Abstract：Taking Zhaicun Iron Mine in Laizhou City as an example,in view of the blindness and complexity of non-coal mine goaf with historical formation and responsibility loss,geophysical methods such as high-precision magnetic method,high-density resistivity method and shallow seismic method are adopted.Combined with the drilling verification results of geophysical abnormal,the plane distribution of goaf and the morphological characteristics of underground space are finely determined,and the risk areas of safety hazards are delineated.The results indicate that using comprehensive geophysical methods to finely detect historical abandoned goafs is effective and feasible.This provides a reference basis for future geophysical exploration work in the investigation of goaf in mines with historical formation and loss of responsibility.
