The measuring means and the data processing explanation principle of this apparatus, and the advanced forecast detection experiments were studied in allusion to different mines. The results show that advanced detection apparatus DTC-150 can detect geologic formation in front of the mine excavation 100 m away, and can more accurately detect faults, rock fissures, rock broken cinctures and water-rich situation, and the collection velocity can be used to classify the wall rock. Key words: seismic exploration; mine; advanced detection; long distance; multi-wave and multi-component [1] 120 m [2] [3−5]
