  • Ore and Backfill Dilution in Underground Hard Rock Mining

    • Free pre-print version: Loading...

      Abstract: The ore dilution is generally defined as the degradation of economical and valuable ore with the addition of the unwanted host rock, failed backfilled material and or ore material considered below the cut-off the grade. The importance of ore dilution on the profitability of a mining operation is very well known and also well documented, since, it adds to the cost of mining, hauling, transportation, milling and processing etc. It also differs from one mining operation to another, the ore type being extracted, the type of the host rock present and type of mining method applied, type of backfilling method and material used, including other mining parameters. The ore dilution is generally expected at all stages of mining operation including the very first step of stoping in the case of hard rock mining, where, the low-grade ore is extracted un-intentionally or intentionally to insure the safe mining environment including excavation stability and or towards the easy movement of men and machineries. It is well known that the numerous parameters including mining and rock mechanics influence the occurrence of ore dilution in the case of underground hard rock mining. Herewith, through review study, the problem of ore dilution, various factors affecting dilution, its measurement and possible control measures is discussed.

  • Laboratory Research of Slope Stability under Impacts

    • Free pre-print version: Loading...

      Abstract: The authors discuss the lab-scale studies into sub-horizontal effect of a low-frequency seismic wave on a slope. Acceleration transducers enabled tracing relative slope sliding even in case of invisible straining. It is found that if the maximum acceleration in the momentum is below a certain value governed by the soil strength, the slope keeps stable even at high displacement velocities. A single impact at high acceleration but low mass velocity is also incapable to initiate landslide. However, in this case, residual strains arise, accumulate and can make the slope unstable. Under multiple impacts, the critical parameters are markedly lower as compared with the single impact. This is particularly true for steep slopes having small stability factors. The parameters of vibrations generated by different-magnitude earthquakes which initiate slope failures in the form of landslides are analyzed.

  • Brazilian Tensile Strength Testing

    • Free pre-print version: Loading...

      Abstract: The paper discusses the direct and Brazilian tensile strength testing data in terms of the mechanical properties of rocks. The statistical correlation factors by categories of rocks only offer rough estimates of the direct strength in tension using the Brazilian tensile strength test data. It is suggested to compare the two methods using models which include the structure of a material. It is shown that when the analysis includes the biaxial stress field, which leads to a decrease in the strength by the Brazilian test as compared with the strength value from the direct tension, as well as when the analysis includes the nonuniformity of the tensile stresses, which brings an opposite effect, the tensile strength values of the two methods are correlated more accurately.

  • Numerical Modeling of Rock Bolt Support in Case of Rheological Behavior of
           Rock Mass in Deformation

    • Free pre-print version: Loading...

      Abstract: The article presents a geomechanical model of a tunnel with rock bolt support. The numerical modeling is performed in ANSYS. The effect of the rock bolt support on the tunnel stability is analyzed with regard to the rheological properties of rocks. The loading and functioning of rock bolts are actualized owing to joint deformation of the rock bolts and enclosing rock mass during their interaction with each other and with the anchoring grouting. The authors discuss feasibility of loss of the load-bearing capacity by the rock bolts because of their fracture. The algorithm of timing of a rock bolt to keep functioning and damage localization is described.

  • Correlations Between Mechanical and Index Properties of Sandstone from the
           Central Salt Range

    • Free pre-print version: Loading...

      Abstract: A study was conducted to uncover the possible correlations among mechanical and index properties of sandstones from formations of Salt Range area, Punjab, Pakistan. For this purpose, sandstone block samples were collected from seven formations of the Salt Range. The samples were prepared for rock testing according to the guidelines set by International Society of Rock Mechanics (ISRM). Defective samples were discarded and those meeting the ISRM specifications were tested for sonic velocities, dry density, porosity, uniaxial compressive strength, tensile strength and elastic constants. Results obtained were then statistically analyzed to find the predictive relationships. The analysis revealed that correlations exist between two groups of tested rocks. The predictive relationships were determined between porosity and static mechanical properties of rocks and between porosity and dynamic mechanical properties.

    • Free pre-print version: Loading...

      Abstract: The effect of various parameters (S:L ratio, duration, temperature and intensity of ultrasonic treatment) on recovery efficiency of zirconium and rare earth elements (REE) in dissolution of silica gel is investigated. The leaching process optimization is performed using the method of Taguchi L9 orthogonal array and the analysis of variance (ANOVA). The recovery of zirconium and REE from silica gel to pregnant solution at the optimized dissolution parameters is 47.95 and 56.17%, respectively. The ANOVA method shows that contribution of ultrasonic treatment in the recovery of zirconium and REE equals 89.6 and 59.6%.

  • Modern Analytical Methods and Research Procedures for Mineral Processing
           Engineering Summary

    • Free pre-print version: Loading...

      Abstract: The rapid development of technology and engineering in recent years caused the need to adopt an integrated and interdisciplinary approach to mineral processing engineering. The relationships between mineralogical characteristics of the raw material and the efficiency and effectiveness of its processing and beneficiation processes become vital, especially concerning selecting processing technologies. Mineralogy determines the energy consumption of grinding processes but also the conditions of the process such as flotation (type and number of reagents, flotation time, environmental parameters of the slurry, etc.) The article shows modern methods of process mineralogy used in the processing of mineral resources at the stage of the process design, its optimization and diagnosis of technical problems in the beneficiation process. Research strategies used in diagnosing issues associated with the processing in the beneficiation plants are discussed as well as research procedures and analysis methods supported by modern process mineralogy tools (QEMSCAN, MLA, EPMA, TOF-SIMS), which constitute modern mineral engineering characterized by an integrated and interdisciplinary approach to processing.

  • Insight into Mineralogy of a Low-Grade Manganese Ore for Separation

    • Free pre-print version: Loading...

      Abstract: In this study, the use of XRF, XRD and other instruments found that the manganese content in the ore was 14.53%, and the main forms were carbonate, iron manganese oxide and manganese oxide. Because of the special magnetic susceptibility of these minerals, the magnetic separation method was chosen to improve the grade of manganese ore, and the conventional magnetic separator of –30 mm and –15 mm was proposed to separate manganese ore, and 4 kinds of concentrates were obtained according to market demand. At the same time, it was found that the grade of middling obtained after sorting was relatively low, and the selection index of \(15\sim 0\)  mm was better than  \(30\sim 0\)  mm. Therefore,  \(15\sim0\)  mm is selected for the re-concentration test of middling. The result shows that the grade of concentrate obtained by re-concentration of middling is 23.26%, which is 2.33% higher than that of non-concentrated ore concentrate, and the comprehensive concentrate obtained can be subdivided 3 different products, which can be flexibly adjusted according to market requirements.

  • The Use of Tecflote Family Collectors in Copper–Nickel Ore Flotation

    • Free pre-print version: Loading...

      Abstract: Tecflote non-ionic organic agents are investigated as potential flotation collectors for copper–nickel sulfide ores. Adsorbability of four Tecflote agents having different-structure alkyl radicals and different numbers of functional groups is analyzed. The efficiency of the agents toward copper- and nickel-bearing minerals is estimated in non-frothing flotation of ore samples treated with chalcopyrite and pentlandite–pyrrhotine. The behavior specificity of Tecflote agents as compared with sulfhydryl collectors is illustrated. Tecflote agents are more active relative to nickel-bearing minerals. The flotation tests prove that inclusion of Tecflote collectors as additives to standard flotation regime enhances efficiency of the process. Partial replacement of xanthate favors higher recovery of copper and nickel in flotation froth at lower recovery of nickel in flotation tailings.

  • Low-Waste Mining Technology for Structurally Complex Deposits with
           Mixed-Type Process Flows of Ore Extraction and Processing

    • Free pre-print version: Loading...

      Abstract: The article presents a package of engineering solutions to ensure an essential increase in overall extraction of useful components in development of structurally complex ore deposits. The efficiency criterion of such mining using mixed-type process flows of ore extraction and processing is proposed to be the highest NPV of extraction and processing of high-grade ore, low-grade ore and mining-and-processing waste within the overall period of mining. The use of this criterion allows setting optimal ranges for cut-off grade to identify the ore types and qualities. Extraction blocks are distinguished by geological types determined based on the texture, structure and material constitution of ores. In a structurally complex extraction block, zones of super rich, rich, crude, poor and super poor ore are delineated. Super rich ore is extracted in the first place and is forwarded to pressure leaching or to leaching-and-adsorption. After disintegration by blasting, the other above-listed ore grades are sent to a processing plant or to heap leaching. This technology enables enhanced overall metal recovery from an extraction block.

  • Study on Granite Crushing Law under Ultrasonic Multi-Parameter Vibration
           Based on Microscopic Damage

    • Free pre-print version: Loading...

      Abstract: With continuous increase of mineral resource exploration depth and high-density development of underground space, and in view of problems such as low efficiency, high cost and large energy consumption in conventional hard rock crushing manners, higher requirements have been proposed for rock crushing techniques for the purpose of prolonging the service life of drilling tools and reducing the cost. Through research methods such as theoretical research, experiments and numerical simulation, the optimal multi-parameter combination of ultrasonic vibration is obtained. On this basis, hard rocks can be rapidly damaged in a certain longitudinal depth, and formation of ultrasonic wave frequency resonance fatigue crushed rocks. Meanwhile, due to heterogeneity of particles in rocks and inhomogeneity of the microstructures, dynamic behaviors conducted by rock particle units under vibration are quite complicated. Through systematic analysis of damage rules and failure mechanisms of cracks inside rocks under ultrasonic wave multi-parameter coupling vibration, provide a theoretical basis for technologies of rock crushing with ultrasonic vibration.

      Abstract: The article describes the studies into the mineralization kinetics of air bubbles with non-activated and activated sphalerite particles 74–100  \(\mu\) m in size in brackish solutions of sulfhydryl collectors. The test collectors were isopropyl potassium xanthate and isopropyl sodium dithiophosphate (Aeroflot), and the test activator was copper sulfate. The tests provided new data on the mineralization kinetics of air bubbles with sphalerite particles in brackish solutions. The mineralization kinetics test procedure and the new data on the air bubble mineralization rate and intensity can be a framework for the science-based selection of flotation agents (collectors, activators, etc.).

  • Mining Complexity Assessment to Substantiate Deformation Monitoring at
           Open Pit Mines

    • Free pre-print version: Loading...

      Abstract: The authors substantiate applicability of type-design practice of geotechnical facilities by their complexity with a view to determining structure and contents of deformation monitoring. It is suggested to exercise the type-design practice using particular characteristics of geological, hydrogeological and geotechnical conditions of mineral mining. Based on the existing regulatory documents and considering the modern scale of open pit mining and the current dimensions of open pits, the system of particular characteristics is shaped for the assessment of open pit mining conditions. The multi-criterion analysis of influence exerted by the particular characteristics on the resultant complexity estimate of an open pit is presented. The deformation monitoring procedure for open pits depending on their mining complexity is proposed. The procedure is tested at Tsentralny open pit mine at the Khibiny apatite–nepheline deposit on the Rasvumchorr Plateau.

      Abstract: The analytical model and numerical program are developed for solving 3D elastic problem on wedge tool penetration resistance in brittle rock mass with regard to the main crack growth. The program testing is described. Its efficiency is proved by comparison with the analytical solution of a problem on equilibrium propagation of a disc-shaped crack in the elastic space with pressure applied in the center of a circle of limited radius. Such solution is a good approximation of the problem on wedge penetration and can be used to estimate the wedge penetration resistance depending on the wedge geometrics, penetration depth and characteristics of the medium.

      Abstract: In view of rapid digitalization in the mining business, the authors highlight some associate problems. The definition of a digital twin is explained, and the difference of a digital twin of a solid mineral deposit from the other digital twins in the industry is described. The key function of a digital twin of a mineral deposit consists in updating of the deposit representation and in the use of the updated data in reasoned decision-making concerning mining development. A digital twin is formed using a set of automation tools. The mining and geological information system MINEFRAME integrates and structures the geology and geotechnology data a solid mineral mining in a unified digital space and, thereby, generates a mining plan based on the actual geological information. The methods of geological and geotechnical modeling, including digital twins, enable enhancement of occupational safety and optimization of mining strategy.

  • Application of Selected Analytical and Empirical Methods to Determine the
           Causes of a Rock Burst Incident Recorded in a Polish Mine

    • Free pre-print version: Loading...

      Abstract: The paper concerns an analysis of the causes of the rock burst that occurred in 2019 in one of the underground hard coal mines in the Upper Silesian Coal Basin (Poland). This incident occurred in the area of an active longwall with complex mining and geological conditions. The operation was linked to natural hazards, with seismic (rock burst) and methane hazards predominating. The recorded seismic activity in the course of the operation was at a high level. Commonly used methods of assessing the state of the rock burst hazard are characterised by the difficulty in predicting the occurrence of tremors which may result in dangerous incidents (rock bursts or relaxation). There is therefore a need to constantly improve methods of forecasting the state of such hazards. The paper presents selected results of the applied analytical and empirical methods, which made it possible to determine the causes of the rock burst and to determine the principles of further exploitation in the area covered by the study.
