Abstract
This article offers proposals on the geoid model grid output format to ensure convenient application of the data in investigation of geodynamic processes during underground mining. With a view to improving the national geoid model, it is proposed to use the data of the detail general coverage gravimetric survey of the area of the country. These data are obtained within a reasonable time using the airborn gravimetry technology. The research findings allow creating a set of computer programs to implement the developed procedure in terms of the experimental data processing and to prove the usability of the procedure for the preliminary modeling of the geoid for the area of the Republic of Kazakhstan.The study was supported by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan, Grant No. BR 21882366.
