通过对晋东南和豫中地区几个煤矿矸石堆及其周围的土壤和水体、井下矸石取样分析,发现这些矿的煤矸石中全氮的背景值为0.4%-0.8%.在中高煤变质程度地区,含铵伊利石夹矸中全氮高达1.0%-1.6%,铵伊利石的存在对于矸石堆中全氮含量的提高具有贡献.在矸石山周围积水中,具有较高的氮含量,说明雨水比较容易从矸石堆中将氮淋滤出来.煤矸石堆周围土壤中的氮含量并不高,说明煤矸石淋滤物并没有发生明显的横向迁移,可能主要表现为垂向渗透,有可能对地下水造成潜在的氮污染.

Based on the analysis of samples from coal gangue,soil and leached water around gangue pile,it was found that the background content of total nitrogen in coal gangue is about 0.4%-0.8%.but the total nitrogen content in ammonium illite-bearing gangue is up to 1.0%-1.6%.So that,the existence of ammonium illite in the area of high metamorphic coal will contribute to the elevated nitrogen content.The leached water around coal gangue has high content of nitrogen,which shows that the nitrogen in the gangue is easy to be leached out by rain.The soil around the coal gangue has lower nitrogen content,which shows that leached water does not flow laterally,but possibly infiltres vertically,which may cause potential nitrogen pollution.
