庞庄煤矿煤矸石淋溶液对周边水体影响分析

为研究庞庄煤矿张小楼煤矸石堆场淋溶液对其场地和周边地表水、地下水水质影响情况，围绕煤矸石堆场及周边采集13组水样做分析比对。结果表明，煤矸石堆场淋溶液对周边地表水体形成普遍污染，且污染物浓度随着污染距离增加逐步降低，一般化学污染指标主要包括溶解性总固体、硫酸盐、铁、锰、氨氮等，毒理学污染指标包括亚硝酸盐、氟化物、砷，超标倍率约为0.02~5.36。受距离及成井深度等因素影响，地下水体未遭受淋溶液明显的污染和影响。

Analysis of Impact of Coal Gangue Leaching on Surrounding Water in Pangzhuang Coal Mine

13 groups of water samples were collected from Zhangxiaolou coal gangue dump and surrounding areas of Pangzhuang Coal Mine for analysis and comparison, the impact of coal gangue leaching on the quality of surface water and groundwater in this area was studied. The results showed that the leaching solution from the coal gangue dump caused widespread pollution on surrounding surface water, and the pollutant concentration gradually decreases with the increase of pollution distance. The general chemical pollution indicators mainly included dissolved total solids, sulfate, iron, manganese, ammonia nitrogen etc.. Toxicological pollution indicators included nitrite, fluoride and arsenic. The over-standard rate was about 0.02 to 5.36. The groundwater was not significantly affected by the leaching solution due to the influence of distance and well depth.
