| 摘 要： | 鸡西煤盆地位于三江-穆棱煤盆地群内,属断拗型盆地,煤盆地构造受区域构造格局和构造演化的控制,构造格局具有南北分带、东西分区的基本特征,结合地层沉积特征及含煤岩系展布特征分析,建立了赋煤构造单元划分方案;煤盆地可分为北部坳陷、恒山隆起、南部坳陷和敦密断裂带4个三级赋煤构造单元,北部坳陷和南部坳陷进一步划分出3个四级赋煤构造单元;区内控煤构造样式划分为2大类4种类型,以伸展和挤压为主,主要包括单斜断块、堑垒构造、掀斜断块和逆冲褶皱型。

| Abstract: | The faulted depressional Jixi coal basin is situated among the Sanjiang-Muling coal basins,the structure of the coal basin is controlled by tectonic framework and tectonic evolution.The structural framework in the area has a basic feature of NS belting and EW zoning,combined with analyses of strata depositional features and coal-bearing rock series distribution features,established coal hosting structural element partition scheme.The coal basin can be partitioned into 4 third-order coal hosting structural elements of North depression,Hengshan uplift,South depression and Dunhua-Mishan faulted zone,while the North and South depressions can be further partitioned into 3 fourth-order structural elements.The coal controlling pattern in the area can be divided into 2 classes and 4 types,extensional or compressional,including mainly monoclinal faulted blocks,horst and graben structures,tilted fault blocks and thrust folds. |
