为了更好地制订“煤田水文地质勘探规范”,我们对以孔隙岩层为主的煤矿床进行了初步的探采对比工作,现小结如下: 一、地质与水文地质概况舒兰煤田沉积属新生界第三系、舒兰含煤地层、吉舒组含煤建造。煤田分布在东西向长达40公里、宽1.5～3.0公里的地堑单斜内,属东北海西褶皱带,佳伊复向斜。东为皖达山复向斜,西与松花江凹陷相邻,南为昌图复向斜,北为小兴安岭复向斜。煤田走向近北40～50°东,倾向北西,矿床西侧为古生代吉林花岗岩基盘,延展方向北50°东,呈连绵蜿延
In order to better formulate “coalfield hydrogeological exploration specifications,” we conducted a preliminary exploration and mining comparison of the coal bed, which is mainly composed of porous rock layers. The summary is as follows: I. Overview of Geology and Hydrogeology The Shulan coalfield is a sediment of the Cenozoic Tertiary, Shulan coal-bearing strata, Jiushu coal-bearing construction. Coalfields are distributed within the monocline of the grabens up to 40 km in east-west length and 1.5 to 3.0 km in width, belonging to the northeastern Hercynian fold belt and the Jiayi synclinorium. The east is Wandashan syncline, the west is adjacent to the Songhua River depression, the south is the Changtu complex syncline and the north is the Xiaoxing’anling compound syncline. The coalfield is about 40-50 ° north eastward and tends to be northwest. On the west side of the deposit is the Paleozoic Jilin granite base plate extending 50 ° north to east,
