To address the safety hazards associated with hidden goafs in mines,the authors utilize an array of detection techniques,including geological radar,high-density resistivity,transient electromagnetism,seismic meth-ods,controllable source audio magnetotellurics,and audio magnetotellurics.Focusing on the Bayan Aobao area in the Sunite Right Banner of the Inner Mongolia Autonomous Region,this research specifically targets the optimiza-tion of goaf detection methods for fluorite deposits.By integrating the geological and physical characteristics of the deposit with the results of geophysical exploration,it was determined that a combined approach of geological radar and high-density resistivity methods is highly effective in detecting the distribution of hidden goafs.This combina-tion successfully identified the spatial distribution of hidden goafs up to a depth of 90 m in the study area.The ac-curacy and feasibility of this detection methodology were further corroborated by drilling verification and 3D laser scanning.
