MONITORING OF THE GEODYNAMIC STATE OF THE ZHYLANDY GROUP OF DEPOSITS

Abstract

The features of the manifestation of geomechanical processes and ways to solve them at the mines of the Zhilandinsky ore field in the Ulutau region of Kazakhstan are considered. For reliable forecasting and prevention of dangerous geomechanical phenomena in the Zhilandinsk ore field area, a geodynamic polygon has been created, which includes modern measuring complexes. Using the means of a geodynamic polygon, important patterns of behavior of an impact-prone rock mass have been identified and an indicator for assessing its condition has been substantiated. As a result of conducted research, following were created and introduced into production: geodynamic polygon (GDP) of the region;  developed designs of permanent (above-ground and underground) forced centering points (FCP), allowing to increase productivity and accuracy of observations; method for strengthening stationary quarry slopes for predicting the stress-strain state (SSS) of the mass; composition of strengthening solution from mining waste to increase stability of disturbed sections of quarry benches.Novelty of developed methods and means is confirmed by the Patents of the Republic of Kazakhstan for invention. In the context of complex geodynamic processes, further development of methods and tools for the geodynamic testing area of the Zhilandinsky ore field is required, as well as the development of innovative methods and tools for monitoring areas where dangerous geodynamic manifestations are predicted and the substantiation of their reliable precursors.
