煤矿酸性矿井水研究进展

PROGRESS IN THE RESEARCH OF ACID MINE DRAINAGE

中高硫煤在开采及开采后的相当长时间内,煤层、围岩中的硫化物矿物与氧气和水接触,极易产生大量的酸性矿井水,对矿业生产和生态环境造成严重危害。本文在全面综合国内外相关研究文献的基础上,分析了酸性矿井水的水质特征、分布情况、形成机制、衰减规律及工程治理等方面研究的进展,并较为详细地论述和分析了今后的研究重点内容和发展方向,即在深入研究酸性矿井水水文地球化学的基础上,加强酸性矿井水环境学和治理新工艺方面的研究。

Acid mine drainage (AMD) causes various environmental problems.The pollution of streams and groundwater is most important among these problems. which limits usable water resources and destroys aquatic ecosystems. In this paper, the development of the study on AMD is systemadcally reviewed. Finally authors point out that comprehensive study of environmental impacts and development of effective treatment technologies about AMD are most important in the future.
