山西平朔矿区某井田断裂构造发育规律研究

基于平朔矿区一井田地质报告和勘探结果，归纳总结出了研究区断裂构造的发育规律，发现断层主要表现为高角度正断层，方位以NNW、NNE 为主，近EW 次之，井田内小断层较为发育，断层落差大多集中在10 m 以下。研究区内发育的断层剖面组合形式为半地堑型、阶梯状组合、地堑组合以及堑垒相间的形式。根据井田地表的节理统计分析，研究发现井田内断层的展布以NNE、NNW 为主，与地表节理走向密切相关。

Study on development law of fault structure in a mine shaft of Pingshuo mining area in Shanxi Province

According to a report of geological exploration results and analysis of Pingshuo mining area，the authors summed up the development rules of the fault structure in the area，and found that the fault was mainly manifested in the high angle normal fault.The fault orientation was mainly dominated by NNW，NNE，and EW to the second. Small faults below 10 m were found in a higher frequency. Half graben，step micro-faults，rift valley，juxtaposition of uplifted and depressional units were found in the area. Finally，it was found that the distribution of faults in NNE and NNW in a high frequency，and was closely related to the surface of joint strike.
