The objective of this study was to assess the risk of potentially toxic elements in soil samples surrounding ferronickel mines in the Golesh massif, Republic of Kosovo. Methods. In total, 14 potentially toxic elements (Al, As, Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Ni, Pb, V and Zn) were investigated. Basic statistics, Pearson correlation, Principal Component Analysis (PCA), and Pollution indices (CF, PLI, Igeo, and EF) were used to explain better the data on metal concentrations in the soil samples. Findings. Five groups of elements were identified by PCA, based on their geogenic or anthropogenic origin. The contamination factor for nickel ranged from 6.9 to 166, with a mean value of 65.17. Cobalt and magnesium also had high mean values of contamination factor: 10.38 and 9.76, respectively. The PLIsite for 14 locations were highly polluted with metals (PLI > 4), and the PLIzone of the whole territory investigated was 3.5. The mean value of Igeo for nickel was 5.44, for cobalt (2.79) and for magnesium (2.7). The mean value of enrichment factor (EF) for nickel, cobalt and magnesium was 233.7, 35.26 and 19.16, respectively. Originality.Soil samples were collected from 30 different locations in accordance with the soil sampling protocol. The samples were sent for further analysis at the ACME, Ltd. laboratory in Vancouver, Canada. The soil samples were digested with aqua regia, and the content of 14 chemical elements was determined using inductively coupled plasma-mass spectrometry (ICP-MS). Practical implications. Based on statistical analysis and pollution indices, we concluded that most soil samples were highly polluted with Ni, Co, and Mg, resulting from the ferronickel and magnesite mines located in the region under investigation.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":"19 4","pages":"139-146"},"PeriodicalIF":0.0,"publicationDate":"2025-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"http://mining.in.ua/articles/volume19_4/14.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to investigate the characteristics of blast-induced vibrations in Algeria’s Rouina open-pit mine and their potential impact on nearby infrastructure, specifically the Ouled Mellouk Dam, located downstream. The research seeks to understand the propagation patterns of these vibrations and assess their environmental and structural consequences, with a focus on risk mitigation strategies for infrastructure protection. Methods. The research was carried out through experimental explosion tests at Rouina mine. Advanced tools such as ETNA-type accelerographs and seismographs with highly sensitive triaxial LE-3Dlite sensors and a K2 digitizer were utilized to measure the induced vibrations. Various parameters related to the fragmentation process were adjusted to analyze their effect on vibration characteristics. The damping coefficient of the rock mass was calculated using Chapot’s law, and potential impacts on water discharge were also examined. Findings. The results indicate that the blast-induced vibrations have significant effects on vibration propagation, posing potential risks to nearby infrastructure. The research has also determined the rock mass’s damping coefficient, which serves to explain the behavior of vibration damping. The findings show that the implementation of optimized blasting plans can effectively control vibration levels and mitigate risks to structures such as the Ouled Mellouk Dam. Originality. This research provides new insights into the behavior of blast-induced vibrations in open-pit mining, especially when in proximity to critical infrastructure. The innovative use of advanced instrumentation and the application of Chapot’s law for vibration analysis emphasize the originality of the research. Practical implications.

The research is aimed at increasing the useful component content in a pregnant solution during in-situ leaching (ISL) using a solid oxidizer and increasing the ferric iron concentration in the leaching solution based on laboratory research. Methods. Laboratory research is performed on a specially developed model electrolyzer for obtaining comparative data on divalent iron oxidation to trivalent iron and the change in the useful component content in a pregnant solution. Firstly, tests are conducted with a basic leaching solution, then on the oxidation of the leaching solution with a solid oxidizer in the form of a lead dioxide plate. Tests are conducted by changing sulphuric acid concentration within 5-50 g/l, amount of divalent iron ions in the solution from 0.5 up to 4.0 g, lead dioxide plate surface area from 19 to 76 cm2. The leaching time is up to 10 hours. Findings. The results of laboratory research on determining the oxidation degree of divalent iron ions and change in the oxidation-reduction potential (ORP) depending on the sulphuric acid concentration and on the initial concentration of divalent iron ions in the initial solution are presented. With a change in the sulphuric acid concentration from 5 to 50 g/l, the oxidation value of divalent iron ions increases from 26.5 to 96.5%, and with an increase in the initial solution concentration of divalent iron, the oxidation degree of divalent iron naturally decreases from 95.2 to 58.8%. In the initial leaching solution, the divalent solution concentration is 312 mg/l, and that of the trivalent solution is 288 mg/l. After oxidation with a solid oxidizer, the divalent and trivalent iron concentrations are 56 and 392 mg/l, respectively. In the course of further laboratory research using core materials from a uranium deposit, it has been revealed that when leaching with a basic solution, the uranium content in the pregnant solution is 19.36 mg/l, and when leaching with a solution after oxidation with a solid oxidizer, it is 27.9 mg/l, which is by 8.54 mg/l more. Originality. New dependences have been determined of the oxidation degree of divalent iron ions to trivalent one on the sulphuric acid concentration and on the initial concentration of divalent iron ions, as well as the useful component content in the pregnant solution on the leaching time when using a solid oxidizer. Practical implications. Using of a solid oxidizer, it is possible to increase the trivalent iron concentration in the leaching solution and the useful component content in the pregnant solution compared with the basic technology, thereby reducing the time of mining uranium reserves. Proposed technology is environmentally friendly, with low capital costs.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139140075","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 aims to investigate the impact of discontinuity characteristics, including dip direction, dip and joint spacing, on the size distribution of blasted fragments in mines and quarries. The accuracy of blasting results is essential for efficient operations, and understanding these factors can enhance blast fragmentation outcomes. Methods. We conducted our research at the Jebel Bouzegza C01 aggregate quarry, analyzing eight blast benches. To determine fragment sizes, we employed image processing tools to calculate P50, P80, and Pmax sizes. Additionally, we used the Kuz Ram model to predict the average size (X50) and the percentage of oversize fragments (Pmax). The determination coefficient (R²) is calculated for both methods to assess their correlations with dip direction. Findings. Our analysis revealed significant findings related to the impact of discontinuity characteristics on fragment size distribution. The dip direction exhibits the strongest correlation of Pmax size when using Split Desktop and X50, as well as Pmax% with the Kuz Ram model. Joint spacing also plays a role in influencing blast fragmentation outcomes, although its effect depends on the infill materials. Originality. This research contributes to the understanding of factors affecting blast fragmentation outcomes. The research focuses on dip direction, dip and joint spacing characteristics, and adds to existing knowledge in this field. Practical implications. The findings of this research have practical implications for mines and quarries, offering valuable guidance for site investigations and optimization of blasting practices. By assessing properties such as dip direction and joint spacing, blasting operations can be enhanced to achieve more efficient and accurate results.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139138610","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 importance of mineralogical characterization for complex ore deposits is continuously increasing due to the increasing demand for minerals worldwide. The proper mineral characterization needs to be carried out for selecting appropriate processing technology for the beneficiation of complex ore in order to efficiently obtain ore concentrate according to the market demand. The purpose of this study is to carry out a detail mineral characterization of the complex lead-antimony ore deposit of Chitral, Pakistan, necessary for selecting the most appropriate processing technology and designing a mineral processing plant.

Mining-induced land subsidence is a significant concern in areas with extensive underground mining activities. Therefore, the prediction of land subsidence is crucial for effective land management and infrastructure planning. This research applies an artificial neural network (ANN) to predict land subsidence over the Mong Duong underground coal mine in Quang Ninh, Vietnam Methods. In the ANN model proposed in this research, four features are used as the model inputs to predict land subsi-dence, i.e., model outputs. These features include the positions of ground points in the direction of the trough main cross-section, the distance from the chamber (goaf) center to the ground monitoring points, the accumulated exploitation volume of extraction space, and the measured/recorded time. The entire dataset of 12 measured epochs, covering 22 months with a 2-month repetition time period, is divided into the training set for the first 9 measured epochs and the test set for the last 3 measured epochs. k-fold cross-validation is first applied to the training set to determine the best model hyperparameters, which are then adopted to predict land subsidence in the test set. Findings. The best model hyperparameters are found to be 5 hidden layers, 64 hidden nodes and 240 iterated epochs. Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) of the predicted land subsidence depend on the time separated between the last measured epoch and the predicted epoch. Within 2 months from the last measurements, RMSE and MAE are at 22 and 13 mm for Epoch 10, which increase to 31 and 20 mm for Epoch 11 (4 months from the last measurement) and 37 and 24 mm for Epoch 12 (6 months from the last measurement).

Methods. Geomechanical stability of the protective structure has been assessed relying upon the analysis of geological-hydrogeological, engineering-geological, and geotechnical conditions of the certain tailing pond area using a deformation elastic-plastic model of a medium implemented on the basis of finite-element method. For the purpose, the dam slopes have been detalized taking into consideration their geometry as well as changes in vertical section of rock material characteristics in accordance with the earlier geophysical studies; exploration drilling; and engineering-geological surveys. Findings. Stability coefficients of protective tailing pond dam have been identified within the typical areas of a hydraulic structure; it provides high reliability and representativeness of the whole structure health in time as well as under various conditions of the industrial waste water saturation. It has been defined that the stability coefficients varies from ks = 1.372 to 4.758. Comparison of the indicators between 2022 and 2016 demonstrates a tendency of the slope stability coefficient decrease due to water saturation and groundwater level rise. Nevertheless, design characteristics of the structure make it possible to ensure satisfactory a stability coefficient along the whole dam length being 1.13 times higher than the standard one (i.e. ks = 1.250). Originality. The dependence of the tailing pond protective dam stability upon a water supply degree at the forecasted groundwater level rise at the expense of atmospheric and melt water ingress to the tailing pond has been defined. The danger of complete radioactive waste water saturation is a significant reduction in the stability coefficient of the protective structure, which can be supported by predictive modelling data. If strength parameters of a dam material decline for the most critical area then the strength coefficient decreases starting from 1.532 in terms of the current groundwater level down to 1.372 as for the forecasted dam water supply. The figure is more than 10% of its initial stability. Practical implications. The obtained results substantiate the necessity; moreover, they are of practical value while improving hydrological, hydrogeological, and geotechnical monitoring of the analyzed tailing pond to ensure its radiation safety under different conditions of further behaviour during closure, recultivation, or rehabilitation.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" 27","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139137867","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}
