ABSTRACT:
An area of a seam is defined and a series of shot locations and detectors are arranged along one side of the area to determine reflected signals. Transmitted signals are also received from a line of shot locations on the other side of the area. The signals received are processed according to an adaptive lag-summing technique to give a map showing the geological faults in the seam.
