对芭蕉岭井田地层层位及主要构造的不同认识

Different understanding for Stratigraphic Horizon and Main Structure of Bajiaoling Coal Field

芭蕉岭井田与安源井田毗邻。在两井田接图时,有两大问题图纸无法衔接和合理解释。一是含煤地层层位问题;二是RF2断层是否应该继续西延并由此对井田构造形态的解释问题。通过两井田含煤地层及煤层特征的对比,地层间不整合或假整合存在的确定以及勘探钻孔的分析,提出了芭蕉岭井田含煤地层的层位应属安源组三丘田段(T3a3)、RF2断层应该向西延伸,将王坑倒转向斜的南翼切割成上下两盘,下盘含煤地层为三丘田段,上盘地层为紫家冲段(T3a3)的不同认识。

Bajiaoling Coal Field is adjacent to Anyuan Coal Field. In map interlinking of these two coal fields, there are two problems in drawings; one is the problem of coal--bearing stratigraphic horizon and the other is the interpretation of coal field＇s structural feature arising from whether RF2 fault extends west. Through corn- parative analysis of coal--bearing stratum and seam formity and prospecting bore in these two coal fields, characteristics, determination of unconformity or discon- the authors propose the coal--bearing stratigraphic horizon of Bajiaoling Coal Field belongs to Sanqiutian segment of Anyuan Colliery and RF2 fault should extend west, cutting the overturned syncline south of Wangkeng Colliery into hanging side and heading side with the coal-- bearing stratum of heading side belonging to Sanqiutian segment and that of hanging side Zijiachong sediment.
