采空区探测高密度电阻率法的应用

摘要

高密度电阻率法由常规电法演化而来,其电极排列类型多,应用范围广。本文以北京地区的地下采空勘查探测为例,论述了高密度电阻率法的测线布置、电极排列,到数据处理、图像解释等技术方法。通过实地钻孔验证,说明探测结果准确,为采空区评价提供了可信的基础数据。%The high density resistivity method is evolved from a conventional electrical method. The method has lots of types of electrode arrangement, and is applied in a wide field. This paper takes Beijing underground gob area as an example, and analyzes the method＇s survey line layout, electrode arrangement, data processing, image interpretation and other technical methods. According to the field drilling testing results, it considers that the detection result is very accurate, and can provide a credible basis data for the gob area.
