Mode Of Occurrence And Geological Origin Of Arsenic In Coal From Santanghu Basin

As "Xinjiang transporting coal","Xinjiang Power Transmission" an importantbase of the eastern region of Xinjiang is the eastern spit, Balikun coalfield areasantanghu contained Hami Basin coalfield. A large number of geological survey dataindicate that the Han Quan Santanghu coalfield are three arsenic coal mining, coalarsenic levels up to190μg/g. High arsenic coal threat to human health through thesoil, arsenic in drinking water, food chain, air and other means. So figure out arsenicin coal combines with other elements and material way, arsenic-rich geological origin,the development of clean coal technology, environmental protection is important, butalso for the subsequent rational exploitation of coal resources to provide a scientificbasis.Santanghu Basin coal for arsenic enrichment, using MS, low temperature ashingafter X-ray diffraction, SEM-EDX analysis and mathematical statistics method todetermine the mode of occurrence Santanghu high arsenic coal basin of arsenic;Discussion material sources and migration enrichment mechanism of the geochemicalbehavior of arsenic in coal, based on a comparison with the normal high arsenic coalzone geological characteristics analysis, control analysis of the role of structure,sedimentary, magmatic hydrothermal activities of arsenic in coal geology, thus revealthe geological formation mechanisms of arsenic in coal enrichment. Further deepenthe understanding of the Xinjiang coal geochemistry, environmental protection andrational exploitation of Santanghu Basin coal resources are of great significance.
