ASSESSMENT OF DEFORMATION AND RADIATION STATE OF ADJACENT TERRITORIES OF THE DEPOSIT “KARAZHYRA”

Abstract

The Semipalatinsk Test Site (STS) has been the site of numerous nuclear tests, resulting in significant environmental contamination by radionuclides. Additionally, the Karazhyra coal deposit is currently being developed within this territory. According to the legislative acts of the Republic of Kazakhstan, the entire STS area is presently classified as reserve land. Ensuring the safety of this territory for economic activities remains a critical challenge, necessitating an assessment of its deformation state and a forecast of radioecological situation. To address this issue, comprehensive monitoring approach-integrating geodetic, satellite, and radioecological methods-is required to evaluate the area and provide recommendations for its potential economic use. Purpose of the work. This study aims to develop a geodetic monitoring framework for the Karazhyra coal deposit, located within the Balapan test site, where underground nuclear explosions were conducted. The objective is to assess deformation state of territory and determine cadastral value of contaminated land plots. Results. The paper presents results of scientific work conducted by the authors on geodetic monitoring of deformation processes on the earth’s surface, as well as zoning of contaminated lands with the establishment of their cadastral value. Scientific novelty. Method for creating geodynamic polygon is proposed. This approach enables effective monitoring of land deformation dynamics and allows for adjustment of land assessments based on contamination levels. Practical significance. Proposed geodynamic monitoring approach for assessing the SNTS territory is applied in master’s and PhD dissertations and integrated into the educational processes of the Kazakh National Research Technical University (KazNITU), the Eurasian National University (ENU) and the International Educational Corporation (IEC).
