Radars have found relatively recent application in Russia, round the last 4 years. Today this monitoring approach becomes increasingly more employed despite sufficiently expensive equipment. Such a boost is conditioned by the decisive advantages of the approach over the other methods: it provides extensive evidence on rock mass movement for a short time, allows rock mass surveillance for 24 hours a day in any weather, ensures high observation accuracy, etc. This article presents the data on two cases of rock falls recorded in Zhelezny open pit mine of Kovdor Mining and Processing Plant by IVIS FM radar manufactured by IDS, Italy. The field observation results were analyzed, and the peak values of velocities and accelerations were determined. Based on the available information, the recommendations on setting limit deformation parameters for potentially hazardous areas of pit wall are made.
