This study investigates the decomposition mechanisms of iron ore and iron-bearing minerals as pathways to low-carbon iron production. In compliance with sustainable mining principles, decomposing iron-bearing minerals below their melting points suppo...
Cement-sheath integrity is a critical component of long-term wellbore isolation during multistage hydraulic fracturing (MSHF), where repeated pressure and temperature changes, casing deformation, formation heterogeneity, and interfacial discontinuiti...
Coal mine backfilling mining technology has developed rapidly in recent years. Composite backfilling technology, which integrates two single backfilling methods, is an approach that achieves multiple engineering objectives, including improved backfil...
This study investigated the influence of high-energy milling and leaching conditions on copper extraction from an industrial copper concentrate obtained from the Balkhash copper smelter. The concentrate was subjected to high-energy milling in a plane...
This research examines transforming contaminated mining waste into mineralogically stable material using density separation and high-temperature settling. Samples with elevated metal concentrations were collected from century-old landfill sites, sepa...
The global mining sector is evolving rapidly, making it increasingly important to monitor its activities and associated emissions in support of sustainable development. In this paper, we use nitrogen oxide (NOx) emissions derived from satellite obser...
Calcined iron ore production is of strategic importance; however, it is associated with considerable environmental burdens due to its high carbon footprint. In this study, the environmental impacts of calcined iron ore production were evaluated using...
Fuzzy-based methods have become increasingly relevant in rock engineering because of their ability to represent uncertainty, imprecision, and gradual transitions inherent in geological and geotechnical information. This study presents a comprehensive...
This study analyses the impact of mining activities on water scarcity in two contrasting mining regions: Zaragoza, Colombia, and Qabatiya, Palestine. Despite significant climatic and hydrological differences, both regions face substantial pressures o...
Roadway surrounding rock stability under high in-situ stress is a core challenge in mining geomechanics. This paper presents an empirical and analytical study on the temporal-spatial evolution of acoustic emission (AE) during fracture of raw coal spe...
Small borrow pits in agricultural landscapes are difficult to monitor because exposed mining surfaces resemble bare cropland, extraction is intermittent, and production records are often limited. This study characterized borrow materials in Indramayu...
Regional classification of dominant discontinuity sets supports open-pit slope characterization, but dip direction is circular and should not be analyzed as a linear variable. We reanalyzed 73 area-level records from 72 nominal survey areas at the Da...
Prior estimation of the distance at which detonation pressure reaches a critical threshold is relevant for defining borehole separations and reducing the risk of damage to electronic detonators in underground mining. Empirical attenuation relationshi...
Convolutional neural networks (CNNs) have shown considerable potential for mineral prospectivity mapping (MPM); however, their predictive performance largely depends on appropriate hyperparameter optimization. In practice, hyperparameters are commonl...
The transition to battery electric vehicles (BEVs) in underground mining offers an opportunity to eliminate direct combustion emissions and optimize ventilation, but it introduces new challenges for emergency management and operational safety. This s...
Tailings ponds associated with the beneficiation of low-grade sulphide ores are a recognized source of acid mine drainage (AMD) and heavy metal contamination in receiving watercourses. This study assesses the physicochemical quality of process water...
Poland is the largest hard coal producer in the European Union. Changes observed during the energy transition, undertaken to slow climate change, is reducing demand for fossil fuels. The restructuring of the hard coal mining industry in Poland is ada...
Rock strength is a key parameter for mine planning and operational optimization, but conventional laboratory testing is costly and provides limited spatial coverage. This study develops a methodology for classifying operational rock-strength classes...
Historical mining districts contain heterogeneous waste accumulations whose spatial distribution and characteristics complicate environmental assessment and rehabilitation planning. This study develops an integrated, unit-based methodology for the ca...
Blast-induced ground vibration is traditionally predicted using empirical scaled-distance equations or numerical simulations driven by simplified analytical loading functions. Although dynamic finite element modeling has significantly advanced the un...
