Abstract

The article considers a methodology for creating a geodetic framework during the development of the large-scale Zhylandy group of deposits in the Ulytau region of the Republic of Kazakhstan. This methodology is based on the use of satellite measurements to determine the planimetric coordinates of a geodetic network. This approach makes it possible to establish a geodynamic polygon (GDP) during subsoil development and to transfer design solutions into the field.

The article proposes a relevant principle for forming a geodynamic polygon based on the use of a local flat surface with topocentric coordinates. In addition, algorithms for transforming coordinates from a geocentric system to a topocentric system are presented, along with the obtained practical results. A qualitative analysis of the advantages of the proposed methodology compared with the application of the zonal Gauss–Krüger coordinate system is provided.

The research results have been implemented at operating mining enterprises during the execution of the projects “Integrated monitoring of slow deformation processes of the Earth’s surface during large-scale development of deposits in Central Kazakhstan” and «Development of a highly efficient methodology for monitoring the geotechnical state of a rock mass to assess and forecast deformation processes during deposit development» and have also been used in the educational process of Satbayev University.
