| 摘 要： | 徐庄滑动构造是河南省荥巩煤田主要构造之一,对区内二1煤层的赋存特征影响较大。经对大量计河井田勘查资料分析,发现滑动构造破碎带厚度与其下伏二1煤层厚度相关程度较高,表现为两者在中、浅部厚度变化大,并沿倾向呈薄、厚相间的条带状展布,大致在二1煤层-300m水平附近,滑动构造破碎带厚度变薄尖灭,煤层厚度亦相应变小且趋于稳定。通过对钻孔数据的回归分析,认为二1煤层厚度与其上滑动构造破碎带厚度呈正相关关系,这一结论对后期矿山开发中工作面的布置及做好安全防范措施有指导意义。

| Abstract: | The Xuzhuang gliding tectonics is the one of major structures in the Xinggong coalfield, Henan province and its fracture zone thickness has rather high degree of correlation with underlying coal seam II1 thickness according to analyses of abundant exploration data from the Jihe minefield. The both appeared as larger thickness varying in middle and shallow parts and presented as thin and thick interbandings. Approximately near the coal seam IIl -300m level, thickness of fracture zone is getting thinner and wedged out, coal seam thickness getting smaller correspondingly and tending to stabilized. Through drilling data regression analysis, considered that the thickness of coal seam II1 presents positive correlation with the thickness of overlying gliding tectonics fracture zone. The conclusion has guiding significance on working face layout and safety precautions in later stage coalmine development. |
