Underground coal gasification (UCG) is an emerging energy technology that involves the in situ conversion of coal into syngas through controlled combustion within a subsurface excavation. The geomechanical processes associated with UCG can lead to significant overburden caving and surface subsidence, posing risks to surface infrastructure and groundwater systems. To accurately predict the size of overburden caving zones and associated surface subsidence, a prediction model was developed based on simulation results using discrete element method (DEM) numerical models. The main purpose of developing such a model is to establish a systematic and computationally efficient method for the rapid prediction of the height of overburden caving and its associated surface subsidence induced by underground excavation. The model is broadly applicable to different types of underground excavations, and UCG is used in this study as a representative application scenario to demonstrate the relevance and performance of the model. Sensitivity analysis indicates that excavation span, tensile strength, and burial depth are the primary controls on the height of the caving zone within the ranges of parameters investigated. Rock density is retained as a secondary background parameter to represent gravitational loading and its contribution to the in situ stress level. The derived model was validated using published numerical, experimental, and field measurement data, showing good agreement within practical ranges. To further demonstrate the application of the model developed, the predicted caving geometries were incorporated into finite element method (FEM) models to simulate surface subsidence under different geological conditions. The results highlight that the arch structure formed by overburden caving can help redistribute stresses and thereby reduce surface deformation. The proposed model provides a practical, parameter-driven tool to assist in underground excavation design, environmental risk evaluation, and ground stability management.

Balancing sensitivity and detection range in dynamic pressure monitoring materials remains challenging, with commercial ruby (Al2O3:Cr3+) sensors limited by strong crystal fields, restricting performance under extreme conditions. Here, an innovative strategy utilizing an ordered‐to‐disordered structural conversion in Cr3+ doped Ca(Mg,Sc)(Al,Si)O6 phosphors is introduced. This approach achieves a remarkable blueshift sensitivity of 15.08 nm GPa−1–2.8 times higher than ordered structures and 41 times higher than commercial sensors while maintaining a broad detection range up to 7.5 GPa. Moreover, enhanced structural rigidity notably improves luminescence intensity and thermal stability. The findings establish a robust paradigm for designing high‐performance optical pressure sensors, significantly addressing the traditional trade‐off between sensitivity and detection range, showing promising applications in geological exploration and aerospace fields.

Concrete materials exposed to sulfate-rich geological environments are prone to structural durability degradation due to chemical erosion. Silane-based protective materials can enhance the durability of concrete structures under harsh environmental conditions. This study investigates the evolution of acoustic emission (AE) precursor characteristics in silane-protected, sulfate-eroded concrete specimens during uniaxial compression failure. Unlike existing research focused primarily on protective material properties, this work establishes a novel framework linking “silane treatment–AE parameters–failure precursor identification”, thereby bridging the research gap in damage evolution analysis of sulfate-eroded concrete under silane protection. Uniaxial compressive strength tests and AE monitoring were conducted on both silane-protected and unprotected sulfate-eroded concrete specimens. A diagnostic system integrating dynamic analysis of the acoustic emission b-value, mutation detection of energy concentration index ρ, and multifractal detrended fluctuation analysis (MF-DFA) was developed. The results demonstrate that silane-protected specimens exhibited a distinct b-value escalation followed by an abrupt decline prior to peak load, whereas unprotected specimens showed disordered fluctuations. The mutation point of energy concentration ρ for silane-protected specimens occurred at 0.83 σc, representing a 9.2% threshold elevation compared to 0.76 σc for unprotected specimens, confirming delayed damage accumulation in protected specimens. MF-DFA revealed narrowing spectrum width (∆α) in unprotected specimens, indicating reduced heterogeneity in AE signals, while protected specimens maintained significant multifractal divergence. ∆fα peak localization revealed that weak AE signals dominated during early loading stages in both groups, with crack evolution primarily involving sliding and friction. During the mid-late elastic phase, crack propagation became the predominant failure mode. Experimental evidence confirms the engineering significance of silane protection in extending service life of concrete structures in sulfate environments. The proposed multi-parameter AE diagnostic methodology provides quantitative criteria for the safety monitoring of protected concrete structures in sulfate-rich conditions.

Slope failures and rock mass movements are continuous geomorphic processes, particularly in a dynamically charged terrane like the Himalaya. Thus, failures emanating from weak geology, hydrogeology and anthropogenic disturbances are aplenty. Present research evaluates slope stability in the vicinity of Malling Nala, along NH-505 in Himachal Pradesh, India. For the two most vulnerable sections in the study area, geo-mechanical and structural attributes have initially been ascertained. Field surveys and laboratory tests identified weak and weathered mica schist and gneissic rocks in the study area. Kinematic analysis, Rock Mass Rating (RMR), Geological Strength Index (GSI), Slope Mass Rating (SMR), modified Global Slope Performance Index (mGSPI) led to determination of possible failure mechanism and rock mass behaviour. Finite element analysis provided a comprehensive understanding of slope behaviour under various conditions, highlighting significant shear strain and displacement in both sections. As noticed from the field and classification schemes, planar and localized bench failures were established. Slope section L-1 was found to collapse under saturated water condition, manifesting the influence of snow melt. The findings indicate that both natural and human factors are causing instability. Effective risk management and mitigation strategies are essential to maintain the stability and reliability of this critical frontier region.

The multiscale pore-fracture interface in coal forms the fundamental physical basis governing both coalbed methane (CBM) storage-transport behavior and CO2 geological storage efficiency. This review systematically discusses the principle of small angle scattering (SAS) technology in the analysis of coal matrix pore interface, and focuses on the frontier application of coal-fluid interface in terms of geometry, physicochemical properties and dynamic evolution. Results indicate that SAS can nondestructively quantify the entire pore system, including closed pores. Moreover, the predominance of closed pores in quantity and distribution is strongly affected by coal type and tectonic stress. The unique advantages of in-situ SAS technology in real-time tracking of interface dynamics and complex response mechanisms (such as expansion/contraction, pore damage and structural rearrangement of coal matrix under external fields such as gas adsorption, stress loading and pyrolysis) are analyzed. Through the interface fractal, SAS provides key parameters for quantitative description of interface complexity and its internal correlation with coal chemical composition. The application of "contrast-matching small-angle neutron scattering" (CM-SANS) in visualization of fluid accessibility, the key role of time-resolved small angle scattering technology in capturing instantaneous dynamic structural response of rock mass, and the cutting-edge technology of multi-scale and multi-dimensional data fusion are systematically discussed. The purpose of this review is to provide robust micromechanical support for understanding the coal-fluid interaction, thereby promoting innovation in energy and environmental engineering technologies such as CBM efficient development and carbon capture, utilization, and storage (CCUS).

The Mw5.7 Parker Butte earthquake occurred on 09 December, 2024, ~24 km NNE of Yerington (western Nevada, USA) due to sinistral slip on an unmapped ENE-striking fault. Field reconnaissance and a drone survey were conducted within <1-8 days and ~1 month, respectively, after the earthquake. We observed a lack of surface rupture above the ENE-striking plane of the mainshock and most aftershocks, as well as surface fracturing along a NW-trending lineament orthogonal to the mainshock. Shaking effects included minor sediment failures, liquefaction features, and short-lived fracturing and refreezing features in ice on the Walker River and agricultural channels. Damage to infrastructure was minimal, only settlement and cracking of one bridge abutment fill prism. We estimate ground motions of up to 0.4 g and 23 cm/s. These observations provide valuable data about the effects of moderate magnitude earthquakes and highlight the importance of coordinated multidisciplinary geodetic, seismologic, and field geologic responses. The orthogonal faults indicated by the mainshock and the secondary surface fractures are part of a pattern in the region, where orthogonal faults have slipped in several historical earthquake sequences, establishing this as a common style of faulting within the complex network of faults that comprise the Walker Lane.

ObjectiveChina boasts abundant coalbed methane (CBM) resources, which serve as a crucial replacement for the reserve growth and production addition of natural gas resources. In recent years, CBM exploration and production have gradually expanded into deep, thin coal seams, which, however, are characterized by strong heterogeneity, ultra-low permeability, high in situ stress, and complex enrichment patterns. Therefore, the exploration and exploitation of deep, thin coal seams face challenges such as inadequate geological theories, poor adaptability of key technologies, and low investment returns, which hinder large-scale commercial CBM production. MethodsFocusing on the exploration and exploitation practice of middle-deep, thin coal seams in the Yanchuannan CBM field within the Ordos Basin, this study systematically analyzed the geological characteristics of the CBM field, summarized the primary factors controlling CBM enrichment and high productivity, and established a series of geology-engineering integrated technologies for efficient exploration and exploitation of middle-deep, thin coal seams. ResultsThe Yanchuannan CBM field contains two structural belts, namely Tanping and Wanbaoshan, which exhibit significantly different sedimentary environments, lithotypes and coal quality, reservoir quality, preservation conditions, and in situ stresses. Nevertheless, this CBM field generally shows middle-deep, undersaturated, low-temperature, low-pressure, thermogenic high-quality CBM reservoirs. The production characteristics of the CBM field are governed by fracturing performance. Specifically, gas wells subjected to conventional guided fracturing exhibit late gas shows and production addition combined with limited single-well productivity and recoverable reserves. In contrast, gas wells subjected to fracturing with fractures effectively propped demonstrate rapid production addition and high single-well productivity and recoverable reserves. By integrating dynamic and static analyses, this study gained a geological understanding of four-element coupling for the high productivity and enrichment of CBM in medium-deep coal seams, highlighting sedimentation-controlled coal distribution, preservation-controlled enrichment, in situ stress-controlled permeability, and effective stimulation-controlled productivity. An indicator system for the quantitative evaluation of geology-engineering “dual sweet spots” was developed to guide play fairway selection. Multi-scale pore-fracture characterization technology was established, enabling the quantitative characterization of reservoir spaces on the centimeter, millimeter, micrometer, and nanometer scales. The key technology based on geological modeling and numerical simulation integration ascertained the types and distribution patterns of residual gas. This technology can guide well pattern adjustments in residual gas enrichment zones, thus improving the production ratio and recovery of reserves. By highlighting the suitability of the well pattern and fracture networks, this study established a well pattern – fracture network – productivity – economic benefit integrated strategy tailored to varying geological conditions. To address challenges posed by thin coal seams and great structural fluctuations, this study established the horizontal well guidance – fracturing – production integrated technology for well completion in thin coal seams while considering the requirements of well drilling and completion, fracturing, and production. Through multiple rounds of research and iterative optimization based on a deepened understanding of coal properties, this study developed optimized fracturing with fractures effectively propped characterized by the preflush of high-volume fracturing fluids for longer fractures, variable injection rates of fracturing fluids for fracture height control, and multi-sized proppants for propping multi-scale fractures. The advancement in fracturing technologies shifted the production philosophy from slow and long-term drainage to optimal rapid production addition, leading to the formation of the production system characterized by four stages, two pressuring, and three controlling factors. A "node-region-center" three-level pressure boosting model was developed to maximize productivity. ConclusionsGuided by these advancements, the Yanchuannan CBM field has achieved stable production growth and significantly increased single-well productivity, with the daily production of a single directional well increasing to 1×104 m³/d from 0.1 m³/d and that of a single horizontal well rising to (2.5‒6.0) × 104 m³/d from (0.5‒0.6) × 104 m³/d. These suggest effective fracturing performance and commercial production. This study serves as a valuable reference for the commercial production of similar deep, thin CBM resources in China.

Understanding the connection between structure, dynamics, and fragility, the rate at which the relaxation time grows with decreasing temperature, is central to unravelling the glass transition. Fragility is often associated with dynamic heterogeneity, implying that if structure influences dynamics, more fragile systems should exhibit stronger structure dynamics correlations. In this study, we test the generality of this assumption using: Lennard Jones (LJ) and Weeks Chandler Andersen (WCA) systems, where fragility is tuned via density, and a modified LJ (q,p) system, where fragility is varied by changing the potential softness. We define a structural order parameter based on a mean field caging potential and analyse energy barriers at both macroscopic and microscopic levels. While the macroscopic free energy barrier slope correlates with fragility, the microscopic free energy barrier does not show a consistent trend. Instead, it exhibits a strong correlation with a structure dynamics correlation measure obtained from isoconfigurational ensemble simulations. Interestingly, the two systems showing the highest structure dynamics correlation, LJ at rho = 1.1 and the (8,5) model, are respectively the least and most fragile within their classes. These systems exhibit broad mobility distributions, large non Gaussian parameters, yet low four point susceptibilities, suggesting a decoupling between spatial correlation length and mobility contrast. Both systems lie in the enthalpy dominated regime and are close to the spinodal, pointing to mechanical instability as a source of heterogeneity. Our results reveal that structure dynamics correlation is more closely linked to the contrast in individual particle mobility than to the spatial extent of dynamic correlations that typically scale with fragility.

Salt halokinesis and the widespread development of salt domes in the southwest of the Arabian Gulf have significantly influenced the regional stress regimes, resulting in diverse and complex fracture patterns, particularly within the tight carbonate reservoirs of the Upper Jurassic (Noufal and Shebl, 2019). These fractures play a critical role in reservoir performance, yet their characterization remains a challenge due to the multi-phase tectonic overprints and the structural complexity introduced by salt-related deformation (Fig. 1). This study aims to investigate the fracture system developed above salt domes under Jurassic rifting, Late Cretaceous transtension, and Tertiary compression. By integrating seismic attributes, borehole imaging logs, and structural evolution analysis, we construct a conceptual fracture model to interpret local fracture patterns and validate them against dynamic data. The results demonstrate that fracture intensity and geometry vary with structural position around the salt dome—major fractures concentrate on the flanks in oval geometries, while crests remain less fractured. Additionally, NW-SE en-echelon fractures from Late Cretaceous transtension dominate areas away from the dome, and their overlap with salt-induced fractures creates highly complex systems in transitional zones. This work provides a practical workflow and geological insights for understanding and predicting fracture development in salt-influenced tight carbonate reservoirs.

The Lower Cretaceous Wara, Mauddud and Nahr Umr reservoirs in Bahrain's Awali Field present complex depositional and structural challenges for optimal field development planning (FDP). Wara, Mauddud and Nahr Umr, commonly known as Bahrain zone, are the most important oil-producing group found in Bahrain's Awali Field (Al-Muftah, Vargas, Murty, & Abdulwahab, 2007). Discovered in 1932, the Bahrain Oil Field was the first in the Gulf region and has now reached an advanced stage of development (Konwar, AlOwainati, Nemmawi, Dowen, & Almuntaser, 2020) which increase the necessity of a proper reservoir modeling for effective field development plan. This study adopts an integrated multidisciplinary approach, utilizing advanced 3D geological static modeling techniques by incorporating seismic, well log, core, and production data. Detailed geostatistical modeling and iterative validation workflows captured reservoir heterogeneities and improved static-to-dynamic model alignment. Key results include enhanced prediction of fluid flow behavior, optimized well placement, and a significant reduction in subsurface uncertainties, all of which contribute to better recovery strategies for the Wara, Mauddud, and Nahr Umr reservoirs. This work advances regional geological modeling practices and contributes critical knowledge applicable across carbonate and clastic reservoirs in the Middle East.

In this study, we propose a dynamic fractal dimension modeling (DFDM) framework that integrates image analysis, wavelet-based fractal methods, and structural fractal geometry to quantify the evolution of pore complexity. Unlike conventional static fractal approaches, our method captures time-dependent scaling laws and captures the spatiotemporal evolution of pore networks. The results demonstrate that dynamic fractal dimensions provide a robust descriptor of multi-scale heterogeneity, effectively bridging pore-scale processes with reservoir-scale behavior. This framework not only advances the theoretical understanding of fractal pore dynamics but also establishes a predictive tool with potential applications in unconventional hydrocarbon recovery, geological CO2 sequestration, and multi-phase flow in porous media.

<p>Humans change climate in many ways. In addition to greenhouse gases, climate models must therefore incorporate a range of other forcings, such as land use change. While studies typically investigate the joint effects of all forcings, here we isolate the impact of afforestation and deforestation on winds in the lowermost 350 m of the atmosphere to assess the relevance of land use change for large-scale wind energy assessments. We use vertically resolved sub-daily output from two regional climate models instead of extrapolating near-surface winds with simplified profiles. Comparing two extreme scenarios, we report that afforestation reduces wind speeds by more than 1 m s<span class="inline-formula">⁻¹</span> in many locations across Europe, even 300 m above ground, underscoring its relevance at hub heights of current and future wind turbines. We show that standard extrapolation with modified parameters approximates long-term means well but fails to capture essential spatio-temporal details, such as changes in the daily cycle, and it is thus insufficient to estimate wind energy potentials. Using adjacent climate model levels to account for spatio-temporal wind profile complexity, we report that wind energy capacity factors are strongly impacted by afforestation and deforestation: they differ by more than 0.1 in absolute terms and up to 50 % in relative terms. Our results confirm earlier studies showing that land use change impacts on wind energy can be severe and that they are generally misrepresented with common extrapolation techniques.</p>

Civil infrastructure constructed with, buried in, or underlain by expansive clays is affected by high volumetric changes, especially because large-scale facilities are spatially distributed. This research focused on determining spatial variability during the shrinkage testing of expansive clays. An initially saturated sample (600 mm in diameter) of a high-plasticity clay was exposed to desiccation and thoroughly monitored over five months. The results indicated an expansive clay (30% smectite and 14% illite) in alkaline-pore water (695 mg/L Na⁺ and 1150 mg/L SO₄²⁻) for developing a dispersive soil fabric. The vertical shrinkage in the intact-soil portion was unchanged (remaining at 114 × 10⁶ mm³) in the first 10 days, sharply decreased the initial volume by 30% (up to 280 mm or 80 × 10⁶ mm³) in 68 days, and slowly decreased the initial volume by 40% (up to 240 mm or 68 × 10⁶ mm³) in 145 days. Furthermore, the soil temperature was found to be 10% lower than the air temperature, whereas the relative humidity within the cell was found to be 30% higher than that outside the cell. The soil showed an initial prominent central ridge with a few cracks that gradually evolved into a distinct crack pattern with equal-sized and irregular soil chunks. The average soil surface showed no volume reduction up to 18 days and a subsequent linear reduction, reaching 25% of the initial soil volume by the end of the test.

Dynamic and structural heterogeneities play an important role in glass transition phenomena and in the formation of amorphous structures. Since structure and dynamics are mutually related, it is expected that there exists some relation between them; however, this relation has not been characterized by a direct experiment. Elucidation of this relation is the key to identifying the structure responsible for the rapid freezing of atomic motion during the glass transition. In this study, we simultaneously observed the dynamic and structural heterogeneities near the glass transition temperature in Zr50Cu40Al10 using five-dimensional scanning transmission electron microscopy, which is capable of recording the spatiotemporal distribution of electron diffraction pattern. Dynamic and structural heterogeneities were visualized with sub-nanometer resolution upon heating in situ, and a spatial correlation between them was observed up to the glass transition temperature. Simultaneous measurements of dynamic and structural heterogeneities directly revealed that the ordered atomic structure had slow dynamics and that the order decreased with temperature.

Adaptive structures are of interest for their ability to dynamically modify mechanical properties post fabrication, enabling structural performance that is responsive to environmental uncertainty and changing loading conditions. Dynamic control of stiffness is of particular importance as a fundamental structural property, impacting both static and dynamic structural performance. However, existing technologies necessitate continuous power to maintain multiple stiffness states or couple stiffness modulation to a large geometric reconfiguration. In this work, reversible lamination of stiff materials using Gecko-inspired dry adhesives is leveraged for bending stiffness control. All stiffness states are passively maintained, with electrostatic or magnetic actuation applied for ~1s to reprogram stiffness. We demonstrate hinges with up to four passively maintained reprogrammable states decoupled from any shape reconfiguration. Design guidelines are developed for maximizing stiffness modulation. Experimentally, the proposed method achieved a stiffness modulation ratio of up to 14.4, with simulations showing stiffness modulation ratios of at least 73.0. It is anticipated that the stiffness reprogramming method developed in this work will reduce energy requirements and design complexity for adaptation in aerospace and robotics applications.

The links in many real networks are evolving with time. The task of dynamic link prediction is to use past connection histories to infer links of the network at a future time. How to effectively learn the temporal and structural pattern of the network dynamics is the key. In this paper, we propose a graph representation learning model based on enhanced structure and temporal information (GRL\_EnSAT). For structural information, we exploit a combination of a graph attention network (GAT) and a self-attention network to capture structural neighborhood. For temporal dynamics, we use a masked self-attention network to capture the dynamics in the link evolution. In this way, GRL\_EnSAT not only learns low-dimensional embedding vectors but also preserves the nonlinear dynamic feature of the evolving network. GRL\_EnSAT is evaluated on four real datasets, in which GRL\_EnSAT outperforms most advanced baselines. Benefiting from the dynamic self-attention mechanism, GRL\_EnSAT yields better performance than approaches based on recursive graph evolution modeling.

Abstract The Central-Eastern part of the High Atlas is dominated by carbonate of Mesozoic age which is affected by the Alpine Orogeny. The deformation manifest in area by different geological structures. The analysis of these later lead to their classification in different category for understanding the geodynamic of the area. This study focuses to map structural lineaments in the Central-Eastern High Atlas using two types of Radar data: Synthetic Aperture Radar (SAR)/Sentinel 1B with polarization (VV + VH) and Advanced Synthetic Aperture Radar (ASAR)/Envisat with polarization (VV + HH). This research aims to demonstrate the utility of Radar data for extracting structural lineaments in carbonate deposits. In this work, two techniques of processing data are used: First, the automatic extraction technique, we are employing the Algorithm Line Module of PCI Geomatica program, after the enhancement of images by applying the mean Co-occurrence filter. Second, the manual extraction technique, it was accomplished by applying directional filters with four directions (N00°, N45°, N90° and N135°) in order to highlight linear structures, then trace the detected lineaments. The synthetic maps of structural lineaments are developed by the two techniques. They are validated by using the lithologic maps extracted from Landsat Operational Land Imager (OLI), the previous researches in the study area, shaded relief extracted from ASTER Global Digital Elevation Model (GDEM), and field investigation data. The results present a good correlation between the direction of structural lineaments extracted from the satellite images and the field measurements. Therefore, the directions of lineaments extracted are N-S and E-W, NE-SW and NW-SE, especially the abundance of the direction N-S. This last one is perpendicular with the major faults. The density of structural lineaments in the study area is controlled particularly by the lithological nature and dynamic evolution, where the concentration is high in the Liassic carbonates. The geostatistical and spatial distribution of the structural lineaments led us to conclude that different tectonic factors are responsible for the distribution of lineaments in the surface of the study area. The comparison of two types of radar data shows that Envisat data is more efficient in the manual extraction than Sentinel 1B data. However, Sentinel 1B data is more efficient in the automatic extraction than Envisat data. This work identifies several families of structural lineaments which can be determined the tectonic phases of the Alpine orogeny affected the intracontinental Atlas basin.
