摘要
桑峨井田主要含煤地层为上石炭统太原组和下二叠统山西组,其太原组含煤系数4.02%,山西组含煤系数11.34%;太原组属潮坪—碳酸盐台地沉积,主要可采煤层为9号煤层,厚度较大,为大部可采的稳定煤层;山西组为一套以河控三角洲平原环境为主的含煤沉积,主要可采煤层为2号、3号煤层,其中2号煤层为全区可采的稳定煤层,3号煤层为大部可采的稳定煤层;主要煤类为贫煤,煤质较好,具有较高的开采价值。通过对可采煤层的赋存特征及其沉积环境研究,对本井田资源的开发利用具有积极意义。
The main coal-bearing strata in Sang'e minefield are Upper Carboniferous Taiyuan Formation and Lower Permian Shanxi Formation.The coal-bearing coefficient of Taiyuan Formation is 4.02%,and that of Shanxi Formation is 11.34%.Taiyuan formation belongs to tidal flat-carbonate platform deposit.The main minable coal seam is No.9 coal seam,which is a stable coal seam with large thickness.Shanxi Formation is a set of coal-bearing deposits dominated by river-controlled delta plain environment.The main minable coal seams are No.2 and No.3 coal seams.Among them,No.2 coal seam is a stable coal seam that can be mined in the whole area,and No.3 coal seam is a stable coal seam that can be mined in most areas.The main coal is lean coal,which has good quality and high mining value.Through the study of the occurrence characteristics and sedimentary environment of the mineable coal seam,it is of positive significance to the development and utilization of the minefield resources.
