However, its application in mining remains underdeveloped due to the unique challenges of mining projects, such as their vast scale, complexity, and heterogeneity. The present study aims to explore the characteristics and potential for adoption of BIM technology in the mining sector and focuses on the generation of a Mine Information Model (MIM) from raw mine data, addressing a critical gap in the current state of digital transformation in the mining industry. We designed a fully automated workflow employing parametric modelling to generate models of as-excavated underground tunnels and geological block models for mining, utilising analytical data from surrounding rock formations. Two case studies utilising real mine tunnel data from Finland were conducted to validate the proposed automated MIM generation workflow. The input raw data includes reality-captured raw data, such as point clouds or mesh models of tunnels, borehole information, and associated design files. Through the application of topology-based parametric objects and script-driven rules, MIMs can be effectively created for mining operations. This research offers significant potential for advancing the Mine Building Information Modelling (MineBIM) concept, supporting machine control, automation, and digital twin applications.

Furthermore, the reloading creep behavior of variable-saturation rocks under cyclic water intrusion was investigated. Finally, a novel model is developed to describe this deformation using principles from damage mechanics and the viscoelastic-plastic theory. The following results were obtained: (1) Instantaneous deformation demonstrated a positive correlation with creep stress levels.

In deep coal seams, abnormally high fluid pressures complicate the accurate quantification of absolute adsorption using traditional models, affecting the assessment of adsorption deformation. To address this, this study conducted synchronous adsorption/desorption and strain testing on coals of varying metamorphic degrees under gas pressures up to 15 MPa. The results indicate that the simplified local density model effectively corrects the absolute adsorption amount. Compared to the smaller experimental errors in particle coal, cubic coal shows synchronized adsorption and strain changes, and the lower mean square error from the thermodynamic strain model fitting confirms its suitability for modeling adsorption deformation. As coal's metamorphic degree increased, the deformation modulus increased, indicating enhanced resistance to deformation. Replacing fugacity with pressure may also overestimate the deformation modulus. Further analysis of strain anisotropy and hysteresis during adsorption/desorption showed that anisotropy primarily arises from the macroscopic bedding structure and heterogeneous composition of coal. Anisotropy indices mainly range from 0.1 to 0.5 and gradually decrease as pressure rises during adsorption. Moreover, both adsorption hysteresis <em>h</em>_<em>a</em> and strain hysteresis <em>h</em>_<em>s</em> decrease with increasing pressure, while the overall hysteresis indices of adsorption and strain vary significantly due to irreversible deformation. For practical applications in coalbed methane extraction, incorporating strain anisotropy and hysteresis into constitutive and permeability equations is essential for optimizing multifield coupling models, thereby facilitating the efficient development of deep coalbed methane resources.</div></div>","PeriodicalId":54941,"journal":{"name":"International Journal of Rock Mechanics and Mining Sciences","volume":"186 ","pages":"Article 106035"},"PeriodicalIF":7.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, only a limited number of cases have been discussed on strength changes in these rocks during water transport processes. In this study, one-dimensional water transport experiments were conducted during the drying process on Neogene tuff samples from Japan. The experiments focused on the unsaturated permeation of the porous media and analyzed the variations in advection and diffusion terms relative to saturation changes at multiple points. During the drying process, water transfer occurred primarily through diffusion, although advection was significant in the early stages to equilibrate the hydraulic head at the center of the specimen. Furthermore, the same tuff samples, with adjusted water content during the drying process, were tested using Brazilian and uniaxial compression methods to examine the variations in strength properties owing to the variations in water content. By comparing these results with the water transport data, we observed that significant alterations in strength occurred after the convergence of the advection term. It was shown for the first time that the decrease in strength of tuff occurs only during the water diffusion phase. These results are expected to be applied to more accurate evaluation of rock mass stability and advanced numerical analysis.</div></div>","PeriodicalId":54941,"journal":{"name":"International Journal of Rock Mechanics and Mining Sciences","volume":"186 ","pages":"Article 105984"},"PeriodicalIF":7.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work studied the effect of 10 wt% HCl and 0.8 M DAP solution on the hardness of rock samples (0.36%–1.31 % porosity and 2.72–17 × 10⁻⁶ μm² permeability) at 25, 80, 140 and 200 °C. The experimental results proved the weakening effect of acid and the strengthening effect of DAP on rock. The mechanism of hardening caused by DAP treatment and the positive effects of high temperature were revealed. As the temperature increased, the chemical reaction between DAP and rock accelerated, resulting in an increase in the amount of reaction products (calcium phosphate) and higher crystallinity, which made the rock harder. Even at ultra-high temperatures (200 °C), DAP treatment remained remarkably effective for very dense rock samples. In addition, the relationship between rock hardness and rock embedding strength was established. The fracture conductivities under different rock hardness were calculated by Nierode-Kruk correlation and numerical method.
