Optimization of detection methods and application for hidden goafs in Bayan Aoban fluorite mine,Inner Mongolia
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.
