Abstract

One of the critical task in open pit mining is geomechanical control of rock mass. Such control includes different activities and up-to-date equipment. The key factor is organization of integrated geomechanical monitoring using radar systems. The leading manufacturers in this area are Italy, Australia, South Africa and China. In view of terminated supply of equipment from Italy and Australia to Russian mines because of sanctions, Chinese products took their places. The article describes organization of a geomechanical service at a mine, compares the radar systems manufactured by Italy and China, determines their peculiarities and differences, and points at essentiality of integrating information from different sources within a single all-in-one information platform. Radars have almost the same characteristics, except for the resolution power, which is higher in Chinese radars. The total cumulative displacement was 24 mm in radar MPDMRHSM and 29 mm in radar IBIS ArcSAR. The difference can be explained by the different angular coverage of the displacement domain, by the error in the domain delineation by an operator, and by the different levels of detail of the radars. The comparative analysis of the displacement velocity graphs per time stages shows insignificant deviations in times and in absolute velocities, which is also explainable by the different angular coverage of the displacement domain, by the error in the domain delineation by an operator, and by the different levels of detail of the radars.
