LOCATING DISTURBANCES IN A MINERAL SEAM BY SEISMIC HOLOGRAPHIC METHODS |
摘要 |
Faults in an underground coal seam are located by firing a shot at one point in the seam and detecting the seismic reflections in an array of geophones. Signals from the geophones are recompressed and analyzed according to an exponential formula to give a holograph of the seam and to predict the fault pattern. |
