  • Application Overview of Membrane Separation Technology in Coal Mine Water
           Resources Treatment in Western China
    • Abstract: Treating mine water as a resource is the only way to alleviate water shortage and the environmental pollution issues generated at mining sites in areas of northern and western China. By investigating 77 coal mine water treatment stations in western China, we sought to analyze the application status, direct operating costs, and the challenges of using membrane separation technology for this purpose. Here, we introduce the principle underlying membrane separation technology, the influent water requirements, pre-treatment requirements, and typical examples. The importance of membrane separation technology as well as the development prospects of this method are highlighted, and references are provided for the design and management of similar projects.

  • Micro-fracture Precursors of Water Flow Channels Induced by Coal Mining: A
           Case Study
    • Abstract: The evolution of water flow channels typically includes a micro-fracture precursor, especially during deep mining. However, this precursor has not been well characterized. To get more insight into this precursor and its development, the no. 22517 panel in the Dongjiahe coal mine was studied using microseismic monitoring. The energy density of microseismic events was used to identify the spatial location and formation process of the water flow channels. Microseismic focal parameters, such as seismic energy, seismic potency, apparent stress, seismic moment, apparent volume, energy index, and the Gutenberg-Richter b value were determined for the micro-fracture precursors of the water flow channels. The cumulative apparent volume increased significantly and the Gutenberg-Richter b value decreased rapidly, corresponding to the micro-fracture precursor of the water flow channel. Based on the results, a Gutenberg-Richter b value of 0.7 may be an early warning threshold for the formation of a water-flow channel. Finally, a real-time early warning method for water inrush disasters in floor was established based on microseismic monitoring, geophysics, and the water inrush coefficient.

  • Prospective Analysis of Artisanal Mining in the Santa Rita Village:
           Municipality of Andes, Antioquia
    • Abstract: Artisanal and small-scale mining (ASM) of gold has adversely affected the environment and human health for decades, mostly due to excessive use of mercury. With the enactment of the zero mercury law, miners in Columbia began to replace mercury with cyanide and improve their processes. We analyzed the extraction dynamics, based on what had been identified in the municipality of Andes (Colombia) and indexed the pollutant loads of discharges from different small-scale mining gold plants. Gold production for the year 2022 in the municipality of Andes is predicted to total 9811.4 g. None of the sampled small-scale mines currently complies with the permissible parameters for ions and metals in industrial discharges; however, the contamination levels have been reduced for the: La Y mine by 18%, Dorado mine by 13.3%, El Molino by 8.6%, and La Soledad mine by 2.7%. This shows that the ASM operators in the municipality of Andes are beginning to implement cleaner production strategies.

  • Introduction to Special Issue on Mine Water Inrushes: Risk Assessment,
           Mitigation, and Prevention
    • Abstract: Water inrush is a hazard that affects safety and production in many coal mines in China. Chinese mining engineers and scientists have made significant progresses in predicting, preventing, detecting, and mitigating this unique water hazard. The approximately 20 papers in this special issue present the latest research results and practices in six aspects: water inrush risk assessment, numerical simulation for water inrush prediction, high-resolution site characterization technique, rapid determination of water inrush point and water sources, early warning monitoring techniques, and engineering measures that have been used to prevent and mitigate water inrush events.

  • Theoretical and Numerical Investigations of the Failure Characteristics of
           a Faulted Coal Mine Floor Above a Confined Aquifer
    • Abstract: Mechanical models were used to analyze the failure depth of faulted and faultless mine floors based on the limit equilibrium theory of rock mass. In addition, the failure characteristics and water-inrush pathways were numerically investigated. The results were then compared, along with in-situ observations to validate these models. The mining-induced failure zone (an asymmetric “inverted saddle” shape) near the mined-out area was larger in the floor strata beneath the area around the coalface than that near the open-off cut. The maximum fault-induced failure depth was approximately twice that of the intact floor, which was generally equivalent to the in-situ observations. Three characteristic zones in the floor strata were observed during the mining process in the numerical models: a mining-induced failure area, a water-impervious area, and a fault reactivation area. The formation of the failure zone can be roughly divided into an initial stage, a stable stage, and a mutation stage. This study provides an improved understanding for predicting fault-induced mine water-inrushes.

  • Evaluation of Groundwater Inflow into an Iron Mine Surrounded by an
           Imperfect Grout Curtain
    • Abstract: Grout curtains are often used to manage lateral water inflow. However, grout curtains constructed in extremely fractured rocks are not very effective, which poses a challenge for mine drainage and mining operations. So, it is crucial to consider the curtain’s effectiveness when evaluating water inflow. Large-scale pumping tests and groundwater numerical simulation were used in this study to evaluate the water inflow at an iron mine surrounded by an imperfect grout curtain. The effectiveness of the curtain was determined by comparing the hydraulic differences on both sides of the curtain and flow fields at pre- and post-grouting stages and three preferential seepage paths were identified. Given the mine’s complex boundary conditions, the telescopic mesh refinement modeling method was used; regional and local models were established using FEFLOW. The predicted inflow due to the gap in the curtain was 13,880 m3/day, accounting for 37.1% of the total 37,340 m3/day of water that still flowed into the mine. Two countermeasures, surface curtain remediation and underground grouting, were used to decrease water inflow and restore mine productivity.

  • The Role of Macrophytes in Constructed Surface-flow Wetlands for Mine
           Water Treatment: A Review
    • Abstract: Constructed wetlands are a standard sustainable technology in waste and mine water treatment. Whereas macrophytes actively contribute to decomposition and/or removal of wastewater’s organic pollutants, removal of hydrolysable metals from mine water is not attributable to direct metabolic, but rather various indirect macrophyte-related mechanisms. These mechanisms result in higher treatment efficiency of (vegetated) wetlands relative to (unvegetated) settling ponds. Contribution of macrophytes to treatment predominantly includes: enhanced biogeochemical oxidation and precipitation of hydrolysable metals due to catalytic reactions and bacterial activity, particularly on immersed macrophyte surfaces; physical filtration of suspended hydrous ferric oxides by dense wetland vegetation down to colloids that are unlikely to gravitationally settle efficiently; scavenging and heteroaggregation of dissolved and colloidal iron, respectively, by plant-derived natural organic matter; and improved hydrodynamics and hydraulic efficiency, considerably augmenting retention and exposure time. The review shows that constructed surface-flow wetlands have considerable advantages that are often underestimated. In addition to treatment enhancement, there are socio-environmental benefits such as aesthetic appearance, biotope/habitat value, and landscape diversity that need to be considered. However, there is currently no quantitative, transferrable approach to adequately describe the effect and magnitude of macrophyte-related benefits on mine water amelioration, let alone clearly assign optimal operational deployment of either settling ponds or wetlands. A better (quantitative) understanding of underlying processes and kinetics is needed to optimise assembly and sizing of settling ponds and wetlands in composite passive mine water treatment systems.

  • Rapidly Locating a Water–inrush Collapse Column in a Seam Floor: A
           Case Study
    • Abstract: After a mine was flooded by water inrush, a suspected collapse column was speculated based on 3D seismic data, but was not found by drill holes. Seismic source positioning based on different signal arrival times was used to determine the position of the water-inrush point, permitting rapid and accurate grouting and mine restoration. The impact of the water on the roadway roof was used as a continuous and dynamic secondary seismic source, along with surface microseismic monitoring of microseismic events near the inrush collapse column, and two suspected inrush points were rapidly located, which provided the information needed for layout of surface directional detection boreholes. The drilling results indicated that one of the suspected inrush points was a collapse column; its positon had a planar error of 26 m compared to the collapse column controlled by drilling. The inrush point was located 77 m below the seam floor, and the size of the collapse column was 19 m × 7 m. Thus, microseismic monitoring holds promise for rapidly targeting grouting at similar sites.

  • Discussion on Some Topical Issues of Water Prevention and Control in Coal
           Mines
    • Abstract: Effective prevention and control of water hazards in China’s coal mines require that several key issues be addressed. The key issues discussed in this paper are the complex and variable water inrush types in mines, uncertainties in calculation of mine inflow, and the primary mechanism of water hazards resulting from mining-induced bedding separation. Challenges encountered in reinforcement and grouting of the seam roof and floor are also discussed, as well as the risks posed by mine closure. We suggest research areas to better predict and understand the impacts of these issues and propose a direction for improvement of coal mine water control.

  • Characteristics of Water Hazards in China’s Coal Mines: A Review
    • Abstract: China’s coal mines face very complicated hydrogeological conditions and are affected by many complex water hazards. Based on the condition of the coal seams and an analysis of regional hydrogeological and geological conditions, China's coal-producing regions have been divided into six major hazard regions. This paper summarizes the filling conditions and main types of mine water hazards for these six hazard zones. Then, the most common types of water hazards in China’s main coal mining areas (in northern and northwestern China) are analysed. North China’s coalfields face a relatively high risk of water hazards due to the fractured karst aquifers below the coal. Coal mining in the northwestern region is affected by sandstone aquifers above the coal seam, which creates a diverse array of water hazards. This paper illustrates the main characteristics of water hazards in China’s coal mines, and demonstrates the impact of water hazards in China’s coal mines. It also provides a reference for decisions related to coal industry planning and water control technology.

  • Real-Time Monitoring and Early Warning of Water Inrush in a Coal Seam
           Floor: A Case Study
    • Abstract: Monitoring and early warning systems are an efficient way to avoid and mitigate the significant loss of properties and people’s lives caused by water inrush via the coal seam floor, a frequent problem in north China’s deeper coal mines. This paper discusses the basic technical problems, such as the monitoring conditions, indexes and technical system of monitoring and early warning of water inrush in coal seam floor, and selection of monitoring positions. Double criteria for water inrush monitoring and early warning were established based on three factors: crack instability extension, water temperature, and water pressure. Accordingly, a new monitoring and early warning system of the water inrush in coal seam floor was developed using a fiber Bragg grating sensor. This was applied at coal face 2113 of the Chengjiao mine, Henan Province, which lowered the water inrush probability, and so no early warning was necessary. The rationality and effectiveness of this technique were thus verified.

  • 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.
