复杂井田的煤层对比方法探讨

铁南井田位于扎赉诺尔煤田向斜东翼的中段。从沉积环境看铁南井田位于煤田内分化的湖盆中心,而且有次一级的同沉积隆起、同沉积断层存在及由此而形成的2个旋回聚煤期的同时存在。这样形成的煤层不仅有煤层厚度、结构和层间距的连续的规律性变化,还有同沉积控煤作用造成的厚度、结构和层间距的跳变。采用常规的方法已解决不了煤层对比的问题。工作中采用了沉积模式的再恢复、主要煤岩层特征、测井曲线组合特征并结合岩相分析和同沉积断层对成煤的控制作用解决了铁南井田的煤层对比问题。

Id'a Stam Coutrast of Complex Method of Sedimentary Structures

Iron Coal Mine is located in the Southern Coalfield syncline Dalai Nur tie the middle east wing. From the sedimentary environment in the coal mine field to see Iron south divide within the lake basin center, but there are times an uplift of the same sediment, with deposition of fault existence and the resulting formation of two cycles of coal accumulation phase of the case. This is not only the formation of coal seam thickness, structure and layer spacing of the continuous changes in laws, as well as with t...
