The Element Geochemistry of Coal Mine Drainage Pollution in Coal Mine from Northern Jiangsu Province

摘要：

　　The content of environmentally-sensitive elements released from coal gangue and the element geochemistry of coal mine drainage (CMD) in Kongzhuang coal mine were investigated on the basis of a soaking test.Results show that the content of volatile elements Hg and As released from the newly-explored gangue is higher than that from the old-gangue, and the Hg and Pb contents from the roof are higher than that from the floor.Hg, Se, P, Cd, Pb and SO42 contents in CMD exceed the environment quality standards.Generally, the microorganism may play an important role in the pollution of CMD.
