The cusp catastrophe theory is employed to establish a state identification model for the irregular coal pillar-roof system (CPRS) formed by the ARs and re-mining entries. To begin, the state discrimination equation (<em>Δp</em>) for the gradual CPRS is derived, and the critical value at which the system transitions into an unstable state under quasi-static conditions is determined. The results indicated that when 16.49 m ≤ <em>L</em> ≤ 22.63 m (<em>L</em> denotes the equivalent span of the intersection roof) and 0 &lt; <em>R</em>_e ≤ 2.61 m (<em>R</em>_e denotes the width of the elastic zone within the triangular coal pillar), the triangular CPRS is inherently unstable. Similarly, for trapezoidal CPRS configurations where the length <em>L</em>_m (the span of the right-angled trapezoid roof in the propulsion direction) varies from 4.0 to 12.60 m, the system is unstable as well. Subsequently, the model was further enhanced by accounting for the impact of the <em>P</em>_c (advance stress increment load), where a critical criterion for the catastrophic instability of the CPRS was proposed, which represented the external energy required to transition the CPRS from an unstable state to catastrophic instability in different mining stages. After that, the stability degree of the irregular coal pillar was categorized, and a coupling zoning control technology was applied to CPR operations. Field monitoring results demonstrated the effectiveness of the zoning control technology, providing valuable guidance for similar mining practices.</div></div>","PeriodicalId":48505,"journal":{"name":"Underground Space","volume":"20 ","pages":"Pages 119-139"},"PeriodicalIF":8.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2467967424000801/pdfft?md5=da5b193741033ceb8356d3acd410aa05&pid=1-s2.0-S2467967424000801-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142313002","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}

We use the discrete fracture network approach to represent the fracture system in rock obeying a power law length distribution. The LRC consisting of an inner steel lining and an outer reinforced concrete is situated within the rock mass characterised by spatially distributed and intersected fractures. An elasto-brittle constitutive relationship is adopted to characterise the deformation/failure of intact rocks, while the classical Mazars damage model is used to simulate the cracking of concrete linings. For pre-existing fractures in rock, a non-linear stress-displacement formulation is implemented to capture their normal and shear deformations. The 2D model, representing the horizontal cross-section of an LRC with its surrounding rock mass, is subject to a prescribed in situ stress condition. We explore various fracture network scenarios associated with different values of power law length exponent and fracture intensity. We analyse the damage evolution in rock/concrete and tangential strain in the concrete/steel linings. It is found that the damage within the rock mass mainly evolves in the form of wing cracks that emanate from the tips of pre-existing fractures. For damage development in the concrete lining, it is primarily induced by tensile cracking under cavern pressurisation. The damage emerges in the lining sections where pre-existing fractures are located in the tensile region around the cavern and either intersect with the cavern wall or could reach the cavern wall by promoting wing crack propagation.

These processes introduce considerable stability concerns in the surrounding rock formations for underground engineering projects in these regions, highlighting the imperative need for rigorous stability assessments during the design phase to ensure construction safety. This paper introduces an innovative approach for the pre-evaluation of the stability of surrounding rocks in underground caverns situated within high mountain valleys. The methodology comprises several pivotal steps. Initially, we conduct inverse calculations of the ground stress field in complex geological terrains, combining field monitoring and numerical simulations. Subsequently, we ascertain stress-strength ratios of the surrounding rocks using various rock strength criteria. To assess the stability characteristics of the surrounding rocks in the 1^# spillway cave within our project area, we employ numerical simulations to compute stress-strength ratios based on different rock strength criteria. Furthermore, we undertake a comparative analysis, utilizing data from the 5^# Underground Laboratory (Lab 5) of Jinping II Hydropower Station, aligning the chosen rock strength criterion with the damage characteristics of Lab 5′s surrounding rocks. This analysis serves as the cornerstone for evaluating other mechanical responses of the surrounding rocks, thereby validating the pre-evaluation methodology. Our pre-evaluation method takes into account the intricate geological evolution processes specific to high mountain valleys. It also considers the influence of the initial geostress field within the geological range of underground caverns.
