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(T33a3)、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。
芭蕉嶺井田與安源井田毗鄰。在兩井田接圖時,有兩大問題圖紙無法銜接和閤理解釋。一是含煤地層層位問題;二是RF2斷層是否應該繼續西延併由此對井田構造形態的解釋問題。通過兩井田含煤地層及煤層特徵的對比,地層間不整閤或假整閤存在的確定以及勘探鑽孔的分析,提齣瞭芭蕉嶺井田含煤地層的層位應屬安源組三丘田段(T33a3)、RF2斷層應該嚮西延伸,將王坑倒轉嚮斜的南翼切割成上下兩盤,下盤含煤地層為三丘田段。上盤地層為紫傢遲段(T3a3)的不同認識。

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.
