Background
The seismic exploration method is one of the earliest and most widely applied methods in geophysical exploration. The geophysical prospecting method is a geophysical prospecting method which utilizes the phenomena of reflection, refraction and the like of waves generated at the interface of media due to the difference of wave impedance of different media, and people can obtain the distribution state and physical property parameters of an underground medium (geologic body) by receiving the information of the reflected waves and the refracted waves. At present, the seismic exploration method is still the main means for oil exploration, natural gas exploration, coal exploration and engineering exploration on land and sea.
Engineering seismic exploration plays an extremely important role as an effective method for searching the fields of blind faults, geological structure exploration, engineering geological investigation and evaluation, tunnel advanced prediction and the like.
