(NIGTC FEB RA)//vitstepanov@yandex.ru MERCURY GOLD DEPOSITS The geological and structural position, mineralogy and composition of native gold of gold deposits and placers, in which mercury gold predominates, are considered. Native gold in ore deposits and paleoplacers is usually fine and dispersed, while in modern placers it is large to small nuggets. Gold in ore deposits and placers has a high breakdown and mercury admixture from 1-2 to 10-15%. A significant admixture of mercury in native gold indicates the simultaneous participation of both elements in the ore-bearing fluid and raises the question of the role of mercury in the formation of gold deposits. Keywords: mercury gold, gold deposit, gold-mercury formation, paleoplacer. Р.3-10 |

(St. Petersburg State Technological Institute (Technical University)//rufat.abiev@gmail.com OVERVIEW OF AGITATORS USED TO SUSPEND SOLIDS IN THE URANIUM PRODUCTION PROCESS The article provides an overview of various types of agitators used to suspend solids in the process of chemical precipitation of uranium. The requirements imposed by the technological process, as well as the advantages and disadvantages of traditional mixing devices for pulps mixing in the mining and metallurgical industry have been studied. As an alternative to traditional forms of stirrers, a new type of conical mixer is being considered, which has a high potential for implementation, since it ensures the formation of large flakes with lower energy consumption. Keywords: stirring device, suspension, uranium, precipitation, energy efficiency. Р. 31-36 |

(MGRI-RGGR)//solovyevnv@mgri.ru METHOD OF STUCK RELEASING AND LIFTING OF DRILL, AND CASING STRINGS WHILE DRILLING AND REPAIRING WELLS The method of extracting the free part of the stuck pipe string from the well using a special device for unscrewing pipes in the well (URT) during drilling and workover of deep wells is described, which makes it possible to start work on extracting pipes by the unscrewing method without additional preparatory work. Researches and design and technological studies of the device (URT) are given, which allows to significantly increase the efficiency of using this method. The data of experimental and production studies are also given.

(Bryansk State Technical Universit)//atamanova_2812987@mail.ru METHODOLOGY OF FORMING AN INFORMATION MODEL FOR PLANNING GEOLOGICAL EXPLORATION BASED ON THE ONTOLOGICAL APPROACH Currently, more and more attention is being paid to the processes of digitalization of individual industries and the national economy. In this sense, the geological industry is no exception. Digitalization of the geological industry, in our opinion, should be based on the creation of information data models capable of aggregating significant arrays of heterogeneous and heterogeneous information, as well as on machine learning methods and algorithms capable of implementing the functionality of decision support systems in this industry. The specifics of the industry require the development of the structure and composition of an ontological model capable of semantically integrating information resources. This article discusses one of the particular issues within the framework of the complex task of creating an ontology and thesaurus of geological information resources, namely, the methodology of forming an information model for planning geological exploration based on the ontological approach. Keywords: information and analytical system, geological study of the territory, mineral resources, reproduction of mineral resources, geological information resources, geological and economic monitoring, ontological engineering.

It was carried out in four stages. Initially, the Essentuki salt-alkaline springs did not arouse interest. The turning point was 1823, when A.P. Nelyubin investigated them. Since that time, attention has been paid to the source No. 17. It has become one of the main sources in the treatment of various diseases. Keywords: Caucasian Mineral Waters, salt-alkaline springs, Essentuki No. 17. P.53-61 |
