陆相含煤地层的煤层对比问题比较复杂。我们通过追踪煤系露头和几条勘探线钻孔资料的分析,研究了河东煤田中部,即山西中阳、离石、柳林以北到临县一带的煤系岩相旋回和煤层的变化规律,并用于煤层对比。实践证明,用岩相旋回方法对比陆相煤系,仍为一种有用的方法。一、地质概况河东煤田位于山西省吕梁山脉的西麓。除东部边缘具有北东向的断裂外,区内构造简单,地层倾角一般在10°以内。
The problem of coal seam contrast in continental coal-bearing strata is rather complicated. By tracking borehole data of outcrops of coal measures and several exploration lines, we studied the variation of coal-bearing facies cycles and coal seams in the central Hedong coalfield, ie, from Zhongyang to Lishi in Shanxi Province, from north Liulin to Linxian County , And used for coal seam contrast. Practice has proved that the use of facies cycle facies comparison of continental coal, is still a useful method. First, the geological overview Hedong coalfield is located in Shanxi Province Luliang mountains in the western foot. In addition to the northeastern eastern margin of the fault, the structure is simple, strata dip generally within 10 °.
