邢台章村四井地质构造研究

Geological structure of Zhangcun sijing minefield

通过对邢台矿区章村煤矿四井多年勘探和生产中获得的大量地质资料的分析研究,得出该矿地质构造以NEE向正断层发育为特点。断裂构造平面展布形式以平行式、雁行式和"入"字形为主,剖面上构成阶梯状和地堑地垒组合形式。小断层具有密集成带的特点,且方向性明显,成为影响煤矿生产的主要地质因素。在此基础上对未采区断裂构造的发育进行了初步预测。

This paper analyzes and researches geological materials acquired from several years＇ exploration and exploitation of Zhangcun Sijing Minefield, drawing a conclusion of the features of geological structure at the mine are that normal faults grow very well, their main distribution direction is NEE, which is the main geological factors affecting coal production. Extension direction of faulted structure is mainly in the form of parallel fault-plane, flying geese pattern, pattern as ＂λ＂ ,and pattern in profile is a ladder and graben or horst. The characteristics of small faults are coarctation and zonation with clear direction. Based on characteristics of geological structure, faulted structures in the unmined sections are forecasted.
