This paper focuses on the comparison of Ni and Pb concentrations in air and soil pollution in the Zagreb area. Due to the very limited amount of publicly available data from soil analysis samples, 2016 and 2019 were chosen as the best possible indicators of related changes in metal concentrations in soil and air. Methods. Testing the normality of Ni and Pb concentrations in the total deposited matter (TDM) confirmed the feasibility of using two parametric statistical tools – the Pearson correlation coefficient and the t-test. The Inverse Distance Weighting (IDW) interpolation method was selected as the best approach for a small number of measurements. Findings. The insufficient amount of data is the main shortcoming for urban health policy in a large area like Zagreb. The small number of air measurement stations and especially soil sampling sites cannot lead to any reliable conclusions about urban pollutants, their activity over time and direct links to soil toxic degradation based on statistical or geological methods and analyses. However, there is no doubt that urban pollution sources fill the soil with accumulated toxic elements such as Ni and Pb, especially in suburban areas located along the paths of the dominant wind directions. Originality. This is an original research that for the first time statistically analyzes and maps publicly available air and soil pollution data for the period 2016-2019. Practical implications. This research is a necessary step in determining the future planning of air and soil measurement stations in the Zagreb urban area.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46245380","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}

In the electronics industry, stibium (Sb) is an important element used in the development of silicon-based devices. The metallogenic district of Guelma, known for its polymetallic antimony mineralization, is not currently exploited. The research purpose is to characterize the minerals and gang formations of antimony elements required as dopants during the growth of monocrystalline silicon. Methods. The research methods include detailed geological mapping and sampling, XRD mineralogical identification, XRF geo-chemical analysis, and atomic absorption spectrophotometry. Findings. The results obtained prove that Sb mineralization is the youngest in the North-East of Algeria, since it is hosted in the dolomitized lacustrine limestone of the Mio-Plio-Quaternary. The mineralization has been deposited by the replacement and filling open spaces. A supergene alteration of the Nadorite mineral has led to the antimony sulfides appearance. Originality. Unique mineral species of the world have been identified: Nadorite in Jebel Nador, Flajolotite in Jebel Heimel, valentinite in Jebel Senza, senarmontite in Jebel Hammimat, and cervantite near Aïn Kerma. The Ham-man N’Baïls deposits still contain significant reserves of Zn, Sb, and Pb. Practical implications. With the help of this study, we have answered questions related to the origin of the mineralizing fluids responsible for the formation of deposits. In addition to the epigenetic nature of the mineralization with the formation of unique and rare minerals throughout the world, the presence of gold in this region has been proven by chemical analysis.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47202923","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}

{"title":"Effect of ore heterogeneity on the ball mill wear rate during a grinding process at gold mines of Saudi Arabia (KSA)","authors":"G. S. Abdelhaffez, Haitham M. Ahmed, H. Saleem","doi":"10.33271/mining17.02.071","DOIUrl":"https://doi.org/10.33271/mining17.02.071","url":null,"abstract":"Purpose. The current research aims to study the effect of gold ore grinding on the wear rate of grinding balls. Methods. Six boulder rock samples were selected from some KSA mines; five core samples were taken from each of them to identify the mechanical properties (compressive strength, Young’s modulus, and Poisson’s ratio). These mechanical properties were applied to identify the hardness class of all 30 core samples. Five samples with different mechanical properties from the same boulder sample were milled to study the effect of the compressive strength difference and grinding time on wear rate. Then, six samples were taken from different regions with similar mechanical properties but different petrographic characteristics. They were also milled under the same grinding conditions to study the effect of the microscopic mineral composition on the wear rate. Findings. The results showed that the wear rate increased with the improving mechanical properties and with the increa-sing grinding time. On the other hand, the results based on different microscopic descriptions of the six samples showed that despite similar mechanical properties, the wear rates differed. Petrographic characteristics confirmed the presence of quartz in most of the samples as an associated mineral; it is likely that it has the greatest effect on the grinding ball wear. Originality. The paper proposes a method for investigating ore heterogeneity, which has a major impact on the wear rate during a grinding process, as well as on the reducing costs and improving efficiency of grinding media. Practical implications. The research emphasizes the importance of investigating variables (e.g. ore heterogeneity) other than ball size, grinding medium composition, and wet or dry grinding that have a substantial impact on grinding efficiency. The findings could be applied in feasibility studies to calculate and evaluate grinding costs versus grinding efficiency.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47415771","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}

The research purpose is to study the effectiveness of artificial maintenance of the mined-out space based on the use of cable bolts to reduce the dilution coefficient when mining low-thickness ore bodies. Methods. Geotechnical mapping of the rock mass according to the Q, RMR, RQD and GSI rating classifications is conducted, as well as a linear survey of the fracture system in the hanging wall and footwall rocks is performed using a rock compass and the GEO ID application. Numerical analysis by the limit equilibrium method in the Unwedge software package is applied to determine the safety factor of a mass divided by fractures into wedges. Using a Schmidt test hammer, the uniaxial compressive strength of the mass rocks has been determined. The full-scale studies have been conducted using cable support in the conditions of the Akbakai deposit. Findings. It has been revealed that the footwall rocks are in a stable state, while the safety factor of the hanging wall rocks is 0.98, which requires artificial maintenance using cable bolts. The cable support parameters are calculated taking into account nonuniform distribution of horizontal and vertical stresses in the rock mass. It has been determined that when strengthening the hanging wall with cable bolts in inclined veins with a dip angle of up to 40º, the average ore dilution is 66.1%, and that of previously mined without fastening is 68.7%. In similar experiments in steep-dipping veins with a dip angle of more than 60º, dilution decreases from 62.8 to 48.7%. Originality. It has been revealed that in the conditions of the Akbakai deposit, cable fastening of the hanging wall rocks is effective at an ore deposit dip angle of more than 60º, at which the mined ore dilution coefficient decreases. Practical implications. The research results can be used to increase the stability of hanging wall rocks when mining low-thickness ore bodies with a sublevel caving system.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48313512","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}

Zharaspaev, Rustem Nurkasyn, Bolegen Zhakupov","doi":"10.33271/mining17.01.129","DOIUrl":"https://doi.org/10.33271/mining17.01.129","url":null,"abstract":"Purpose. To ensure the roof span stability in terms of room-and-pillar system of mining taking into consideration the calculations, modelling, and statistic analysis of factual rock falls from the roof. Methods. Analysis of inelastic deformations to define overall displacement of a thin-layer roof of the chamber being 9 m wide was performed with the help of software complex RS2. To estimate the effect of chamber spans on the roof stability, a problem was considered in two variants where chamber width was 8 and then 7 m. The results were analyzed in terms of strength factor of the interchamber pillars. Statistic analysis of the roof stability loss for the chambers was carried out according to the results of monitoring of a state of the worked-out space in the context of the Zhaman-Aibat deposit. The obtained data were compared in terms of chamber roof spans being 9-7 m. Findings. The performed studies make it possible to state that the reduction of chamber spans down to 7 m decreases the roof deflection up to 2 cm and ensures stability of both chamber roof and worked-out space by 13 times; in its turn, that results in safe conditions while stoping. Optimal parameters of the roof span stability for chambers and safe mining conditions were substantiated basing on computer modelling and statistic analysis of the results of geotechnical monitoring of a state of worked-out space at the Zhaman-Aibat deposit. Originality. The regularity of changes in the safety factor of the peripheral part of a chamber was substantiated depending on the chamber width (7, 8, and 9 m) and considering the distance from the contoured chamber (m). Reduction of the chamber span by 1 m (from 9 to 8 m) reduces roof deflection by 2 times (up to 5 cm); moreover, breaking depth in the roof experiences considerable reduction – up to 1.75 m. Reduction of the chamber span by 1 m more (from 8 to 7 m) reduces the roof deflection up to 2 cm; breaking depth in the roof decreases considerably as well – up to 1.33 m. Practical implications. The proposed variant of chamber span reduction can decrease significantly the total area of rock falls and ensure stability of the worked-out space of the Zhomart mine where roof stability is the weakest element on the mining system. The obtained results can be the basis for the development of methodological recommendations to calculate mining parameters at the Zhaman-Aibat deposit as well as at other deposits with medium roof stability.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45650713","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}

Matkivskyi","doi":"10.33271/mining17.01.101","DOIUrl":"https://doi.org/10.33271/mining17.01.101","url":null,"abstract":"Purpose. The research purpose is to increase the efficiency of development of gas condensate fields with a high condensate yield in the reservoir gas and to develop optimal ways of increasing their hydrocarbon recovery. Methods. The effectiveness of the implementation of reservoir pressure maintenance technologies using dry gas for the development of gas condensate fields with a high condensate yield in the reservoir gas is studied on the basis of a heterogeneous 3D model using the Schlumberger Eclipse and Petrel software packages. The technological indicators of the development of gas-condensate reservoir are studied for different pressure values at the beginning of the dry gas injection. Calculations were made for pressures at the beginning of injection at the level of: 1.0 Рinit; 0.8 Рinit; 0.6 Рinit; 0.4 Рinit; 0.2 Рinit. Findings. It has been determined that when the dry gas is injected into a gas-condensate reservoir, reservoir pressure is maintained at a significantly higher level than it is in the case of depletion. This ensures stable operation of production wells over a longer period of the reservoir development. According to the research results, it should be noted that in the case of implementation of the reservoir pressure maintenance technology, a part of the precipitated condensate is transferred to the gas phase, which makes it necessary to extract it together with the reservoir gas. Based on the modeling results, the ultimate condensate recovery factor have been calculated. The calculation results indicate that in the case of the cycling process implementation, the ultimate condensate recovery factor of the gas-condensate reservoir increases by 7.26% compared to depletion development. Originality. Based on the calculation data analysis, the optimal pressure value at the beginning of dry gas injection into a gas-condensate reservoir has been determined, which is 0.842 Рinit. Practical implications. The use of the conducted research results will optimize the development system of gas-condensate fields with high initial condensate yield in the reservoir gas and increase the efficiency of development the explored hydrocarbon reserves in the conditions of a significant shortage of hydrocarbon raw materials in Ukraine. The conducted research results indicate the high technological efficiency of the reservoir pressure maintenance technology using dry gas.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":"29 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69439022","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}

The neritic aquifer that extends between Hammam Bradaa and El Fedjoudj, despite its faulted and in places karstified structure, due toits capacity and lateral extension represent a strategic resource for the region. Its waters are used for drinking water supply in the neighboring towns: Heliopolis, Guelaat Bousbaa, Nechmaya and El Fedjoudj, as well as in part of the Annaba wilaya. These neritic limestones outcrop at Djebel Debagh and Bouzitoune. Methods. In order to better study the potential of this aquifer, it is essential to identify its geometry and structure by analyzing the geological data, mechanical drilling data and geophysical data analysis through an electrical survey campaign. Findings. The main results indicate that the study area has identified two important aquifer formations: a formation in the Mio-Plio-Quaternary alluvium consisting of clays, marls, gravel and sand; the second is a deep carbonate aquifer composed of fissured and karstified neritic limestone of the Cretaceous age of variable depth ranging within 50 and 350 m. Originality. The originality of the study is in the fact that the studied area is characterized by the presence of thick, fractured and karstified carbonate formations, which are intensively tectonized and have significant aquifer potential. Practical implications. The correlation of geological data with geophysical data made it possible to conclude that the stu-died area is a sedimentary basin bounded by faults predominantly oriented to the south-west and north-east, forming a highly fractured unit consisting of horsts and grabens. The significant water potential reservoir is formed essentially by carbonate geological formations, highly fractured with the presence of karst forms represented by resistant horizons.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48671653","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}

The samples have been taken from Donbas coal seams varying in their ranks (i.e. carbonization degree). Findings. It has been identified that in the context of outburst hazardous zones, the ratio between integral intensity of spectral RS bands D and G, K = I(D)/I(G) shows abnormal dependence upon the nominal amount of volatile compounds connected with the impact by iron impurities.

The research purpose is to develop a mathematical model of a pressureless flow in a channel with the occurrence in some areas of overflow layer through the wall. Using this model, it is possible to calculate the overflow layer height and length, as well as the change in flow rate in the channel due to the withdrawal of part of the fluid as a result of the overflow. Methods. The research uses a comprehensive multi-stage analytical approach. Firstly, in order to develop a mathematical model for a pressureless flow in the channel with the occurrence in some areas of overflow layer through the wall, this research analytically determines the dependence of the flow rate through the channel wall based on formulas for calculating the weir discharge coefficient. At the second stage, a mathematical model of a hydraulic mixture pressureless flow in a rectangular channel with an overflow through the wall is developed to determine the parameters and flow regimes of the stream. Findings. The dependences of the dimensionless height of the overflow through the channel wall and the effective critical flow depth on the dimensionless current channel length have been obtained for various values of the acting force parameters and the process parameter of the fluid overflow through the channel wall. This made it possible to study the dynamics of changes in these values along the channel for various values of the specified parameters, and to assess the degree of influence of the relevant factors on the characteristics of the pressureless flow along the channel and the process of fluid overflow through wall. Originality. For the first time, the model of the pressureless flow in the channel is generalized for the case of occurrence in some areas of overflow layer through the wall, when the length and height of the overflow layer are not determined by a hole in the side surface, but are controlled by a decrease in the corresponding flow rate. For the first time, this model makes it possible to calculate the height and length of the overflow layer and the change in the flow rate in the channel due to the withdrawal of part of the fluid as a result of the overflow in cases of overflowing condition of the channel with the stream under unstable and non-calculated flow regimes.
