The research explores the possibility of increasing the fertile properties of agricultural soils of loamy type by adding burnt-out dump mass from coal enterprises. Methods. Laboratory research on parameters of penetration and retention capacity of sorbed and meniscal water for diffe-rent burnt-out rock fractions. The burnt-out rock was sampled from the mine No. 5/6 waste rock dump in the city of Myrnohrad, Donetsk Oblast, and divided into four fractions from 0.63 to 10 mm. The water penetration coefficient of the soil with the added dump mass is measured by the velocity of water seepage into the test samples. The ability of rock additives to retain film-sorbed and capillary water is assessed by comparing the weight of dry and moistened samples of crushed dump mass. Findings. The velocity parameters of water penetration into samples of loamy mixtures with burnt-out dump mass with fractions ranging from 10 to 0.63 mm in size have been determined. It has been found that an increase in the percentage of burnt-out rock in the mixture leads to an increase in the water penetration velocity from 1.2 ml/cm2·min with a rock content of 30% to 30.66 ml/cm2·min with a rock content of 70%. The highest penetration coefficients are achieved when adding rock with a small fractional composition of 0.63-3 mm, since an increase in grain size leads to a reduction in the coefficient by se-veral times. It has been determined that with an increase in the size of the rock fractions in a loamy mixture, the retention capacity of sorbed and pore water suitable for plant nutrition decreases by approximately 40%. Originality. For the first time, the parameters of penetration coefficients, as well as the accumulation of sorbed and meniscal water for mine waste in the Selidovo-Pokrovskyi district of Donbas, have been determined. Practical implications. The results obtained can be used to improve the physical properties of agricultural soils of loamy type by increasing their water retention capacity.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" 96","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139139305","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 paper aims to assess the distribution of uranium and thorium ore grade distribution to produce a uranium potential map and estimate of the uranium ore reserves in the Gattar-V area, Eastern Desert, Egypt. Methods. Multidisciplinary approach is applied to determine the equivalent uranium mineralization in the Gattar-V area. It includes geological (petrographical, mineralogical and geochemical) and geostatistical (kriging analysis and variogram models) methods. Findings. Geological studies show that the U-mineralization located along or near the contact between younger granites and Hammamat sediments exhibits episyenitization and bleaching alteration, respectively. Geochemical studies indicate a strong relationship between U-mineralization and Chemical Alteration Index (CIA), alteration features, and associated hydrothermal solution mineralization. The geostatistical method is used to study the behavior and distribution of U and Th in both younger granites and Hammamat sediments. The Total Gamma, eU, and eTh values are used in kriging analysis and variogram models to determine their spatial dependence and perform a spatial interpolation of sparse measurements and deposition level map. Originality. The use of a multidisciplinary method combining petrographical, mineralogical and geochemical investigations with geostatistical analysis allowed for a quantitative evaluation of the spatial location of geological objects such as uranium mineralization in the area. Practical implications. Variogram models and kriging analysis can also be used to assess the lithological composition of rocks and mineralogical phases, and they also provide a clear vision of the elements distributed in the ore, which is very useful during the planning and production stages.","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":"139141484","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}

A binary mixture of a ceramic body was studied, incorporating overburden from a coal mine site in Bontang, East Kalimantan, Indonesia. This overburden material has been tested for the manufacture of stone-ceramic body. Methods. The initial characterization of overburden materials includes testing the chemical composition by XRF analysis and mineral content by XRD analysis on raw materials and overburden exposed to high temperature. The composition of ceramic specimens is a mixture of 85% overburden material and 15% fine sand. Firing temperatures in the range of 900-1100°C were applied to the ceramic body specimen. Then, ceramic properties, such as physical color, plasticity, shrinkage, water absorption and density were analyzed. Findings. The results show that the ceramic specimen experiences densification when exposed to high temperature in this range, which in turn contributes to low water absorption and high flexural strength. This ultimately results in low water absorption below 1.0% at 1100°C, which is favorable for stoneware type of ceramics. The mechanical properties of specimen at 1000°C is in accordance with stoneware body standard. In addition to this, it is believed to be more energy efficient, since the low firing temperature is sufficient to achieve the stoneware specification. Originality. The binary clay-based ceramic have been tested using coal mine overburden and river sand with a high Fe2O3 content. Together with the presence of alkali oxides and calcium in the raw materials, this can potentially reduce the use of fluxing agent. A comprehensive study has been conducted on the characteristics, firing effect and application of stoneware. Practical implications. Some ceramic prototypes from this result were also made using a rotary technique and heated in this temperature range. Since overburden is generally considered to be backfill material, the selective clay material application for ceramics can provide the potential to stimulate local product innovation by utilizing easily available overburden materials.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":" 10","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141547","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 is aimed to identify, investigate and study the parameters and characteristics of the “quarry cavities – backfill material” systems on the territory of Ukraine using new comprehensive methodological tools that form the basis for the development of effective methods for restoring the earth’s surface with an emphasis on industrial and construction use. Methods. An integrated approach is used, which includes: analysis of the spatial location of industrial waste heaps on the territory of Ukraine as potential backfill materials and resulting quarry cavities that are not subject to complete earth’s surface restoration, as well as determination of the volumes of resulting cavities and backfill materials. Based on a set of factors, the “quarry cavities – backfill material” systems have been ranked according to priority. Tools used are: information data from the State Informational Geological Fund of Ukraine, registers of industrial waste accumulation sites in region, the Google Earth satellite program, an online topographic map (OpenStreetMap) and Blender program for constructing 3D models. Findings. A new concept and theoretical representation of “quarry cavities – backfill material” has been formulated. The characteristics of a number of important conditions for the harmonious existence and effective implementation of promising “quarry cavities – backfill material” systems are provided. A new information-analytical map of the spatial location of potential backfill materials and resulting quarry cavities has been created. Thirteen promising systems and their parameters have been identified, within which it is appropriate to consider backfill technologies for the complete earth’s surface restoration.

The research purpose is to study the physical-chemical properties of ash and slag waste generated during the coal combustion at the Ekibastuz field in Kazakhstan, to determine the possibility of using waste as a secondary resource to reduce the negative human impact on the environment. Methods. The research uses the methods of X-ray phase and differential thermal analysis, as well as chemical analysis. The X-ray phase analysis makes it possible to determine the phase composition and structure of ash and slag wastes, while differential thermal analysis is used to study their behavior with temperature changes. A chemical analysis is performed to determine the composition of ash and slag. Findings. The chemical and granulometric composition of ash and slag waste from the Ekibastuz field coal combustion has been determined. Analysis of the ash chemical composition showed that its main components are silicon and aluminum oxides, as well as a significant amount of iron oxide. The results obtained confirm the possibility of using ash and slag waste as a secondary raw material to reduce the negative impact on the environment. Originality. It has been revealed that the thermal conductivity, ultimate strength and water-absorption of ceramic brick samples depend on the amount of ash added and the firing temperature. The possibility of obtaining building materials with minimum cement content has also been substantiated, which is a new and promising approach, given the high cost of cement as the main building material. Practical implications. The practical value of the research is in solving environmental problems associated with the use of ash and slag waste. Using these wastes as a secondary raw material, it is possible to reduce the anthropogenic burden on the environment, as well as the volume of ash dumps. In addition, vacant land previously occupied by ash and slag mixtures can be used for economic purposes.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136337365","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 has applied a technique of well hydraulic fracturing to study parameters of the initial stress field within the deposit. For the purpose, two metering points in two measuring (horizontal and vertical) wells were used. Hydraulic fracturing has been tested at each installation location. Findings. The in-situ measurement results have helped obtain quantitative parameters of stress-strain state of the rock mass.

Current research focuses on studying experimentally various parameters affecting the particle size produced in a vibrating jaw crusher developed and implemented at Al-Balqa Applied University. The main purpose is to find the optimal conditions at which the jaw crusher under study works. Methods. The jaw crusher angle and rotating mass type are considered to study all particle sizes and reduction ratios obtained for three different motor operation speeds: 1500, 2000, and 2500 rpm. Coarse aggregate weighing 900 g with 26 mm particle size is fed into the jaw crusher, which produces several particle sizes (19, 12.5, 9.5, 4.75, and less than 4.75 mm). Furthermore, the mass of the particles is measured and the particle size reduction is calculated. Findings. It has been found that the jaw crusher angle, rotating mass type, and the motor operation speed play an important role in both reducing the amount of mass and reducing the size of each particle produced. In addition, it has been determined that operation at a speed of 2000 rpm provides a significant change in both mass and size reduction of each particle size considered. Originality. The originality of this research lies in its experimental investigation of the effects of various parameters on particle size reduction in a vibrating jaw crusher, as well as in the introduction of a new design that uses one motor to drive two plates operating at different speeds and in opposite directions. Practical implications. The findings can be used to optimize the design and operation of jaw crushers in various industries, including metallurgical, quarry, and mining industries, where these crushers are widely used.

M Ali","doi":"10.33271/mining17.03.001","DOIUrl":"https://doi.org/10.33271/mining17.03.001","url":null,"abstract":"Purpose. The research aims to investigate how the load influences the ultimate compressive strength of rocks at failure. It uses both a uniaxial compression test, which involves incremental displacements, and a triaxial compression test, which applies varying confining stresses while maintaining a constant axial compression stress and incrementally increasing the displacement. Methods. To conduct the investigation, the researchers used RS2D, a rock-soil software, to examine the impact of different incremental displacements and confining stresses on the strength properties of various rock samples. The numerical analysis includes Fayum argillaceous sand, Sinai coal, Aswan granite, Assiut limestone, and Red-Sea phosphate. Findings. The research findings indicate that the ultimate compressive strength of rocks at failure is achieved with minor incremental displacements. Conversely, an increase in the confining stress leads to higher ultimate tensile strength, deviatoric stresses, and volumetric strain. However, the stress factor decreases in relation to the axial strain percentage. Originality. The simulator adopts Mohr-Coulomb failure criterion, presents and discusses the results in terms of stress-strain (σ-ε) curves, stress ratio (σ1/σ3), deviatoric stresses (σ1-σ3) and volumetric strain with respect to the percentage of axial strain. Practical implications. Using numerical modeling analysis, it becomes possible to reproduce the rock failure mechanisms observed in uniaxial and triaxial compression tests. This methodology has the potential to reduce the need for extensive experimental testing when assessing the tensile strength of rocks under different loads. As a result, both time and costs can be minimized.","PeriodicalId":43896,"journal":{"name":"Mining of Mineral Deposits","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136336299","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}

Natural fractured reservoirs are a special category of reservoirs due to the effects of porosity and permeability. Optimizing the exploitation of hydrocarbon reserves in this type of reservoir requires a specific study compared to other conventional reservoirs. Methods. We have focused on the quantitative analysis of seismic traces for the purpose of an automatic seismic facies recognition strategy. The study area, the Amguid-Messaoud Basin, is formed by a series of horsts and grabens bounded by submeridional “North-East and South-West” faults, as well as perpendicular “North-West and South-East” faults with-out outcrops of fractures, which have a great influence on reservoir fracturing. A set of statistical data analysis methods, such as principal component analysis, discriminant factor analysis, and automatic classification, have been tested on real data from geophysical seismic data interpretation, in particular the stratigraphic interpretation.

Methods. The analytical research involved a theory of random processes adapted to the real conditions. For the purpose, results of experimental measurements have been applied obtained under the conditions of active iron ore enterprises using underground procedures of the raw materials mining. Methods of random functions (i.e. elements of correlation theory) have helped identify the basic input and output parameters characterizing rather completely electric supply consumption as a stochastic process to develop a control algorithm for the process. Findings. A mathematical model of an electric supply/consumption complex as a stochastic process has been developed to assess its features as well as its levels of influence on the economic operational indices of electric power system of under-ground mining enterprises. Formation of the algorithm to control distribution of electric power flows among consumers of the analyzed types of iron ore enterprises took into consideration stochastic nature of the mentioned complex activity. Originality. The procedure of electric supply/consumption by underground iron ore enterprises has been analyzed in the format of process of a stochastic process of their operation. For the first time, the synthesized mathematical model has been built; both average and disperse stochastic characteristics of electric consumption capacity have been identified; average period of electric energy consumption as a stationary random function during the specified time has been determined; and average number of electric consumption peaks for the interval has been defined as well as average duration of their surges. Analysis of the electric supply/consumption process as a stochastic process has helped solve a problem of the peak influence on the modes of electric energy consumption by receivers of the enterprises, i.e. the random function crossing the specified electric consumption level. Practical implications. According to the available computing formats, a calculation procedure of the operation parameters of electric supply/consumption is of insufficient accuracy since average values are applied and stochastic nature of the process is ignored, which is typical for the analyzed mining enterprises. The abovementioned restricts the possibility to develop adequate system to control the electric power process in terms of the types of mining enterprises and specificity of their operational technology.
