal mine lands ranged from 5.30 to 6.76 it in the control site was Contents of organic matter and total N in abandoned coal mine lands were 4.46~7.19% and 0.07~0.15%, respectively. Available P contents were 6.54 for A (Samchang), 6.52 for B (Bongmyeong), 3.94 for C (Kabjung), 5.45 mg/kg for D (Danbong coal mine land) and 5.25 mg/kg for the control site, which had a positive correlation with soil ph. Contents of exchangeable Ca, Mg, K and Na in abandoned coal mile lands averaged 196.1, 88.7, 88.2 and 10.2 cmol + /kg, with a range of 132.1~242.1, 24.2~ ~120.8 and 8~12.2 cmol + /kg, respectively. Those of the control site were 192.8, 95.8, 104 and 21.2 cmol + /kg, respectively. Heavy metals such as Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn of forest soil in abandoned coal mine lands have a larger content than those of the control site. Al, Mn and Pb content was especially high in abandoned coal mine lands. The Al content of forest soil in abandoned coal mine lands ranged from 397 to 917 ppm, which was considered to be high enough to inhibit tree growth. Therefore, it is suggested that soils of abandoned coal mine lands contaminated by mining activities need to be properly treated for remediation of environmental problems.
