Description

technical field

[0001] The invention relates to a starting device for data acquisition in the technical field of geophysical exploration, in particular to a multi-mode starting device for seismic data acquisition. Background technique

[0002] In the past two decades, the work of energy conservation has been placed in a very high position, and the mining of underground resources is required not to waste as much as possible. Therefore, with the gradual increase in the requirements for the detection of geological structures, seismic instruments, signal processing methods and technical means have been developed. Great progress has been made, but the starting device used in seismic instrument data acquisition is relatively simple, and not much research has been done. When seismic instruments are used for detection on different occasions, the method of generating the seismic source should be carried out according to different geological structures. There are different vibration m...
