Abstract
Faults in a mineral seam are located by an in-seam seismic technique which involves locating shots and detectors in the seam and firing the shots sequentially. The detectors pick up the reflections of the shots from faults and a common reflection point is determined by analyzing the seismic traces from the detectors.
