摘要

以翟镇煤矿2#煤层开采过程中获得的断层资料为依据,结合区域构造背景,分析了井田内小断层的成因特征及分布特征。研究发现,井田经历不同时期的构造应力场后形成了4组方向的断层构造,后期形成的NE向断层切割较早发育的NW向断层,井田内断层密度分布不均,其中,高密度区主要分布在井田东部。通过断层特征分析总结出井田内小断层具有方向性、分区性、分级控制性和成带性等发育规律。
        According to the fault materials obtained in the mining process of No.2coal seam in Zhaizhen Coal Mine,combined with the regional tectonic setting,the features of formation cause and distribution of small faults were analyzed.The results showed that there were four groups of fault structure in different direction formed after tectonic stress field of different periods,the fault of northeast direction formed in the later stage cut the fault of northwest direction formed earlier.In the coalfield,the density of faults had an uneven distribution,and the high density area mainly existed in east part of the field.Through the analysis of fault features,it found that the small faults were directional,divisional,grading controlled and zonal.
