Imaging Method of Trapped Miners Position Based on Seismic Location

It is the key for the accident relief to locate trapped miners speedily after a mine accident.The activities of the trapped miner or continuous hammering would generate a signal which would be detected by geophones placed on the surface.By studying these signals,a model was established and a seismographic record stimulated repeatedly was synthesized.Cross-correlation image was carried out by using such records.Theoretical proof that this method is feasible and positioning effect is obvious.
