宣汉县添子城复背斜南西翼矿区地质构造特征分析

Analysis of Geological Structural Characteristics of the Southwest Wing Mining Area of Tianzicheng Complex Anticline in Xuanhan County

本文综合分析了添子城复背斜南西翼矿区的褶曲、断层等构造形迹特征,研究了构造体系复合特征。研究发现,龙洞背斜、三墩向斜是对本矿区起主要控制作用的地质构造;断层对区内煤层的影响明显,次级褶皱影响较小;矿区显示的各种构造形迹主要属于北西向构造带的构造。本次分析成果对今后该区域进一步工作及其他地质工作有明确的指导作用。

In this paper,the structural features of folds and faults in the south-west wing mining area of the Tianzicheng compound anticline are comprehensively analyzed,and the composite features of the structural system are studied.The study found that the Longdong anticline and the Sandun syncline are the main geological structures controlling the mining area;the influence of faults on the coal seams in the area is obvious,and the influence of the secondary fold is small;the various structural traces shown in the mining area mainly belong to the structures of NW-trending structural belts.The results of this analysis have a clear guiding role for further work in the region and other geological work in the future.
