Journal of Mining Science Aims and scope

Abstract

The experimental version of a bidimensional measurement facility allows recording displacement of rock blocks in the normal direction relative to a fault and their shear displacement relative to one another. In 2020 the facility was deployed at Zarnitsa open pit diamond mine, and was included in the long-term geodynamics monitoring in the zone along a fault which cuts the open pit. It is found that displacements of rock blocks in the normal direction to the fault are periodic at the maximum amplitude of 3.5 mm, while the shear displacement is reversal at the maximum amplitude of 1 mm.
