Seismic Refractive Index Method Of Mining

Seismic Method an overview ScienceDirect Topics

Seismic methods involve measuring the propagation of seismic waves through earth materials. In seismic surveys, seismic waves radiate outward from a sound source at the surface, which can be an explosive charge or a mechanical impact. The refraction technique uses a long array of geophones to sense refracted waves, and the reflection technique uses a condensed array

Earth exploration Earth exploration Seismic refraction methods: Seismic methods are based on measurements of the time interval between initiation of a seismic (elastic) wave and its arrival at detectors. The seismic wave may be generated by an explosion, a dropped weight, a mechanical vibrator, a bubble of high-pressure air injected into water, or other sources.

Thus, while most refracted events have not been reflected, most reflected events have been refracted, because a refraction occurs across any velocity interface in accordance with the simple

Definition of seismic method Mindat

There are two main subdivisions of seismic operations: the reflection method and the refraction method. The seismic method has been applied to a lesser extent to elucidate mining problems, partly due to its high cost. It has been used to investigate the base of drift deposits, and drift-filled channels have been successfully outlined. Ref: Nelson
