Abstract Goaf tends to cause land subsidence and threaten the safety of power grid operation. It is of great significance to detect the distribution of underground goaf. Traditional goaf electrical detection technology has complex control system and complicated survey line arrangement, needs many sensors and cables as well as large amounts of measurement data, and is characterized by inefficient layout and mobile measurement, and hence it is not suitable for the use of electric power field to prevent and control the hazards of underground goaf. In view of the distribution characteristics of goaf under power pole and tower, the authors designed an electrode system for goaf electrical detection. The centralized-istributed detection method can effectively reduce the number of sensors and cables for goaf detection under power pole and tower, optimize the system control, simplify the effective detection data and improve the efficiency of goaf detection.
