PROCEDURE OF REFERENCING AND ADAPTATION OF SEISMIC TRANSMITTERS TO LOCALITY Russian patent published in 2003 - IPC

FIELD: seismology. SUBSTANCE: procedure can find use for determination of coordinates of points of installation of seismic transmitters with adaptation to properties of ground in points of their installation. Range is established by propagation time of acoustic wave from blast of explosive charge in point with known coordinates to installed seismic transmitter. Procedure is based on property of constancy of speed of acoustic wave that alters insufficiently because of air temperature and humidity in contrast to speed f propagation of seismic wave that can change substantially depending on humidity, temperature and density of ground. Speed of propagation of seismic wave is found simultaneously by time of delay between seismic and acoustic waves which allows electron circuit processing seismic signals to be adapted to properties of ground in point of installation of transmitter. EFFECT: raised quality of processing of received signals. 8 dwg
