    Flexibility and use of underground medium density differences, through observation and analysis of the land on the artificial seismic waves stimulate the response, inferred underground rock formations of the nature and form of geophysical exploration methods called seismic exploration. Seismic exploration is the investigation before drilling oil and gas resources in an important means in the coalfield and engineering geological exploration, regional geological studies and research in the crust, but also been widely used.

            In the artificial surface to stimulate seismic waves, spread to the underground, when the different nature of the medium rock interface, seismic reflection and refraction will occur in the surface or wells used to receive such a detector seismic waves. The seismic signals received and the source of, the location of detection points, seismic waves through the underground strata of the nature and structure. Based on seismic processing and interpretation of records, it may be inferred that the nature of underground rock formations and patterns. Seismic exploration in the hierarchical level of detail and accuracy of the survey, are superior to other geophysical exploration methods. Seismic exploration of the depth of Shushi Mi from the general to dozens of kilometers.

            Source explosion is widely used in seismic exploration of Fei Rengong source. Has developed a series of ground source, such as a heavy hammer, continuous vibration sources, such as pneumatic source, but the regular use of the land seismic exploration is still an important source of explosives. In addition to marine seismic source of explosives, but also widely used air guns, guns and steam EDM detonated gas, and other methods.

            Seismic exploration is the investigation before drilling oil and gas resources of the important means. In the coalfield and engineering geological survey, regional geological studies and research in the crust, seismic exploration has been widely used. Since the 1980s, for certain types of metal ore exploration has chosen to use the seismic exploration methods.
