断裂构造的空间形态研究是地质动力区划工作的重要内容之一。为了确定鹤岗矿区兴安井田断裂构造的空间形态特征,利用EH4连续电导率剖面系统对其进行了电导率测量。测量表明,在本研究区域内,断裂构造表现出明显的高阻特征,与区域背景形成强烈的反差。通过EH4电导率剖面测量,确定了某裂带在近地表其视倾角为62°,向下延伸倾角逐渐变大,至-710m近于直立;Ⅳ—3断裂带视倾角约为75°,向下延伸至-800m。EH4测量结果确定了断裂构造的空间形态,为进行地质动力状态研究奠定了基础。
The study of spatial structure of fault structure is one of the important contents of geological dynamic zoning work. In order to determine the spatial morphology of the fault structure in Xing’an Minefield in Hegang Mining Area, the conductivity of EH4 continuous conductivity profile system was measured. The measurements show that in the study area, the fault structure shows obvious high-resistance characteristics, forming a strong contrast with the regional background. According to the conductivity profile of EH4, the apparent dip angle of a fault zone near the surface is 62 °, and the dip angle of downward extension becomes larger gradually to -710m. The apparent dip angle of fault zone Ⅳ-3 is about 75 °. Under extended to -800m. EH4 measurements confirm the spatial structure of the fault structure and lay the foundation for the study of the geodynamic state.
