Abstract
The development of geomechanical monitoring of the state of near-surface arrays of quarries is an urgent task for predicting and ensuring the stability of quarry slopes. This is preceded by a detailed study of the geological and geological situation of instrument massifs, the laying of reference and working benchmarks, the methodology for measuring and analyzing the obtained displacements of instrument massifs. Particular attention is paid to the analysis of the accuracy of instrumental observations with the help of an electronic total station and an optical reflector, as well as to the identification of optimal observation schemes at the quarry, which make it possible to establish rational parameters for making measurements. The distance between the reflector and the total station is set to 500m, which allows measurements to be made within ± 3 mm. The proposed measurement technique was tested in the quarries of Kazakhstan.
