摘要: 针对红透山深部断层下巷道围岩破坏诱发的涌水现象,以该矿水文地质条件 为基础,建立了岩体水力学模型,应用岩石破裂过程渗流-应力耦合分析系统 (RFPA$^{\rm 2D}$-Flow)模拟研究了深部断层下巷道围岩破坏过程:裂隙形成、扩展到突水通 道最终贯通形成涌水的全过程. 通过对损伤区分布、应力场和渗流场的演化规律进行分析, 揭示了巷道应力重新分布诱发损伤及渗流涌水规律,对涌水通道进行模拟定位,为红透山铜 矿深部巷道支护防渗设计提供了科学依据.

Abstract: For mining-induced water outburst in deep tunnel of Hongtoushan Copper Mine, a hydraulic model for rock mass in Copper mine is proposed, based on the hydro-geological conditions in Hongtoushan Copper Mine. The Coupling System of Flow {\&} Solid in Rock Failure Process Analysis is applied to simulate and study the whole process of the initiation of fractures, extension and formation of water inrush pathway. With the analysis of damage distribution, stress and seepage field evolution, the process of the evolution from surrounding rock to inrush pathway is clearly revealed, and the water rush pathways are determined. The work can provide a scientific guide for the support and watertight design of tunnel.
