Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Karaganda region is located on the most elevated central part of the Kazakh Upland -Saryarka. This region is a peculiar and geomorphologically heterogeneous, sharply elevated natural country. The paper considers the natural conditions of the Karaganda region and thematic factors of the physical-geographical, geological, engineering geological, ecological-geological directions of research, for the preparation of the foundations for the compilation of an engineering-geodynamic map for the assessment and typification of geo-risks, as well as their geonomization. A series of methodological requirements have been developed as monitoring criteria for a comprehensive assessment of hazards, risks and vulnerability of the population and the territory to the processes of long-term mining by open-cut and underground coal mines in the study area. Of all the geological structures, the most thoroughly studied is the Karaganda synclinorium, elongated in the sublatitudinal direction. The middle part of the synclinorium is occupied by a coal basin. A geological and ecological basis for compiling a new engineering-geological and ecological-geological map for assessing and typing geo-risks is presented, which takes into account coal-bearing formations, coal grades, mining areas and geo-risks manifested in 2020. Data have been developed for the certification of geo-risks of various types that appear as a result of the continuation of the development of a coal deposit in order to minimize their negative impact.
