Application of Complex Geophysical Prospecting in Gob Exploration

To investigate the gob distribution underlying industry square on Nanyang road in Silaogou Mine, the complex geophysical prospecting combined 2D seismic method with high density electrical method was utilized for the gob exploration. Firstly, five abnormal gob areas were selected by 2D seismic method while two abnormal gob areas were found by high density electric method. Then, the gob distribution was concluded by combining outcomes of two geophysical techniques.
