Abstract
The measuring and computing system consisting of two sensors was deployed to monitor the geomechanical state of the near-fault zones of tectonic faults at horizons + 380 and + 405 at the quarry of the Zarnitsa diamond pipe in 2019. The monitoring was carried out from 02.10.2019 to 28.11.2019. The measurements demonstrated alternating displacements of geoblocks in the near-fault zones up to 3 mm in size, which lead to rock caving along tectonic faults of the side slopes of the quarry.
