Description
Summary:The impact on these water bodies of the surrounding coal production activities and the power plant through research the content and characteristics of harmful trace elements in coal contained in these water bodies. F, Hg, Se and As these four trace ele- ments increased 0.92%, 0.78%, 0.70% and 0.81% respectively in Datong mining subsi- dence pool from November 2004 to November 2006; the four elements increased 1.58%, 1.23%, 1.08% and 0.92% respectively in Xie＇er mining subsidence pool; the four elements increased 1.16%, 1.06%, 1.02% and 1.01% respectively in Pansan mining subsidence pool. The conclusions show that the absolute values of F, Hg, Se and As in mining subsidence pool are relate with their background value, while the increase in their concen- tration and their environment of mine and electricity plant surrounded are closely linked.
