摘要：

开展金属矿山压气储能硬岩内衬地下硐室上覆岩层隆起破坏研究，对促进压气储能技术规模化、商业化应用具有重要的理论与实践意义。基于建立的岩体声波与地震波速度表征地质强度指标（geological strength index，简称GSI）及扰动参数D 的表达式，并应用Hoek-Brown非线性破坏准则，研究了压气储能高内压效应下金属矿山地下硐室上覆岩层隆起破坏机制，并探讨了相关因素对硐室隆起破坏及极限内压的影响规律。研究结果表明：提出的基于岩体波速Hoek-Brown准则构建的压气储能硐室隆起破坏分析方法，综合考虑了覆岩强度、岩体结构、开挖与爆破扰动效应及侧压力系数等关键因素，较传统方法更具全面性与合理性；随着岩石单轴抗压强度σci、未扰动岩体波速Cp.ud 及扰动岩体波速 Cp.d 的增加，硐室上覆岩层隆起破坏范围逐渐增大，所需的极限内压Pu 则是相应增大，压气储能地下硐室稳定性也相应增强；矿体开挖卸荷导致围岩侧压力系数k 改变，这对压气储能硐室覆岩隆起破坏具有显著影响，随着侧压力系数k 增大，覆岩破裂面角度α 逐渐减小，且减小过程的速率同样呈现递减趋势。研究成果可为压气储能矿山地下硐室围岩稳定性评价和隆起破坏设计准则提供依据。

Abstract:

Studying the uplift failure of overlying strata in lined hard-rock underground chambers in metal mines for compressed air energy storage (CAES) holds important theoretical and practical significance for promoting the large-scale and commercial application of CAES technology. The non-linear Hoek-Brown failure criterion was used to investigate the uplift failure mechanism of the strata overlying underground chambers in metal mines under the high internal pressure of CAES based on expressions of the established geological strength index (GSI) and disturbed factor D for characterizing the velocities of sound waves and seismic waves. Additionally, the influence patterns of relevant factors on the uplift failure and ultimate internal pressure of the chambers were explored. The results show that the proposed analysis method for uplift failure of CAES chambers based on the Hoek-Brown criterion of wave velocities in rocks considers key factors and therefore is more comprehensive and reasonable than conventional methods. These factors include the overburden strength, rock mass structure, excavation and blasting-induced disturbance, and lateral pressure coefficient. As the uniaxial compressive strength of rocks σci , the wave velocity in the undisturbed rock massCp.ud , and wave velocity in the disturbed rock massCp.d  increase, the uplift failure range of those strata overlying the chambers gradually increase and the required ultimate internal pressure Pu  increases accordingly. Meanwhile, the stability of CAES chambers is also enhanced. Due to excavation-induced unloading of ore bodies, the lateral pressure coefficient k of the surrounding rock changes, significantly affecting the uplift failure of those strata overlying the CAES chambers. As the lateral pressure coefficient k increases, the angle α  of fracture surfaces in overlying strata gradually decreases, and the rate of this decrease also exhibits a declining trend. The research provides a basis for the stability evaluation of rocks surrounding underground chambers in mines used for CAES and a design criterion to prevent uplift failure.

Key words: wave velocity in rock mass, Hoek-Brown failure criterion, compressed air energy storage(CAES), caverns in mines, uplift failure, ultimate internal pressure
