嘉禾县浦溪井田位于袁家矿区中段,其煤系地层龙潭组为一套湖沼—泻湖海湾过渡相为主的沉积,厚度14.9~335m,含煤7层,煤层总厚5.25~7.85m;根据岩性、岩相特征分为上下两段,下段为不含煤段,为泻湖相沉积,平均厚187m,上段泻湖—湖沼相沉积,平均厚137m,并形成了泥炭沼泽,形成了2、3、4、5、6、7号煤层,可采煤层为2、5、6号煤层,其中,形成于滨海沼泽地区的5煤层厚度稳定,是该地区主采煤层,下段厚度比上段厚度要大,反映了该区晚二叠世期间地壳沉降不均衡,沉积环境差异是本区找煤条件的主要控制因素。
Jiahe County Puxi Minefield is located in the middle of the Yuanjia Mining Area. Its coal-bearing formation Longtan Formation is a set of lacustrine-lagoon-bay transitional facies deposits with a thickness of 14.9 ~ 335m and 7 coal layers with a total thickness of 5.25 ~ 7.85m. According to Lithology and lithofacies characteristics are divided into upper and lower sections, the lower section is non-coal-bearing section, lacustrine facies deposition, average thickness 187m, the upper lagoon - lacustrine facies deposition, an average thickness of 137m, and the formation of a peat swamp formed 2,3 4, 5, 6, and 7 coal seams, and the coal seams are No. 2, 5 and 6 coal seams. Among them, No. 5 seam formed in coastal marsh area is of stable thickness and is the main coal seam in this area. The thickness of the lower section is higher than the thickness of the upper section Which indicates that the crustal subsidence is not balanced during the Late Permian period in this area. The difference in sedimentary environment is the main controlling factor in the coal prospecting conditions in this area.
