Abstract

Aiming at the effect of principal stress rotation (PSR) in gently inclined coal seam roadways, this study has established a strength criterion that comprehensively considers the coupling effects of multiple factors. Through integrated theoretical analysis, numerical simulation, and physical model testing, this study quantifies the influence of critical parameters on support stability, encompassing principal stress deflection angle, bolt support angle, damage factor, principal stress ratio, and friction coefficient. Quantitative analysis demonstrates that parameter sensitivity exhibits the following hierarchy: damage factor > principal stress deflection angle > principal stress ratio > friction coefficient. The investigation determines optimal roof support angles of 45-55°, with diminished angle sensitivity observed under high dip conditions (ψ ≥ 60°). Digital Image Correlation (DIC) and Electro Mechanical Systems (MEMS) fiber optic sensors were utilized to monitor principal stress rotation, providing high-precision measurements of stress field evolution. This analysis reveals asymmetric PSR distribution characteristics in the roof structure, manifesting rotation angles of 84.23° and 58.45° on the left and right sides respectively. These findings facilitate the development of a regionalized differential support methodology. Field implementation validates the theoretical framework, demonstrating substantial improvements in roadway stability.

摘要

针对缓倾斜煤层巷道中主应力旋转（PSR）的影响，本研究建立了一个综合考虑多种因素耦合作用的强度准则。通过综合理论分析、数值模拟和物理模型试验，本研究量化了关键参数对支护稳定性的影响，包括主应力偏转角、锚杆支护角度、损伤因子、主应力比和摩擦系数。定量分析表明，参数敏感性呈现以下层次：损伤因子＞主应力偏转角＞主应力比＞摩擦系数。研究确定了45 - 55°的最佳顶板支护角度，在高倾角条件下（ψ≥60°）角度敏感性降低。利用数字图像相关（DIC）和机电系统（MEMS）光纤传感器监测主应力旋转，提供了应力场演化的高精度测量。该分析揭示了顶板结构中主应力旋转的非对称分布特征，左侧和右侧的旋转角度分别为84.23°和58.45°。这些发现有助于制定区域化差异支护方法。现场实施验证了理论框架，表明巷道稳定性有显著改善。
