  • Model-based Seismic Imaging and Analysis of Karst Water Hazards in Coal
    • Abstract: Abstract Accurate detection of karst water is the premise of karst water disaster control in coal mines. It is difficult to identify karst geological characteristics based on seismic data, so to solve this problem, a digital model including the coal measure strata and complete karst system was established based on the karst status of a coal mine in the Huaibei area of China. The entire process of seismic acquisition, processing, and interpretation was simulated and then the model was restored according to the seismic interpretation. Based on the results, karst identification and water inrush risk prediction were tried. The results allowed the overall karst geological framework, karst cave system, and stratum contact relationships to be restored more truly. Thus, seismic data can provide accurate geological information for large-scale hydrogeological mine exploration.

  • The Use of Accurate Pore Pressure Monitoring for Risk Reduction in
           Tailings Dams
    • Abstract: Abstract Simply monitoring movement of the tailings dam wall does not address the cause of tailings dam failures and will therefore never be an effective method to reduce or prevent failures. Monitoring the causes of failures is more effective. The main cause of tailings dam failure is slope instability, which is caused by too much water in the wrong place. Accurate pore pressure monitoring of the pressure (weight) of water in the tailings storage facility (TSF) slopes and plotting of flow lines beneath and upstream of the TSF can guide and enable early intervention to prevent or delay failure. Remote monitoring linked to artificial intelligence and robotics to turn on pumps and open drains to address and remove the cause of failure can help reduce risk. Installation of multiple point piezometers in an accurate pattern allows the plotting of equipotentials and flow lines in three dimensions. Each TSF is unique and requires its own monitoring design, which should be tailored to match the age, structure, and specific causes of risk. Once understood, the monitoring system can be coupled to a reporting system to significantly reduce the risk of failure at both legacy and active sites.

  • Combining Surface Water with Mine Water to Improve the Removal of Natural
           Organic Matter by Enhanced Coagulation
    • Abstract: Abstract Mixing of near-neutral pH mine water and surface water substantially reduced the reactive portion of the natural organic matter (NOM) in the surface water by enhancing the coagulation process, using alum. The hardness and ionic moieties in the mine water improved the effectiveness of the alum in reducing the NOM concentrations. This is important because the presence of NOM can lead to the fouling of membranes and corrosion in the drinking water plant, and deteriorates drinking water quality by contributing undesirable changes in odor, taste, color. In addition, the presence of NOM can lead to carcinogenic by-products as a result of chlorination. The interactive effects of different operational conditions, i.e. pH, mixing proportion, and coagulant dose, were optimized using a statistical tool. The results affirmed that mixing of this mine water with river water would be an appropriate way to maximize the removal of the reactive part of NOM prior to disinfection and provide good quality drinking water.

  • Shifting the Mind Set: Tailings Management at the Las Cruces Mine
           (Seville, Spain)
    • Abstract: Abstract The Las Cruces copper project has faced a number of important challenges during its 20 year history of development and operations. From the first, the engineering design and planning of the project was highly influenced by the earlier, nearby Los Frailes tailings dam failure and a concern for environmental protection. The successful design, construction, and operation of a surface, dry stacking tailings facility, the first of its kind in Spain, were key factors in regaining the confidence of local communities in the mining industry and in establishing social licence for continued mining. Now, the open pit resources are almost depleted and a new underground operation and renewed hydrometallurgical plant are undergoing permitting to extend the life of the project by more than 15 years, to facilitate mining of primary polymetallic resources beneath the secondary sulphides. This project will require a significant shift in the mind set of all stakeholders involved, including a new approach to tailings management that will allow Las Cruces to benefit from synergies between mine backfilling, tailings disposal, and environmental protection.

  • Water Source Discrimination in a Multiaquifer Mine Using a Comprehensive
           Stepwise Discriminant Method
    • Abstract: Abstract Previously proposed discriminant methods cannot accurately identify water sources in a complex multiaquifer mine. Based on statistical analysis of the water chemistry of samples collected at the Xinji no. 2 multiaquifer coal mine, a comprehensive stepwise discriminant method was proposed for this purpose. Characteristic ion contrast and ion proportional coefficients were applied to aquifers with distinct chemical characteristics to establish a characteristic index discrimination system. Aquifers with small differences in water chemistry were identified by the Fisher discriminant method. Different methods (first simple ones, followed by more complex ones) were used to distinguish the water sources of different aquifers. This approach enabled us to identify water sources for the Xinji no. 2 mine and should be tried for other sites with similar hydrogeological conditions.

  • Circular Economy in Tailings Management
    • Abstract: Abstract Tailings size distribution can be modified to greatly reduce surface storage area and the risk of catastrophic tailings dam failures. Total flotation and backfill technology can even be used to store the tailings underground. In Peru, dynamic neutralization and coagulation technology uses fine tailings as neutralizing and coagulating agents for acid effluent neutralization while the remaining coarse tailings are used as mining backfill. Also, a new technology, HEVA, produces lime and clean CO2 from limestone and the tailings that contain carbonates. The CO2 is used to produce biomass through photosynthesis in aquatic and terrestrial greenhouse environments. One application in the high Andes (4400 m.a.s.l.) proposes to compensate for the area’s natural CO2 deficiency with cheap HEVA CO2 to achieve 100–200% greater productivity to reduce historical poverty in the region.

  • Planning the Dewatering of a Tailings Storage Facility
    • Abstract: Abstract The San Rafael mine in southern Peru produces over 10% of the world’s tin. The decision was made to reprocess some of its oldest tailings, due to their volume and high tin concentrations. This tailing storage facility was partially saturated and required a dewatering process to allow mining. This paper describes the conducted activities for this dewatering, including basic engineering studies focused on hydrogeological characterization of the tailings, recommended tests and modelling to define a detailed engineering design, and developing an appropriate construction strategy. In addition, there were tasks associated with operating the dewatering system, infrastructure maintenance, and a real-time follow-up implementation program to monitor the desaturation. The system’s historical evolution, a year of dewatering, and the beginning of mining activities are reviewed.

  • Mechanism of Water Inrush of a Deep Mining Floor Based on Coupled Mining
           Pressure and Confined Pressure
    • Abstract: Abstract We studied the water inrush mechanism in deep mines using experiments to determine the full stress–strain permeability of different lithologies in deep coal seam floors. We also performed numerical simulations of rock floor failure and confined water uplift variation, fracture evolution, permeability variations of coal seam floor failure, and monitored confined water uplift. The results show that water inrush is related to the coupling of mining pressure and water pressure, which expand after unloading, similar to the way rocks soften in stress–strain permeability experiments after peak stress. This conclusion has been confirmed by field drilling, water injection tests, and numerical simulations. The water-bearing layer of the floor strata can be modified (strengthened) by grouting to reduce confined water flow. Technical measures can be taken to divert pressure from and reduce damage to the floor strata and thereby prevent water inrush through the coal floor.

  • Prediction and Prevention of Water Inrush Hazards from Bed Separation
    • Abstract: Abstract The rock plate (RP) method can be used to identify the size and location of potentially dangerous bed separation space (BSS) in coal mines. The RP method is performed in three steps: (1) The rock strata above the coal seam is simplified as a composite plate calculation model; (2) The deflection of rock strata is expressed as a double trigonometric series and obtained using the energy method; (3) The internal-forces and deformation of the RP are solved to determine the size and location of the BSS based on elasticity and a BSS identification process. This requires that the BSS be unbroken, and the BSS upper rock stratum be an aquifer. In this study, the Yuanzigou coal mine was taken as a study case and the RP method was used to determine the size and location of BSS water (BSS-W) above the coal goaf of working face 1,012,001. BSS usually occurs at the contact surface between hard and soft rock strata; at this mine, BSS-W exists between the Yijun conglomerate and the Anding mudstone formations. The results predicted that when the working face advanced 350 m, the third BSS will break, allowing BSS-W to flood into the goaf. These results were verified by borehole video observation. Therefore, two control methods were used: inclined drainage holes drilled from the roadway and spaced holes drilled from the surface in areas with abundant water. This paper thus provides a way to locate the BSS-W and prevent an inrush hazard.

  • Applying Practical Hydrogeology to Tailings Storage Facility Design and
    • Abstract: Abstract Hydrogeology plays an important role in tailings storage facility (TSF) design. In this paper, we present hydrogeologic considerations for TSF design and operations and some fundamentals for site characterisation during the design phase that can help reduce the severity of groundwater-tailings interactions. Finally, we present examples of tailings-groundwater interactions from TSF design projects and active mining operations around the globe to illustrate our key points. These examples include successful applications of hydrogeologic principles during design and operations, and unexpected interactions between tailings design elements and groundwater where hydrogeology was not properly considered.

  • Electrical Resistivity Imaging Applied to Tailings Ponds: An Overview
    • Abstract: Abstract Geophysical methods based on electrical properties can be used to study tailings ponds studies because a site’s spatial and temporal subsurface electrical resistivity values vary depending on its physical and chemical properties (texture, salinity, metals, water content, temperature, pH, etc.). This paper reviews published case studies in which electrical resistivity tomography (ERT) was successfully used to characterize and monitor tailings ponds.

  • Identification of Flow Zones Inside and at the Base of a Uranium Mine
           Tailings Dam Using Geophysics
    • Abstract: Abstract Potential problems related to a tailings dam’s stability are a matter of concern, especially where structural failure might endanger nearby communities and the environment. The Osamu Utsumi mine, located in the State of Minas Gerais, is currently not operating. The rock-soil tailings dam has water upwelling downstream in the bedrock, with water flux confined to rock fractures. This research was conducted to identify possible flux zones in the base of the dam using DC resistivity and electrical resistivity tomography (ERT). The data acquisition consisted of five ERT lines with 6 m of spacing between electrodes, using a Schlumberger array. The results are presented by 2D and 3D geophysical models comprising measured and processed resistivity values. It was possible to identify a low resistivity zone (5–20 Ωm), whose structural continuity indicates water infiltration in the bedrock under the dam. Moreover, the results do not indicate that erosion is taking place in the interior of the dam, reducing the risk of geotechnical instability and failure of physical integrity.

  • Evolution of Water Hazard Control Technology in China’s Coal Mines
    • Abstract: Abstract We analyzed the regional nature of China’s coal mine water disasters based on three aspects: the main water source, water-conducting passages, and threat level of water hazards. The development of water hazard control technology in China’s coal mines, including exploration and assessment of hydrogeological conditions, water inrush mechanisms, and predictive technology were all reviewed. We then focused our discussion on the calculation theory and methods behind mine inflow prediction, methods of dewatering and depressurizing, and technology for mining under water pressure and water-blocking grouting. Finally, we present the evolving trend of coal mine water disaster prevention and control technology, which is characterized by accuracy, transparency, environmental considerations, informatization, and intelligent technology.

  • A Comparison Between Predictive Tests Results and Natural Weathering in
           the Figueira Mine, in Southern Brazils
    • Abstract: Abstract Many studies on acid mine drainage (AMD) use predictive methods, such as humidity cells (HC), to study this problem, as it is often not possible to predict acid generation from field tests. However, some comparisons of HC testing with reality have proven to be unrealistic. In this study, we compared the results of the HC test with historical data from the Figueira mine, in the State of Paraná (southern Brazil). To carry out the work,we collected a fresh coal tailings sample from the Figueira Mine, and compared monthly measurements of pH and electrical conductivity (EC), and concentrations of Fe, Al, Mn, and Zn, over a 5 year period (from 2013 to 2017) with the predictive test results performed following protocol B of the ASTM D5744-13 (2018) standard. The elements were analyzed by ICP-OES. The pH and EC of the HC test were lower than the field data. The HC test underestimated the concentrations of Fe and Mn, while Al and Zn were overestimated. We believe that the overestimations were due to the aluminosilicate buffering capacity and cation exchange capacity of the soil.

  • Using Statistical and Dynamical Downscaling to Assess Climate Change
           Impacts on Mine Reclamation Cover Water Balances
    • Abstract: Abstract The oil sands industry in Canada uses soil–vegetation–atmosphere-transfer (SVAT) water balance models, calibrated against short-term (<≈ 10 years) field monitoring data, to evaluate long-term (≈60 years) reclamation cover design performance. These evaluations use long-term historical climate data; however, the effects of climate change should also be incorporated in these analyses. Although statistical downscaling of global climate change projections is commonly used to obtain local, site-specific climate, high resolution dynamical downscaling can also be used. The value of this latter approach to obtain local site-specific projections for mine reclamation covers has not been evaluated previously. This study explored the differences in key water balance components of three reclamation covers and three natural sites in northern Alberta, Canada, under future, site-specific, statistical, and dynamical climate change projections. Historical meteorological records were used to establish baseline periods. Temperature datasets were used to calculate potential evapotranspiration (PET) using the Hargreaves–Samani method. Statistical downscaling uses the Long Ashton Research Station Weather Generator (LARS-WG) and global circulation model (GCM) projections of temperature and precipitation. Dynamical climate change projections were generated on a 4 km grid using the weather research and forecasting (WRF) model. These climate projections were applied to a physically-based water balance model (i.e. Hydrus-1D) to simulate actual evapotranspiration (AET) and net percolation (NP) for the baseline and future periods. The key findings were: (a) LARS-WG outperformed WRF in simulating baseline temperatures and precipitation; (b) both downscaling methods showed similar directional shifts in the future temperatures and precipitation; (c) this, in turn, created similar directional shifts in future growing season median AET and NP, although the increase in future NP for LARS-WG was higher than that for WRF. The relative increases in future NP were much higher than the relative increases in future AET, particularly for the reclamation covers.

  • Proper Adhesive Choice Increases Photothermal Float Durability in Mine
           Water Disposal Applications
    • Abstract: Abstract The use of photothermal materials to enhance evaporative water disposal can be limited by material durability, scale formation, and interactions between the photothermal materials and variable water chemistries. Granular activated carbon (GAC) was chosen as a photothermal material based on previous research. Using a custom-built, bench-scale evaporation platform that mimics the solar spectrum and intensity, evaporation trials were performed to determine the effect of water quality, GAC grain size, and float adhesives on water evaporation rates. Adhesives to attach the GAC to HDPE floats were tested for bond strength and durability, and the adhesive’s effects on GAC’s evaporative properties were measured by contact angle, water retention, and surface area analyses. While large differences in durability were observed with the different adhesives, no significant differences were discovered between grain sizes, adhesives, or water quality in the evaporation tests (p > 0.05). Scale formation from three test waters was observed and characterized by SEM and EDS; however, scale did not lead to any significant changes in evaporative performance of the floats. Thus, consistent evaporation rates measured in the bench scale evaporation chamber regardless of GAC grain size, adhesive type, and water quality, indicate the potential versatility of GAC in photothermal water disposal.

  • Groundwater Hydrogeochemical Mechanisms and the Connectivity of Multilayer
           Aquifers in a Coal Mining Region
    • Abstract: Abstract Multiple runoff connections for groundwater supply and water quality evolution mechanisms were disclosed using hydrochemistry, multivariate statistics, stable hydrogen and oxygen isotopes, and inverse hydrogeochemical modeling in a multi-layer groundwater system in a north China coal-mining district. Groundwater quality was mainly influenced by dissolution and weathering of carbonate, silicate, gypsum, halite, and fluorite, as well as cation exchange. Sulfate enrichment in the Carboniferous limestone aquifer may be due to pyrite oxidation, while gypsum dissolution and sewage contribute sulfate to the Quaternary alluvium. The Ordovician limestone groundwater is hydraulically connected to the other two aquifers. Incongruent dissolution of dolomite occurs when the Ordovician limestone water contacts the Carboniferous aquifer, while evaporation occurs when the Ordovician limestone water migrates upward through fractures to the Quaternary aquifer.

  • Feasibility of Co-Treating Olive Mill Wastewater and Acid Mine Drainage
    • Abstract: Abstract Previous tests using a growth medium and olive mill wastewater (OMWW) have shown that it supplies carbon and electron donors suitable for sulphate reducing bacteria (SRB). We assessed the co-treatment of acid mine drainage (AMD) and OMWW using SRB-enriched bioreactors and identified the most abundant bacterial populations present under optimized conditions. The process requires a neutralizing agent to create optimal pH conditions for successful removal of the AMD’s main contaminants. Concentrations of SO42−, Al, Fe, Cu, Zn, and Mn decreased to below Portugal’s maximum admissible values for irrigation waters, and all but Mn were reduced to less than Portugal’s emission limit values (ELVs) for wastewater discharges. Phenol concentrations—the main pollutants in OMWW—dropped to values between 1/10 and 1/5 their initial concentrations in batch tests using mixtures of AMD and OMWW, and to 1/2 their initial concentrations in flow-through tests. The final total phenol concentrations were still above the ELV for wastewater discharges, but phenols are not regulated in irrigation waters, and OMWW is used by some producers to irrigate soils. Six main SRB groups were identified as likely having a fundamental role in the bioremediation process: the genera Desulfovibrio, Sulfurospirillum, and Acetobacter and the families Sphingomonadaceae, Prevotellaceae, and Deferribacteraceae.

  • Microbial Succession Signals the Initiation of Acidification in Mining
    • Abstract: Abstract We characterized the sulfur geochemistry and microbial community structure of seven circumneutral wastewaters from two Canadian nickel mines collected in summer, winter, and spring, in 2014 and 2015. We also established and characterized sulfur oxidizing enrichments for these wastewater samples in two pH corrals of 7–5 and 5–3. Mine 1 exhibited lower contents of total soluble sulfur compounds and reactive soluble sulfur compounds (oxidation state < + VI) relative to Mine 2. Mine 1 also exhibited greater wastewater microbial community diversity with more unique sequences than Mine 2, resulting in clear NMDS differentiation and Bray–Curtis dissimilarity between the two mines’ microbial communities. Proteobacteria dominated all wastewater samples and enrichment communities, ranging between 58–99% of the total of sequences retrieved from the corresponding samples. However, a shift in dominance occurred from primarily Alphaproteobacteria (28–77%) in the circumneutral wastewater communities to Gammaproteobacteria (> 80%) in the moderately acidic enrichment communities. A further pH dependent shift occurred from Halothiobacillus spp. dominating the pH 7–5 enrichments to Thiomonas spp. dominating the pH 5–3 enrichments. These results provide putative biological indicators for better prediction and management of sulfur processes and AMD onset in mining wastewaters.
