摘要

The small coal mines seriously affect the safety of large mine production because of the cross-border illegal mining.EH-4 electromagnetic imaging system,according to depth-resistivity contour map generated by etoo-dimeusional inversion,combing with the existing coal mine geological data,can be used to conduct physical detection of unknown goaf area,determine the scope of the goaf and further provide basis for the roadway layout and mining of next stage.
