METHOD OF SEISMIC PROSPECTING Russian patent published in 1994 - IPC

FIELD: civil-engineering survey. SUBSTANCE: during the seismic prospecting the linear source of seismic oscillations is disposed parallel to the non-longitudinal line of inspection at a definite distance. Temporary corrections for the velocity of detonation of the linear charge are determined on the basis of equality of the recording time of the sound wave in the check points. The distance between the source and the inspection line is chosen on the basis of securing the recording of the first phases of effective waves connected with the upper part of the cut in the periods of time less than the recording time of the sound and superficial waves. EFFECT: enhanced accuracy of measurements. 3 dwg
