| 摘 要： | 在阐述辽河盆地东部凹陷沙三段煤系5种沉积组合的基础上,应用煤田地质学的基本理论和方法,揭示了煤层赋存的总体特征及部分主力煤层空间发育的差异性.进而分析了同沉积断裂构造和沉积环境对聚煤的控制作用,前者表现为各赋煤区的分布明显受走向与凹陷长轴方向一致的同沉积断裂控制;后者表现为在冲积扇前与残存湖泊之间出现大面积泥炭沼泽化聚煤,而泥炭沼泽是在先期扇三角洲平原与扇三角洲前缘相邻地段及部分滨湖基础上演化而成的.

| Abstract: | Base on the statement of coal five sedimentary compositions in No. 3 coal measures of eastern depressed sand, Liaohe Basin, with the application of basic theory and method of the coalfield geology, the paper revealed the general features of the coal seam occurrence and the development difference of the partial main seam space. Then the paper analyzed the control function of the con-sedimentary fracturing structure and the sedimentary environment to the coal gathered. The con-sedimentary fracturing structure... |
