In this article, we present the results of the RMR characterization of the rock mass and the numerical modeling by the finite element method (FEM), under the conditions of the Djebel El Ouahch tunnel, Constantine (Algeria).The RMR system is a useful tool for characterization of the rock mass quality and establishing the appropriate support system. For poor rock (Class IV), the excavation should be top heading and bench 1.0 m – 1.5 m advance in top heading. Support should be installed concurrently with excavation, 10 m from face. Rock bolting should be systematic with 4 m – 5 m long, spaced 1.5 m – 1.5 m in the crown and walls with wire mesh, Shotcrete of 100 m -150 mm in the crown and 100 mm in sides. The steel sets should be light to medium ribs spaced 1.5 m only when required. The rock mass consists of generally poor rocks with average stand- up time of 10 hours for 2.5m span with mass cohesion ranges between 100 kPa – 200 kPa and rock mass friction angle ranges from 15° to 35°. The FEM project due to its precision calculates the safety factor and evaluates the principal deformations and displacements of the rocks mass .The originality of this work lies in the use of two different approaches , the RMR system and numerical method (FEM) for analyzing the quality and evaluation of the deformations and displace- ments of rock mass .This method has become a very common practice in underground mining excavation design.This study illustrates that the results obtained by RMR of the argillite rock mass in the case is 28.00 ,ranging from 21.0 to 40.0 classified as Class IV (Poor Rock), while the results of FEM reveal that in accordance with the poor quality of the rocks, large deformations and displacements were observed around the underground mining excavation, which can be at the origin of the ruptures. The value of the safety factor of the order of 0.95 to 1.24 shows the instability of the excavation, and the appearance of very considerable hazard zones in the argillite layer. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"14 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87893210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indirect financing infrastructure forms one of two groups of financial infrastructure. These patterns are characterized. The banking infrastructure is the most developed component of the financial infrastructure not only in the studied region, but also at the national and global levels. Regional factors, along with national and global trends, influence the particular development of the components of the financial network. Today, the development of the regional banking infrastructure has a great impact on the economic development of the region, as other components of the financial infrastructure are developing more slowly. Historical and geographic factors especially distinguish the Western region of Ukraine from others. The influence of historical preconditions that led to the formation of banks, which are a special type of financial and credit institutions, is assessed. This forms the basis for growth in the financial services market. Banking institutions are characterized by universality among other components of the monetary infrastructure. Banking infrastructure plays an important role in the financial sector and is pervasive in all spheres of geospace in today’s globalized world. Demographic and socio-geographic factors in the regions of the Western region of Ukraine are taken into account. The impact of international experience and local government reform was assessed. The patterns of uneven development at the regional level are characterized. The unevenness of financial flows of capital and the share of investments were revealed.

The territory of the sands consists of seven hilly sand massifs and six inter-arenial flat-level geocomplexes. The relief and peculiarities of the formation of this territory are still insufficiently studied, the relief of the intra-arenial landscapes is almost completely unexplored. The objectives of this study were sys- tematics and typology of the relief forms with approaches to elucidating the factors and mechanism of formation of geomorphological formations of Oleshkivski Sands. The methods of research of the relief of the Oleshkivski Sands were based on existing experience in identification, mapping, classification, analysis of sandy landforms, deciphering their portrayal on satellite images, as well as on many years of field research by the author. The generalized and systematized analysis of the relief, illustrated with maps, tables and photo- graphic materials, allowed us to form the systematics of the microforms of the relief and the typology of the mesorelief of the Olesh- kivski Sands. The results of such studies have revealled the morphological and genetic diversity of individual landforms within the arenas and inter-arenial geocomplexes, and a total of seven arenas of the Oleshkivski Sands, and respectively the complicated history of the formation of the region. Of the arenial geocomplexes, the hilly massifs and intra-arenial depressions were considered separately. Among the hilly massifs, the dominant were found to be hilly and undulated chaotically-configured structures, at some places with the distribution of parabolic dunes and dune ridges, and also the subordinate spread of the mound massifs. The morphological and genetic diversity of inter-arenial depressions was determined, which can be considered as diagnostic objects in the formation of the Oleshkivski Sands. The analysis of the relief of the territory of the Oleshkivski Sands revealed that different factors were in operation at different time stages of its formation – fluvial (fluvioglacial), aeolian, suffusion-subsidence, thalassogenic, anthropogenic. Аt the present stage the dominant are aeolian and anthropogenic factors. Special attention was paid to parallel hilly ridges of the Kinburnska and Kelegeiska arenas, considered in the context of the diluvial (catafluvial) paradigm as a manifestation of giant ripples. The discreetly formed parallel ridges and extended hollows of the Kinburn Peninsula are presented in the context of flood-freshet events in the history of the function- ing of the Dnipro and the Southern Bug, in places where water masses flow through watershed geocomplexes. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"2 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88917216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzes the possibility of using phosphogypsum for the construction of roads. The objective was a geoecological analysis of the danger of phos-phogypsum stockpiles and a study of the possibility of using phosphogypsum in road construction to solve the problem of its accumulation in the environment. The chemical composition of phosphogypsum samples of the Sumyhimprom and Rivneazot companies was studied using the method of X-ray diffractometry. The content of heavy metals (HM) was analyzed using atomic absorption spectros-copy. An extremely high level of chromium was determined, accounting for more than 20-33 Maximum Concentration Values (MCV). The content of cuprum in the phosphogypsum samples of Rivneazot was 2 MCVs. The contents of other heavy metals did not exceed the MCVs, the synergistic effect should be taken into account. Migration of heavy metals is one of the main problems associated with phosphogypsum stockpiles. The increased acidity of phosphogypsum promotes the formation of soluble HM compounds. Depending on the solubility of toxicants, they accumulate in the ecosystem or migrate, dissolve, and enter plants. The traditional methods of storing phosphogypsum, both from an environmental and economic points of view, are less acceptable than the methods of its recycling and reuse in various sectors of the national economy. The paper theoretically substantiates that the reuse of accumulated phosphogypsum and the implementation of new technological solutions in road construction would reduce the level of technogenic loading that phos- phogypsum imposes on the environment. Based on the analysis of the content of heavy metals and the development of concentration logarithmic diagrams, mobile forms of metals were studied and the harmful effect of metals leaching from phosphogypsum was considered. We determined the positions of toxic substances in the engineering road construction – environment. We recommended dividing hydroxides and hydroxocomplexes of heavy and toxic metals into three groups according to their solubility, having the ability to migrate in acidic, neutral and alkaline environments, respectively. Strict regulations are needed to protect soil cover in areas with acidic soils. We grouped soils on which it is not recommended to use engineered road structures with phosphohypsum due to increased migration of HMs into the ecosystem: sandy; soils rich in humus components, acidic soils (sod-podzolic) or in case of existing proba- bility of an increase in soil acidity (unorganized ingress of industrial waste, acid rain, etc.); acidic soils salinized with chlorides; soils containing ammonia; soils containing sulfates. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"344 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89241105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several sulphide-polymetallic deposits in Azerbaijan, the reserves of which were approved back in the days of the USSR. Of these, the Filizchay deposit is the most unique in terms of its reserves and ore composition. The development of other deposits adjacent to the Filizchay deposit, separately, is inexpedient because of their small reserves. However, the development of sulphide-polymetallic deposits in Azerbaijan is complicated by the revealed tendency of industrial types of ores to oxidation and spontaneous combustion. In this regard, there was a need for a special study of the chemical activity of sulphide ores and the phenomena accompanying oxidative processes, taking into account the natural features of the deposits in order to obtain the initial parameters necessary for scientifically based technological solutions for their development. Sulphide ores of sulphide -polymetallic deposits of Azerbaijan significantly differ in material composition, conditions of occurrence and mining technical features of their development from the listed deposits, the issues of spontaneous combustion of which have been studied for a long time. Until now, there are no general criteria for assessing the fire hazard of sulphide ores, suitable for any deposit, since the conditions for the occurrence of underground fires at different deposits are different. It is this circumstance that makes it necessary to conduct special studies for each deposit separately. Therefore, the need for a special study of this problem on the example of the conditions of sulphide-polymetallic deposits in Azerbaijan, which are prone to oxidation and spontaneous combustion, is of great importance.

We focused on the geological routes he took when travelling along the lines of railroad construction, including Orenburg, Ural, Mariupol (Donetsk) and Katerynoslav, analyzing the conclusions on the structures of those territories, as well as perspectives of finding natural resources in them. We characterized the most important routes V.

The achievements of V. Domger as a paleontologist were ahead of his time and – despite attempts of some notable researchers to refute the Late Eocene age of the Mandrykivka layers, the first identifications of the researcher were accurate and have been convingcingly confirmed by modernday studies.

Goal: Based on the reservoir characteristics of rock samples obtained from exploration wells drilled in the area adjacent to the field, petrophysical models have been compiled, reflecting the spatial variation in porosity and permeability of oil-containing reservoirs. Objects: Consideration of the petrophysical properties of core samples taken in the study area made it possible to confirm the oil and gas potential of deep-seated reservoirs. Methods: This analyzed the values and variation of petrophysical properties by depth, age and various physical factors. The observed wide range of changes in the reservoir properties of rocks in the study area is mainly due to tectonic changes, lithological heterogeneity of the sedimentary complex, differences in the depth of bedrocks, as well as the complexity of tectonic conditions. As a result, to predict the oil and gas content in deep reservoirs of the same structures, it is advisable to use the methods of exploration geophysics, as well as the results of changes inthe reservoir characteristics of rocks, determined by petrophysical data. At the same time, it is most expedient to focus on the study of Paleogene-Cretaceous tectonics for the search for oil and gas objects using prospecting and exploration (preferably aerial-photo-space) works at the field. Results: Models made in 3D format illustrate the predicted oil and gas potential and patterns of distribution of productive horizons involved in the geological structure of oil and gas deposits, along the depths and stratigraphic units. It is shown that although the permeability of the rocks in the area is low, the porosity values are favorable for the industrial accumulation of hydro-carbons. Fractured carbonate reservoirs of the Upper Cretaceous are the most promising among the Mesozoic sediments in the OGRbetween the Kura and Gabirri rivers. Deep-seated structural uplifts complicated by large-amplitude fractures are recommended as the priority targets for further geological exploration. However, the real potential of the Eocene deposits, which are widespread in the NGR between the Kura and Gabirri rivers, remains unexplored by deep drilling. This is due, on the one hand, to the incomplete opening of the Eocene section in the structures prepared for deep drilling, structural-tectonic and lithofacies features, as well as insufficient knowledge of drilling for oil and gas, and on the other hand, poor development of promising intervals of the section. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"15 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72937764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the basis of the analysis and generalization of the leading physical-geographers’ and landscape scientists’ views the regularities of evolutionary transition of understanding the content of the landscape and complex categories from the system paradigm to the synergetic paradigm under the influence of humanistic ideas are reflected. It is stated that the landscape in a broad interpretation can be identified with the natural-territorial complex (NTC) of a certain rank, which is understood as a spatial and temporal system of geographic components, interrelated in their location and developing as a whole. The concept of territorial-production complexes (TPC) was substantiated and their typification was proposed. The factors of formation of the additional economic effect of TPC on the basis of territorial and organizational unity and mutually beneficial relations between its elements, as well as providing an integrated use and processing of raw materials and energy were determined. The key features of the concept of socio-geographical complexes (SGC), which were an important geographical tool in the search for the ways ensuring sustainable development of territories, were characterized. It has been established that the SGC concept is fundamentally different from the TPC concept by the vertical nature of the links between different types of economic activity within the system, and, in addition, by attributing to SGC not only material but also spiritual components of human activity. The character and qualities of the synergistic effect of space are analyzed. The synergistic properties of landscapes and complexes are described and their various categories within the concept of spatial synergy arising in those points of space, where the traditional mechanisms of human existence do not exhaust their potential. It is emphasized that based on the use of the synergistic effect mankind in the future will be able to develop effective mechanisms of management and territorial organization, which will open up new directions for the implementation of previously hidden reserves and properties of space. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"17 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75014021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
