摘要

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.
