Synchronization of overburden dumping in Bucim open pit mine in function of minimal costs [PDF]

, 2013
Overburden exploatation in open pit “Bucim” is performed from 3 (three) ore bodies, with least 2 (two) excavating zone. Overburden dumping is in 3 dump: two external and one internal.

Overburden geomechanical effects on 4D seismic response – influences of stiffness contrast, anisotropy, and geometry

, 2014
Petroleum production and CO2 storage induce effective stress changes and deformations in the reservoir, as well as in the overburden. This may be detected by 4D seismic monitoring due to the stress-sensitivity of the seismic velocities in the rocks. Here
