对段家堡区地质构造与找煤方向的研究

Duanjiabao Area Geological Structure and Searching Coal Orientation Research

对段家堡区地质构造特征进行研究,通过对下花园煤系地层分析对比得出:段家堡区总体构造形态为轴向近东西向的向斜构造,南冀以F1段层与西黄庄井田相邻,位于断层下降盘,煤层埋藏深于西黄庄井田预计1 500 m,向斜轴部煤层埋藏较深预计1 800 m,向斜北翼抬起煤系地层被剥蚀殆尽,只残留煤系下部地层。据此推断,在向斜两翼适当部位,煤层埋藏深度适中,是开展找煤工作的有利地段。

Duanjiabao area geological structure features were analyzed in this thesis.Through analyzing and comparing Xiahuayuan coal-bearing strata,it showed that the overall structure of Duanjiabao area was synclinal structure of axial near east west direction,located in downthrown of section.Coal seam deeply buried in Xihuangzhuang coalfield and the length was expected to 1 800 m.North wing of synclinal structure lifting coal strata was fully denuded,only leaving lower strata of coal strata.Hereby,the suitable place of synclinal structure two wings might be moderate coal seam burial,where it was the favorable area of the coal working.
