Application of EH4 Electromagnetic Imaging System in Goaf detection

During the site selection process of a proposed wind farm, it was found that there was a coal field nearby and there might be a goaf. In order to avoid the goaf of coal mine and eliminate the hidden safety risks brought by the goaf to the construction, geological exploration was needed. After comprehensive consideration, the author chooses EH4 electromagnetic system to probe the research area. Through the practice of wind farm site selection project, it is proved that the detection results are accurate and the method is reliable, which provides reliable reference and effective Suggestions for the later construction of fan station.
