摘　　要：选取黄河北煤田的断层为研究对象,通过对断层勘测数据进行统计,结合地质构造应力分析等理论,分析得出黄河北煤田的构造发育规律性和构造应力场特征。其中黄河北煤田褶皱构造简单,断层构造复杂程度中等,断层优势走向以NW—NNW向和NE—NNE向为主,断层优势倾向为NE向和SW向。综合分析黄河北地区的局部构造应力场具有多期多属性的应力特征,按构造发育展布规律可归纳为两期主要构造应力场。第一期的主压应力方向为NW—SE向,晚期发生右旋剪切作用,第二期的主压应力方向为NE—SW向,晚期发生右旋剪切作用。通过多年勘探发现黄河北煤田富集多种矿产资源,且研究发现各类资源的富集均受构造的影响和控制。研究结果对该区矿产的勘探开发具有理论指导意义。The paper has studied fault development features in the Huanghebei coalfield.Through statistics of fault exploration data,combined with theories of geological structural stress analysis etc,have analyzed structural development regularity and structural stress field features.In which,folded structure in Huanghebei coalfield is simple,complexity of faulted structure medium,fault preponderant strikes have mainly NW-NNW and NE-NNE,while preponderant dips NE and SW.Comprehensively analyzed local tectonic stress field in the region has multiphase and multi-attribute stress features,according to tectonic development and distribution patterns can be induced into two phased main tectonic stress fields.The principal stress direction of first phase is NW-SE,in later stage has happened dextral shearing;principal stress direction of second phase is NE-SW,in later stage happened dextral shearing.Through exploration in years has found multiple mineral resources enriched in Huanghebei coalfield,while the enrichment of various resources are all impacted and controlled by structures.Studied results have theoretical guidance significance to mineral resources exploration and exploitation in the region.
