METHOD TO DETECT THE SEISMIC WAVE TRIGGERING TIME IN SEISMIC SURVEY AND APPARATUS FOR SEISMIC SURVEY

摘要

A method and a device for detecting the generation point of elastic wave in investigating the elastic wave are provided to increase the effect of exploration work by excluding a trigger line for transmitting a trigger signal generated from a transmission source, to a recording device. A method for detecting the generation point of elastic wave in investigating the elastic wave is composed of steps for installing a receiver array at a receiver source and the position adjacent to a transmission source(100); installing a multi-channel cable for connecting the receiver array to a multi-channel data collecting and recording device(200); recording a signal received through the specific channel from a receiver adjacent to the transmission source when the transmission source generates the elastic wave, in the multi-channel data collecting and recording device as a trigger signal(300); and receiving the refracted or reflected elastic wave signal received through the channel from the receiver installed at the receiving source, by operating a channel exchanger of the multi-channel data collecting and recording device and recording the received signal(400).
