| 摘 要： | 对煤矿区的水体、土壤、煤矸石分别取样，分析了样品中各类元素含量，并基于生态危害指数评价方法对各区域的污染程度进行了综合评价。结果发现，水质与国家标准Ⅰ类水质相比较存在很大差距，Cu、Pb、Cr、Cd元素分别超标了37倍、65倍、15倍和300倍，P元素超标了17倍；与该地区土壤元素背景值进行比较，Cd、Cr、Cu、Pb、Zn、V、As、Hg、Ni、Co元素均有超标，超标在1.2～2.6倍。对26个土壤样品利用生态危害指数方法进行综合评价，发现严重污染、重度污染、中度污染和轻度污染所占比例分别为0、11.54%、61.54%和26.92%,煤矸石中关键元素的含量与土壤基本类似。基于综合评价结果，对于不同污染程度的区域，可以采用分区治理的措施提升煤矿区地质环境治理效果。

| Abstract: | The water，soil and coal gangue in the coal mine area were sampled separately，and the contents of various elements in the samples were analyzed，and the pollution degree of each area was comprehensively evaluated based on the ecological hazard index evaluation method.The results showed that there was a big gap between the water quality and the Class Ⅰ water quality of the national standard.The elements of Cu，Pb，Cr and Cd exceeded the standard by 37 times，65 times，15 times and 300 times respectively，and the element of P exceeded the standard by 17 times.Compared with the background value of soil elements in this area，Cd，Cr，Cu，Pb，Zn，V，As，Hg，Ni，Co elements all exceeded the standard by 1.2~2.6 times.The ecological hazard index method was used to comprehensively evaluate 26 soil samples.It was found that the proportions of serious pollution，heavy pollution，moderate pollution and light pollution were 0，11.54%，61.54% and 26.92% respectively.The content of key elements in coal gangue was basically similar to that of soil.Based on the comprehensive evaluation results，for the regions with different pollution levels，the measures of regional governance can be adopted to improve the effect of geological environment governance in coal mining areas. |
