  • Seismic exploration with disposable seismic detectors
    Patent number: 4295542
    Abstract: Seismic sources and detectors are each positioned in a series of shotholes along a course to be explored. The sources in the shotholes are activated in a sequence along the course and caused to emit seismic waves. The detectors remaining along the course sense or detect the seismic waves which are then recorded. Since the detector at each shothole has performed its function, that of sensing signals from earlier shots in the sequence, its disposal by destruction when the source in the shothole with it is activated does not impair further surveying efforts.
