  • Prevention and Control of Water Inrushes from Subseam Karstic Ordovician
           Limestone During Coal Mining Above Ultra-thin Aquitards
    • Abstract: Horizontal directional drilling technology was used to prevent and control water inrushes from the Ordovician limestone strata at the Sangshuping coal mine in the Hancheng mining area by drilling and grouting the contact zone along the top of the aquifer. Considering the hydraulic conductivity of the floor failure zone, we used the modified water inrush coefficient method to estimate the critical thickness of Ordovician limestone that had to be grouted. We carried out directional borehole exploration from both ends of the mining face and combined the results with borehole water pressure tests to determine appropriate grouting techniques and parameters; we then analysed the effectiveness of the grouting. 3-D seismic and ground transient electromagnetics (TEM) were used to detect areas of anomalous resistivity and geologic structure in the mining area, while DC and TEM geophysics were used to detect water-bearing areas ahead of the roadway. After the roadway was developed, TEM, DC resistivity sounding, and audio-magnetotellurics were used to explore water-bearing areas under the roadway and the mine floor. Radio waves were used to detect the structure of the mining face and changes in coal thickness. Finally, based on the results of exploration, an inspection program was devised using conventional boreholes supplemented by directional boreholes to comprehensively evaluate the feasibility of mining under pressure. The study showed that the failure depth of the floor was 15 m and that the top of the Ordovician limestone was no longer water-bearing and was now a relative aquitard. The water inrush coefficient was reduced to less than 0.073 MPa/m, which will ensure safe mining and extend the lower limit of safe mining in the area. This provides a technical reference for prevention and control of Ordovician limestone water disasters in similar coal mines.

  • Prediction of Floor Failure Depth in Deep Coal Mines by Regression
           Analysis of the Multi-factor Influence Index
    • Abstract: A multivariate regression analysis model was developed to predict floor failure depth in deep mines using field measured data from 39 coal mining sites in the eastern mining area of the north China coalfields. A Brillouin optical time domain reflectometry system was built with distributed optical fiber sensors embedded in the floor of a coalface to measure the actual failure depth of the mine floor. The measured and predicted results were in good agreement. This study provides an effective scientific basis for preventing and controlling floor water inrush in deep mines in the north China coalfield.

  • Numerical Simulation of Non-Darcy Flow Caused by Cross-Fracture Water
           Inrush, Considering Particle Loss
    • Abstract: A flow erosion model of water inrush was developed that couples the Darcy, Forchheimer, and Navier–Stokes fields under the theory of continuum mechanics. Water flow and fluidized particles were regarded as single-phase mixed fluids based on the fundamentals of flow transition (aquifer laminar flow to turbulent flow) being the main cause of mine water inrush; the effects of rock disintegration and the coupled effects of flow and erosion were incorporated. The water source of the aquifer, water-inrush channel of the fracture network, and flow path of the slope roadway export were organically connected in a unified flow field. The weak integral forms of the Darcy, Forchheimer, and Navier–Stokes equations were constructed according to the principle of virtual displacement. The convective terms were discretized by the finite volume method and the other terms were discretized by the finite element method; the calculation source program was developed based on the finite element language and its compiler (FELAC). The source program system was used to numerically simulate water inrush in a fractured zone in the Jiangjiawan Mine. It reproduced the entire dynamic process of a water inrush and revealed the distribution and variation characteristics of the pressure field, velocity field, porosity, and concentration, as well as the mechanisms underlying the sudden change in water flow.

  • Assessment of Tailings Ponds by a Combination of Electrical (ERT and IP)
           and Hydrochemical Techniques (Linares, Southern Spain)
    • Abstract: Accumulated mine waste in certain locations in the abandoned mining district of Linares-La Carolina (southern Spain) contain high levels of metals. Therefore, in recent years, many of these tailings ponds have been restored and sealed. This study assessed the efficacy of two geophysical techniques, electrical resistivity tomography (ERT) and induced polarisation (IP), combined with hydrochemical studies, as tools to image the effectiveness of the encapsulation. In the bedrock, ERT profiles distinguished a surficial layer of moderate-low resistivity values (below 80 Ω m), associated with alluvial sands or altered granite, and a deeper zone of high resistivity (up to 1000 Ω m) related to unaltered granite basement. Lateral changes in resistivity were identified inside the upper layer and downstream of the tailings pond. The IP profiles detected local anomalies in the chargeability values (up to 8 mV/V), unusual in granitic rocks. The locations with high chargeability also had low resistivity, which typically indicates the percolation of mining leachates in the underlying altered granites. Integration of geological and geochemical information confirmed this interpretation. This work verified that the combined use of ERT and IP methods were effective for monitoring ancient tailings ponds and for assessing tailings encapsulation.

  • Managing Water to Minimize Risk in Tailings Storage Facility Design,
           Construction, and Operation
    • Abstract: Reducing the amount of water in a milled tailings storage facility (TSF) is the primary way to reduce the risk of a catastrophic failure. In addition, a significant factor influencing the permitting and development of new mines, or the expansion of existing mines, is the limited availability of water in some mineral-rich countries, which has led to recent advances in water resource management and improved operational practices. Water reduction can be used to thicken the slurry to varying degrees of solids content up to a highly thickened, paste consistency using conventional or positive displacement pumps to transport the tailings, or with filters to mechanically reduce the water and convey the tailings by truck or conveyor. This paper suggests a method to optimize water use and to evaluate and reduce project risks at the conceptual development stage for both a thickened TSF and a filtered TSF.

  • Waste Management and the Elimination of Mercury in Tailings from Artisanal
           and Small-Scale Gold Mining in the Andes Municipality of Antioquia,
           Colombia
    • Abstract: Several artisanal and small-scale gold mining (ASGM) sites in Colombia were located and sampled. At each ASGM site, tailings samples were collected and analyzed. Establishing rapport with mining stakeholders and analyzing the samples allowed our team to draw conclusions about the inefficiency of mercury-use in gold extraction and the superior efficiency of centrifugal and gravimetric methods for reprocessing the mining residues produced by artisanal gold miners.

  • A Two-Fluid Simulation of Tailings Dam Breaching
    • Abstract: This paper presents the development and application of a dam breach model, EMBREA-MUD, which is suitable for tailings dams. One of the common failure modes for these structures is breaching due to overtopping, which together with the flow of liquefied tailings, is simulated by the proposed model. The model simultaneously computes the outflow of water and tailings from a tailings storage facility and the corresponding growth of the breach opening. Tailings outflows are represented by a separate non-Newtonian viscous layer, which together with a water layer, represent the two fluid components of the model. The third component represents dam material that can be eroded by the shear forces exerted by either water or mud. The water layer also exerts dynamic and erosional forces and can transport solids eroded from either the mud or dam layer. The model was verified against laboratory cases as well as two field cases reported in the literature, the failures of the Mount Polley tailings dam in Canada in 2015 and the Merriespruit dam in South Africa in 1994. The model results agreed well with the recorded narrative of the events, although in the latter case, careful calibration of one of the model parameters was necessary to obtain a good match.

  • Interpretation of the Failure of the Aznalcóllar (Spain) Tailings Dam
    • Abstract: The mechanisms and causes of the sudden failure of the Aznalcóllar tailings pond were investigated. The dam underwent displacements of up to 55 m along a 700 m length, releasing large quantities of acidic waters and 5.5 million m3 of pyrite and pyroclastic tailings. It was a progressive type of failure, allowed by the brittle response of the pre-consolidated and cemented Guadalquivir blue clays and the high pore pressures left from the incomplete consolidation of the dam’s foundation. Special modelling difficulties were posed by the need to incorporate the strain softening behaviour of the clays. The results show that although the timing of the failure could have been approximated using equivalent ductile properties, predicting the shallow, planar geometry of the failure surface observed would have required a precise representation of the brittle response. The failure triggered liquefaction of the tailings, which accelerated at more than 0.1 g. This transition was modelled by migrating from a coupled effective stress approach employing implicit integration to a total stress formulation using an explicit solver.

  • DAMSAT: An Eye in the Sky for Monitoring Tailings Dams
    • Abstract: During the past decade, there have been a number of catastrophic tailings dam failures. Affordable monitoring systems, as well as methods to assess the risk posed to communities living downstream of these structures, are needed. In recent years the availability and accuracy of remote sensing information has increased, whilst its cost has decreased. This paper provides an overview of DAMSAT, a web-based system that brings together Earth observation and other data to help governments and mining companies monitor tailing dams, and estimate the downstream risks they pose. The methods developed are being piloted in Peru at a number of tailings dams, with the overall goal of improving the decision making process and sharing of information with respect to managing these structures. Engagement with Peruvian stakeholders has shown that DAMSAT provides tools that can help government authorities both reduce the risks and increase the sustainability of mining.

  • Impact of Mine Leachates on a Carbonate Aquifer (SE Spain)
    • Abstract: In October 1966, an intense precipitation event (190 mm in 24 h) broke an old tailings retaining structure in the “El Segundo” mining district in the western sector of Spain’s Sierra de Gador, generating a contaminated flood. The Pb-F rich mixture flowed for more than 12 km through the dry riverbeds, damaging infrastructures and crops. In March, 2010, over 40 years later, 41 samples were collected from boreholes and springs, along with eight sediment samples from near the tailings pond and along the dry riverbeds. The fluoride levels in the area’s groundwater were close to 1 ppm, surpassing the area’s normal geogenic levels, and in some cases exceeding the WHO maximum recommended value for drinking water, despite the time that has elapsed since the event. Less mobile elements, such as Pb and Zn, also had higher concentrations in the area affected by the sludge contamination, but did not significantly exceed the background geogenic values.

  • How to Prevent Flow Failures in Tailings Dams
    • Abstract: Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, a stationary flow regime is attained within a tailings basin. Four temporal and spatial conditions must all be present for a tailing dams flow failure to occur: (1) the tailings must experience contractive behaviour; (2) the tailings must be fully saturated; (3) the effective stress due to static or dynamic load must approach zero; and (4) the shear stress must exceed the tailings residual shear stress. Our results also indicate that the degree of saturation (Sr) is the most influential factor controlling dam stability. The pore-pressure coefficient controls geotechnical stability: when it exceeds 0.5 (Sr = 0.7), the safety factor decreases dramatically. Therefore, controlling the degree of tailings saturation is instrumental to preventing dam failures, and can be achieved using a double drainage system, one for the unconsolidated foundation materials and another for the overlying tailings.

  • Integrated Risk Management in Mining Waste Facilities
    • Abstract: The Mining Association of Canada (MAC) was the first in the world to develop an externally verified performance system for sustainable mining. This paper proposes adopting a management model that integrates the principles described in the MAC models for safe management of mining tailings facilities, including governance structure and decision making, to systematically and rigorously implement the other principles described in the International Organization for Standardization (ISO 14001) Environmental Management Systems standard and MAC Tailings Guide (MAC 2019a) in an integrated manner.

  • Geoenvironmental Study of Gold Mining Tailings in a Circular Economy
           Context: Santa Barbara, Minas Gerais, Brazil
    • Abstract: We characterized the tailings from the Santa Barbara tailings dam, which is located in Minas Gerais, southeastern Brazil, to: (i) identify its chemical, mineralogical, and metallurgical properties, and (ii) perform an environmental evaluation of the water at the surface of the tailings facility. The potential recovery of elements such as Sb, As, and Au was also considered for potential tailings reuse. The water was alkaline, with maximum pH values of ≈ 10, and contained potentially toxic elements, such as Sb (up to 0.500 mg/L), As (up to 0.080 mg/L), and Cu (up to 20 mg/L). Gold enrichment areas were found in the tailings dam, with concentrations up to 0.5 g/t. Alignment exists among tailings management, demand for critical raw materials, and increased interest in the processing of low-grade ores and mining waste, which is important in the context of the circular economy. They suggest that valorisation of tailings, although challenging, can be achieved by economic recovery of the more valuable metals.

  • Pyrite Flotation Separation and Encapsulation: A Synchronized Remediation
           System for Tailings Dams
    • Abstract: Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyrite-free neutral tailings acceptable for placement in the dyke and permanently avoids acid generation.

  • The Use of Accurate Pore Pressure Monitoring for Risk Reduction in
           Tailings Dams
    • 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.

  • Shifting the Mind Set: Tailings Management at the Las Cruces Mine
           (Seville, Spain)
    • 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.

  • Circular Economy in Tailings Management
    • 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: 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.
