| 摘 要： | 王洼勘探区位于固原含煤区，勘探区整体为一走向近南北至北北西、向东倾伏的单斜构造，地层走向与构造的走向基本一致。在详查阶段确定区内发育王洼背斜、范新庄向斜。通过王洼扩大勘探后，根据新增钻孔资料分析，区内西南部发育一条走向NNE，倾向W的正断层（F7），倾角60°～80°，由南部延伸至勘探区，落差0-200m，尖灭于中北部的第4勘探线附近。据此认为原定的王洼背斜、范新庄向斜实为断层F7在断裂过程中所引起的牵引变形。

| Abstract: | The Wangwa exploration area is located in the Guyuan coal-bearing zone, as a whole, the exploration area is a monoeline with near NS to NNW strike and plunging east, stratigraphic strike is basically identical with structural strike. The Wangwa anticline and the Fanxinzhuaug syncline have identified during preliminary exploration stage. Through extending exploration of Wangwa exploration area, based on newly drilled borehole data analysis, a normal fault （F7） with NNE strike, dipping west and dip angle 60°- 80°, throw 0-200m has found in southwestern exploration area, extending from south into the exploration area, pinch out near the No. 4 exploration line in middle north part. In view of the above, the paper concluded that the originally identified Wangwa anticline and Fanxinzhuang syneline are tractive deformations during the F7 fracturing process actually. |
