Research on the Effectiveness of Electrical Detection

Abstract

The detection of goaf is of great significance to the safe operation of power grid. In the traditional goaf detection technologies, electromagnetic detection method is more suitable for the detection of goaf under the transmission power line. There are many factors affect the effectiveness of the goaf detection, and it is very necessary to analyze these influence factors. In this paper, finite element analysis method has carried on the preliminary discussion to goaf detection effectiveness, and the influence of depth, size and water filling of coal mine goaf on the detection results are analyzed.
