开滦矿区煤中微量有害元素的含量与赋存状态
|
摘要
简述煤中微量有害元素的危害,采集河北开滦矿区的煤层煤样作为样品对其进行微量元素测试并分析煤中有害元素的赋存状态,以利于煤炭的合理开发利用。通过研究发现,开滦矿区煤中砷的含量为7mg/g,主要以硫化物的形式赋存;镉的含量为0.5mg/g,赋存状态为硫化物;铬的含量为30mg/g,主要赋存形态为黏土矿;钴的含量为8mg/g,主要赋存于硫化物,硅铝化合物次之;铅的含量为22mg/g,主要以硅铝化合物结合态存在;汞的含量为0.134mg/g,主要赋存形式为硫化物,在低硫煤中主要以有机质结合态存在;氟的含量为140mg/g,主要以无机质的形式存在。
The harm of harmful trace elements in coal was introduced briefly in this paper,the coal seam coal of Kailuan mining area was taken as the sample to proceed the trace elements test and the occurrence status of harmful trace elements in coal were analyzed,which are beneficial to the rational development and utilization of coal.Through the research it is found that the content of arsenic As is 7 mg/g,which is mainly in the form of sulfide;the content of cadmium Cd is 0.5 mg/g,the state of occurrence is sulfide;the content of chromium Cr is 30 mg/g,the main form of occurrence is clay ore;the content of cobalt Co is 8 mg/g,which mainly occurs in sulfides,followed by silicoalumino compounds;the content of lead Pb is 22 mg/g,it is mainly in the state of silicon-aluminum compound binding;the content of mercury Hg is 0.134 mg/g,which is mainly in the form of sulfide,and in the low-sulfur coal,it is mainly in the organic-bound state;the content of fluorine F is 140 mg/g,it mainly exists in the form of inorganic matter.
