济宁煤田济北矿区构造展布规律分析

通过对济宁北矿区区域构造特征以及区内各井田地质资料的统计研究分析，系统总结了该矿区断层构造的发育特征和展布组合规律。研究发现：在区域上,研究区构造以断裂为主，且规模和强度较大，褶皱强度小，均为宽缓褶皱。矿区内的主要断裂有两组，一组为SN向的区域性断裂，构成井田边界，另一组为由其附生的NE向断裂，使其开采地质条件复杂化。区内NE向褶皱发育，多呈背、向斜相间分布。

Analysis on Structures Distribution Regularity of North Jining Mine Area

Through analysis on regional structural characteristics and geological statistics of mines in North Jining mining area, development patterns and distribution regularity of faults in this region have been systematically identified in this paper. It is found that faults are major structures with large scale and strength. Folds are wide and gentle with low intensity. There are two main groups of faults in the mining area. One is the fault with the trend of SN, which formed the boundary of well field, and the other is the fault with the trend of NE, which made mining geological condition complex. The folds with the trend of NE in this area developed well, and alternatively distributed as anticline and syncline.
