The modified Hoek–Brown criterion was employed to derive analytical expressions for the stress distribution in different zones of the surrounding rock and for the radius of the plastic zone, thereby revealing the key factors controlling roadway stability. Based on the postexcavation degradation characteristics, the surrounding rock was divided from the excavation boundary inward into a fractured zone, a plastic softening zone, and an elastic zone, and the corresponding control principles and key techniques for extremely fractured soft-rock roadways were proposed. On this basis, three major control measures were identified: restraining the expansion of the fractured zone through high-prestress support components, mobilizing the bearing capacity of the surrounding rock through an effective support-bearing zone, and reinforcing weak sections to form a continuous bearing ring. Accordingly, a full-section combined control scheme of “high-strength prestressed long-short cables plus floor destressing anchorage” was developed. Considering the characteristics of this support scheme and based on the Hoek–Brown criterion suitable for loose and fractured rock masses, a “coupled superimposed bearing arch” capable of achieving both internal and external load bearing was proposed. This coupled bearing arch unifies the interaction between the support system and the surrounding rock with the radial confining force provided by the support, significantly amplifying the load-bearing capacity of rock bolts and cables. The results indicate that the extent of the fractured zone decreases with increasing uniaxial compressive strength and geological strength index (GSI) of the surrounding rock. Progressive expansion and transformation of the boundary between the fractured zone and the plastic softening zone is identified as the fundamental cause of large-scale rock mass fragmentation and bolt/cable anchorage failure. After applying the combined control scheme, deformation of the 12810 roadway was effectively controlled: The total convergence of the sidewalls was approximately 362 mm, roof subsidence about 142 mm, floor heave about 215 mm, and no large-scale cable ruptures occurred, ensuring roadway stability.</p>","PeriodicalId":12512,"journal":{"name":"Geofluids","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/gfl/7819463","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas predrainage through boreholes is an effective means of gas control, and the effective drainage radius of boreholes is a significant index for gas drainage. Taking Sijiazhuang Coal Mine as the research object, the gas drainage radius of seam 15 at different drainage times have been measured. A gas–solid coupling model for coalbed gas drainage has been established by governing equations between porosity, permeability, stress, and seepage, which was applied to optimize the layout of coalbed gas drainage boreholes. The results show that the drainage radius of conventional boreholes in Sijiazhuang Coal Mine increases with time, namely, 3.0, 4.0, 4.4, and 5.0 m on 35, 70, 100, and 120 days, respectively. The model validation results are consistent with the field measured values, confirming the feasibility of the established model in simulating gas drainage effectiveness. When the borehole spacing is less than or equal to 3 m, the effective drainage rate reaches 100% with no blind zones; when the spacing is greater than or equal to 3.5 m, the effective drainage rate drops below 82.7% and blind zones appear. Therefore, the optimal spacing should be controlled within 3 m. The comparison of layout patterns shows that under the same number of boreholes, the double-row staggered (three-flower) layout has a larger negative pressure acting area and more uniform pressure reduction in the roof and floor compared with the single-row layout, with the time to meet standards shortened from 58 to 55 days, significantly improving the drainage efficiency.</p>","PeriodicalId":12512,"journal":{"name":"Geofluids","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/gfl/7298808","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Orthogonal experimental analysis was introduced to more precisely quantify the impact of various factors on the stress reorientation range in injection-production well groups. The results demonstrate that during production, reservoir stress reorientation is primarily governed by pore pressure and expands over time, with the optimal reorientation timing occurring when pore pressure stabilizes. Different fracturing conditions significantly alter the stress reorientation angle and range, thereby affecting the stress distribution among wells. The stress reorientation range exhibits a positive correlation with fracture penetration ratio but a negative correlation with initial stress ratio, Poisson′s ratio, porosity, and permeability.

Based on the Zhulong river section project of the main canal in Xixiayuan irrigation district, dynamic parameters of soil and rock masses were obtained through field and laboratory tests. Using geotechnical numerical analysis with FLAC 3D software, the constitutive model of sand was selected as the Finn model, and appropriate horizontal natural seismic waves corresponding to engineering site conditions and seismic fortification intensity were input to conduct dynamic numerical analysis on earthquake liquefaction of silty fine sand in canal foundation and characteristics of canal deformation and failure. The results indicate that under seismic action, the maximum excess pore water pressure occurs in the silty fine sand layer at the bottom of the canal embankment. However, due to the high initial stress in this layer, the pore pressure ratio remains low, preventing liquefaction. In contrast, in the channel bottom and the localised areas from the outer slope platform to the toe of the canal embankment, although the excess pore water pressure is relatively low, the effective stress is small, resulting in a higher pore pressure ratio, leading to liquefaction of the silty fine sand layers. Seismic-induced deformation primarily occurs in the embankment and shallow foundation soils and exhibits a symmetric pattern. The deformation and failure of the embankment slope are mainly characterised by seismic subsidence and tensile failure at the crest, as well as horizontal lateral flow deformation at the slope toe. During the calculation process, monitoring points were installed at various locations in the canal embankment and foundation, capturing the dynamic changes in excess pore water pressure, effective stress and displacement at different positions under seismic loading. Based on the analysis of shear strain increment, a continuous shear sliding surface was found to develop within the embankment and foundation under seismic forces, suggesting a risk of overall sliding failure.

Accurate risk prediction remains difficult because of complex geological conditions, limited sample sizes, and the inherent subjectivity in hazard classification. In this study, an interpretable data-driven prediction framework is developed by coupling an Improved Sparrow Search Algorithm (ISSA) with a Deep Neural Network (DNN). A dataset comprising 198 samples collected from multiple gas-bearing tunnel projects is established and carefully preprocessed, including missing-value imputation, outlier treatment, and class balancing. To reduce subjectivity in historical labels, Principal Component Analysis combined with K-Means++ clustering is employed to reassign outburst risk levels. The ISSA introduces multiple enhancement strategies to improve global search capability and convergence stability and is used to optimize key hyperparameters of the DNN. Model interpretability is further enhanced using SHapley Additive exPlanations (SHAP), which quantify feature contributions at both global and individual-sample levels. The proposed ISSA-DNN model achieves an accuracy of 0.91 and an F₁-score of 0.92, outperforming several commonly used machine learning methods.

To mitigate these adverse effects, novel self-cleaning and aftereffect perforation technologies have been proposed; however, their quantitative efficacy under coupled downhole conditions remains insufficiently validated. This study presents a systematic comparative evaluation of these technologies against conventional perforation, utilizing both surface single-target red sandstone experiments and full-scale annular concrete target simulations under high-temperature (147°C) and high-pressure (35 MPa) conditions. The results demonstrate a distinct trade-off between penetration depth and tunnel geometry. While self-cleaning and aftereffect charges resulted in penetration depths 22.9%–25.5% and 1.27%–14.74% shallower than conventional charges, they achieved significantly larger tunnel diameters, increasing by 27.8%–44.4% and 11.6%–21.8%, respectively. This morphological shift led to a net increase in effective perforation cavity volume of 9.7%–12.5%. Crucially, gas permeability tests revealed that self-cleaning and aftereffect technologies retained 65.8% and 38.6% of the original formation permeability, respectively—drastically outperforming the 17.4% retention of conventional perforation. These enhancements are attributed to the secondary high-pressure gas scouring mechanism in self-cleaning charges and the localized shock wave expansion in aftereffect charges.
