新密煤田裴沟矿二1煤中环境敏感元素地球化学特征
Geochemistry of environment sensitive elements in the No.2-1 coal from Peigou mine, Xinmi coalfield
摘要
Abstract
Geochemistry of vanadium, chromium, arsenic, selenium and lead in seam2-1 in Peigou mine was inves-tigated using X ray fluorescence spectrometer (ARL Quant 'X), X ray diffraction (XRD) and inductively cou-ple-plasma mass spectrometry(ICP-MS). Concentration, distribution and occurrence and their relationship with tectonic movement were studied based on environment-sensitive elements content determination, minerals and minor elements composition. The results show that the average concentration of arsenic, vanadium, and chromium is obviously higher than their average concentration in other Chinese coal and American coal, the concentration of selenium and lead is generally normal; their occurrence is mainly related to the inorganic minerals except arsenic. Most of vanadium and chromium are mainly concentrated in kaolinite and illite, part of them may be associated with sulfide or sulfate. Selenium is mainly concentrated in kaolinite, and may be associated with rutile. Lead is mainly concentrated in kaolinite. The paper also discussed the effect of tectonic deformation of coal on environ-ment-sensitive element concentration and their distribution. The content of elements in different layers varied greatly, that means there is no obviously migration or homogenization in tectonic deformation of coal.关键词
