Abstract: In order to discuss the element content and quality of groundwater and soil in coalstrata, chemical composition of groundwater and soil were analyzed and evaluated. The results showed that: water chemistry type of groundwater were most SO42--Ca?Mg and HCO3--Ca, in trace elements, contents of Mn was highest and its average was 4.92 mg/L; next was Zn and its average was 0.47 mg/L; the content of Cu was least and its average was 0.03 mg/L; pH of groundwater was 5.00 and belonged to acid water; average of TDS, HB, COD were 1011.44 mg/L, 659.65 mg/L, 8.33 mg/L. In trace elements of soil, the content of Cr was highest and its average was 148.00 mg/kg, next was Zn and its average was 107.76 mg/kg, the content of Cd was the least and its average was 0.43 mg/kg. Quality evaluation was showed: SO42-, Mn, Cr, Ni, pH, HB, TDS, COD were exceeded standard, comprehensive quality level was level of Ⅴ. Contents of Cu, Cd, Ni were all exceed standard, comprehensive index was 1.35 and comprehensive quality level were medium.
