通二井田位于峰峰煤田鼓山以西。该区地形丘陵起伏,地层出露不良,仅见零星露头。本井田所在区的地质构造为一东西两翼翘起的向斜(图1下),北北东向断层比较发育,特別是两翼翘起的地方,因挠曲剧烈,地层突然变陡,勘探过程中,断层易于联错。为了总结勘探经验,提高对该区地质构造规律的认识,我们于1973年,对本井田及其扩大区张家庄井田开采揭露的地质构造资料进行了分析研究,与1964年原勘探的地质构造图纸进行了对比。工作表明,对地层走向、倾角及断层面走向掌握不准,都会引起断层推断的误差。兹分述如下。
Pass two mine fields located Fengfeng coalfield west of Gushan. The terrain hilly area, strata exposed poor, only to see scattered outcrop. The geological structure of the area where the mine is located is a tilt-raised syncline (shown in Figure 1). The north-north-easterly faults are relatively developed, especially where the two wings are tilted. Due to the violent deflection, the stratum suddenly becomes steep and the exploration process In the fault is easy to mistake. In order to summarize the exploration experience and improve the understanding of the laws of geological structure in the area, we conducted an analysis and study on the geological structural data exposed in this mine field and its expanding Zhangjiakou minefield in 1973, and compared with the geological exploration drawings of the original exploration in 1964 Compared. Work shows that the direction of the formation, inclination and fault plane are not allowed to grasp, will lead to fault inference error. It is divided as follows.
