Theoretical Substantiation and Technology of Geodetic Support of Chromite Deposits on the Case of Kazakhstan: Literature Review

The study aims to examine modern technologies and develop theoretical foundations for geodetic support for the extraction of chromite ores at the Khromtau deposit. The Khromtau deposit is situated in northwest Kazakhstan's Aktobe region, about 90 km east of the regional capital, Aktobe city. This area is a component of the dry steppe terrain that makes up a large portion of northern Kazakhstan. Research methods such as analysis, comparison, systematisation, and synthesis were used while writing the study. The analysis has identified the most important technologies necessary for successfully searching and providing chromite deposits. Geodetic work is an important part of this process, including triangulation, polygonometry, and levelling techniques. These methods allow for a more accurate determination of the examined area's geometric characteristics, which contributes to a more accurate identification of potential chromite deposits. Surveying includes planning and controlling geometric parameters in the field itself. These parameters are of great importance when developing plans for the placement of future mining operations, considering the deposit's complex mining and geological features. Filming is an integral part of the exploration of chromite deposits. It includes the creation of three-dimensional models of deposits and the surrounding area, which provides a more complete and visual representation of the geometry of the deposit.
