Rock burst | geophysics | Britannica
Rock bursts, in which rocks are ejected suddenly in deep pits or tunnels, are caused by increase of stress in the surrounding rocks. Experience in mines shows that an increase of small shocks detectable by highly sensitive geophones—portable seismometers for field use—generally indicates a rock…
What is Rock Burst? - Definition from Trenchlesspedia
2020年2月5日 · Rock burst occurs when the stored elastic energy that is accumulated by the elastic strain of the rock, exceeds the storage limit. Seismic refraction and other tests are carried out to determine the sub-surface geology and in-situ stress in rocks. Reflection seismology is also used to image the earth's sub-surface geological structure.
