Coal Accumulating Characteristics Research In The Bozidun Mining Area Of Wensu County, Ku Bai Coal Field, Xinjiang

The kubai coalfield Wensu County Bo Zi Dun in the mining area of the mine geological exploration data and thousands of results in combining the means, in coalfield geology,sedimentology, paleontology and theory as a guide, according to coal basin analysis ideas and procedures of Bo Zi Dun mining area geological structure, sedimentary features of coal measures strata, coal quality, a comprehensive summary of the, sedimentary characteristics in the study area in the coal bearing strata and together the United States and the characteristics of the specific research.In the study area is located in the northwestern margin of the Tarim Basin kubai coal basin in the western part of the, in Tianshan Piedmont, northern Alpine belonged to the Tianshan geosynclinal fold system. In the rest of the genus Tarim platform. Affected by the piedmont fault of the basin edge, kubai coalfield is a East-West banded basin. The basement is mainly from Upper Paleozoic Permian coalfield, the field of Carboniferous, extensive superimposed sedimentary cover, in cenozoic. Among them, in the lower Jurassic for coal formation, Triassic sedimentary basement. The coal bearing basin in Middle Jurassic taliqike formation and Nur formation kertzThe middle lower Jurassic coal bearing strata tower chick group containing, Yangxia formation and Kezi Nuer group of rock types, lithology and sedimentary structure do detailed research, and on the region containing the depositional system of the coal bearing strata division and sedimentary phase combinatorial analysis revealed the sedimentary characteristics and distribution of the sedimentary system. Also analysis the recoverable coal seam of coal and rock characteristics of. Finally, according to the relationship between the ancient structure, paleogeography and paleoclimate and evolution of sedimentary environment, summed up the Bo Zi Dun mining area of coal accumulation characteristics.
