摘要
The survey of mine-out collapse disasters in a complex geological environment is the key to the investigation and tackling of mine safety hazards.In order to delineate the spatial distribution of the mine-out area accurately,the authors used ground penetrating radar and transient electromagnetic methods to carry out the field work according to the site geological conditions and environmental influence factors.Based on an analysis of typical abnormal characteristics of cross sections,the authors deduced the scale and burial depth and finally arranged additional drill holes to verify the effectiveness.The result shows that the integrated geophysical methods applied to the shallow mine-out area of gold mine are highly efficient and feasible.
