Rock movement at the Tashtagol iron-ore deposit in the course of large-scale underground blasting

The paper describes the results of studies into the processes of deformation of rock masses near protected objects and in mine workings of the Tashtagol iron-ore deposit, carried out with the conventional geodetic methods and the GPS-techniques. It is shown that rock mass movements in the periods of large-scale blasting mostly take place along flat-dipping tectonic faults and in the line of action of maximal stresses in the intact rock mass. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 3, pp. 25–33, May–June, 2008.
