Determination of Critical Deformation and Destruction Parameters of the Zhelezny Open Pit Rock Mass (JSC Kovdorsky GOK) Based on IBIS FM Ground Radar Data

Abstract

It is impossible to predict the state of rock mass without determining the ultimate values of deformation parameters. A widespread method for their determination is to identify empirical patterns obtained by analyzing the in situ observation results. One of the most effective tools of the slope and pit wall stability monitoring today is the use of ground-based interferometric radars. In Russia, radars have come into use relatively recently, about 5 years ago, and today this monitoring method is gaining popularity despite quite expensive equipment. This is due to its apparent advantages over other methods: the capability to produce a large amount of information on the rock mass movement in a short period, 24 × 7 monitoring of the rock mass conditions in all weathers, highly accurate observations, etc. The paper presents the data on registered rock falls in the open pit of the Zhelezny mine recorded by the IBIS FM radar (IDS, Italy) and the results of determination of critical parameters.
