中文摘要:
      采用高密度电法与地质雷达组合方式对某拟建工程场地进行了探测,以揭露巷道为突破口,在分析巷道及采空区物质构成及空间形态的基础上,将老煤窑巷道或采空区等效为半充填型空洞(洞穴)目标体,并分析了地球物理响应特征,结果显示:地球物理异常辨识标志明显,即高密度电法为上下相邻的高低阻圈闭异常,高低阻分界对应巷道或采空区底板,高密度电法低阻异常区(坍塌填充区)对应地质雷达多次强反射区,而高阻异常区(空洞区)地质雷达则反射不强或无反射;后期钻探证实了该推断,对物探人员开展类似工作有实际指导意义。
英文摘要:
      Using high density resistivity method and geological radar combination of certain for the detection of the project,to reveal roadway as the breakthrough point,on the analysis of the roadway and gob material composition and space form,on the basis of the old type coal roadway mined-out area equivalent to half a pack or empty (cave) targets,and analyzes the geophysical response characteristics,the results showed: Geophysical anomaly identification marks clearly,namely the high density resistivity method is next to abnormal high and low resistance reservoir,corresponding or goaf roadway bottom boundary between high and low resistance and high density electrical method low resistivity anomaly area populated area (collapse) corresponding geological radar strong reflection area for many times,and high resistance anomaly (hollow) geological radar reflection is not strong or no reflection;Later drilling confirmed the conclusion,which has practical guiding significance for geophysical prospecting personnel o carry out similar work.
