Object of  research is the group of Zhilandinskoye deposits in Central Kazakhstan.

Research purpose is to create points of  geodynamic polygon and determine their location in a single coordinate system for conducting integrated monitoring based on geodetic and innovative technologies that improve accuracy and reduce time for measuring work.

Methodology. Work uses integrated approach, including: study of mining and geological conditions, structural features, physical and mechanical properties of rocks of deposits and conducting instrumental observations based on modern methods and monitoring tools developed by authors.

           Main rsults. Article presents results of many years of research by employees of the Kazakh National Research Technical University named after K.I. Satbaey (Satbaey University) on the study of geomechanical and geodynamic processes during large-scale subsoil development in complex structural rock masses to ensure their maximum safety and economic efficiency of field development.



As a research result , following were created and introduced into production:

-  methodology for maintaining integrated geomonitoring system;

-  new method of creating geodynamic polygon in the form of local control  «bushes» of geodetic and leveling points, instead of extended leveling lines on the territory of the Zhilandinsky groups of deposits;

- constructions of permanent (ground and underground) forced centering points, which make it possible to increase productivity and accuracy of observations;

- method for predicting physical and mechanical properties of mass rocks;

- method of laser scanning during structural features studying of rock mass;

- seismoacoustic method for predicting the stress-strain state of mass;

- method and composition of solution from mining waste for strengthening weakened fractured sections of open pit side and disturbed sections of underground workings;

- base of geospatial data on ore deposits of Central Kazakhstan to create three-dimensional models of mining and geological objects, taking into account their changes in the process of subsoil development.

- monitoring of slow movements of the earth's surface on a geodynamic polygon using a GS16 GPS device with a radio modem, which made it possible to determine points position quickly and accurately in a single coordinate system.



Scientific novelty of work lies in establishing pattern of changes of in structural features and strength properties of rocks with their depth, which makes it possible to predict stress-strain state of rock mass. Created geodynamic polygon is reliable basis for organization of long-term monitoring of deformation processes during large-scale development of the Zhilandinsky groups of deposits.



Novelty of developed methods and means is confirmed by the Patents of the Republic of Kazakhstan for invention.

 Practical value. Research results have been implemented at operating mining enterprises  and used in the educational process of Satbayev University, and can also be used in constructional design and operation of mining enterprises by open, underground and combined methods to increase level of industrial safety at mines and minimize environmental risks caused by subsoil development.
