摘　　要：以焦作矿务局演马矿煤矸石山为对象,采集该处煤矸石及其周围的表层土壤,进行了重金属和pH值检测,并采用Euc lid贴近度评价法,综合分析研究土壤的重金属(Pb、Zn、Cu、Cr、Cd)的污染,结果表明在距离矸石山一定范围内的土壤存在重金属超标现象,并且,土壤中重金属污染与距煤矸石山的距离成负相关。Taking coal gangue pile in Yanma Coal Mine of Jiaozuo Mining Bureau as the investigated subject, the coal gangue pile and surrounding surface soil were sampled. The heavy metal amounts and pH value of samples were measured. The heavy metal （Pb, Zn, Cu, Cr, Cd） pollution situation in the surrounding soil was studied in Euclid approach degree assessment method. The result showed that the heavy metal amounts of the soil in certain distance to the coal gangue pile exceeding the standard, and the heavy metal amounts in the soil are negative correlation with the distance to the coal gangue pile.
