天安六矿三水平西翼戊8煤层赋存状况研究与分析

Research and analysis of occurrence condition of the third level west wing No.戊 8 coal seam in No.6 Mine of Tian'an Mining Industry

根据三水平西翼戊8煤层范围内大量钻孔以及井下采掘揭露资料,研究分析了西翼戊8煤层赋存状况,得出该煤层为结构简单,自西向东呈条带状逐渐变厚的较稳定煤层。结合六矿整体地质构造情况进行分析,认为由锅底山断层和郏县断层引起的地壳不均衡沉降是造成西翼戊8煤层变化的主要原因。

According to a large number of drilling and underground mining expose data of the third level west wing No. 戊 8coal seam in No. 6 Mine of Tian＇an Mining Industry, the coal seam situation was studied and analyzed, the coal seam with simple structure, becomes stripped and thick from west to east. Combined with geological condition of No. 6 Mine, Guodishan fault and Jiaxian fault caused by crustal uneven subsidence is the main reason of the west wing No. 8 coal seam variation.
