| 摘 要： | 根据宜洛煤田深部勘探区的地层、煤层及总体构造特征,分析了断层、褶皱等构造因素对主要可采煤层二1煤层赋存和分布的控制作用。研究认为煤层的分布规律受聚煤环境及后期构造活动的改造等综合作用的控制,李沟向斜及沙坡背斜控制煤层埋深,北西西向断层使南部煤层抬升遭受剥蚀,形成大面积无煤区,近南北向断层使煤层的连续性遭到破坏。构造控煤因素的研究为矿井建设开发布局、安全生产提供了地质依据。

| Abstract: | Based on strata, coal seams and general structural characteristics in deep part exploration area of the Yiluo coalfield, analyzed controlling effects of fault, fold structural factors on main mineable coal seam II2 hosting and distribution in the area, expounded impacts from structural coal controlling factors on coal II1 thickness and coal quality. The study has considered that the distribution pattern of coal seams has controlled by integrated actions of coal accumulation environment and subsequent structural activities. The Ligou syncline and Shapo anticline controlled coal seam buried depth;NWW faults made southern part coal seams elevated, denuded and formed large barren area, near NS faults made destruction of coal seam continuity. The study of structural coal controlling has provided geological basis for mine construction, exploitation layout, safety in production. |
