For the first phase shaft project in the underground mining of Aurora Gold Mine, a discrete element method software EDEM was adopted, and a water-rock-soil coupled model for instability of shaft surrounding rock was established using the smoothed particle hydrodynamics discrete element coupling method (SPH-DEM), for investigating the instability evolution process of strongly weathered surrounding rock under effect of seepage. The results show that the surrounding rock of the shaft become significantly instable within 2-6 s, and the average moving velocity increases firstly and then decreases, peaking at 0.155 m/s; the fluid force acting on the shaft wall fluctuates sharply during 0-2 s and then gradually stabilizes. The shaft wall suffers large scale shallow abrasion, with a final wear area of 17.404 43 m2 and volume of 0.013 31 m3. Numerical simulation shows that the angle of repose for the collapsed shaft surrounding rock is 25°, presenting a relative error of only 1.88% compared to the on-site practical measurement, which has verified accuracy and practicability of such SPH-DEM method.

以奥罗拉金矿地采一期竖井工程为依托，采用离散元软件EDEM，基于光滑粒子法-离散元（SPH-DEM）耦合方法构建水-岩-土壤耦合的竖井围岩失稳模型，研究强风化围岩在渗透作用下的失稳演化过程。结果表明：竖井围岩在2~6 s内失稳显著，平均移动速度呈先升后降趋势，峰值达0.155 m/s；井壁所受流体力在0~2 s剧烈波动后逐渐趋稳，井壁遭受大范围浅层磨蚀，最终磨损面积达17.404 43 m2、体积为0.013 31 m3；数值模拟得出竖井围岩坍塌堆积角为25°，与工程实测结果相对误差仅1.88%，验证了SPH-DEM方法的准确性和实用性。

以奥罗拉金矿地采一期竖井工程为依托，采用离散元软件EDEM，基于光滑粒子法-离散元（SPH-DEM）耦合方法构建水-岩-土壤耦合的竖井围岩失稳模型，研究强风化围岩在渗透作用下的失稳演化过程。结果表明：竖井围岩在2~6 s内失稳显著，平均移动速度呈先升后降趋势，峰值达0.155 m/s；井壁所受流体力在0~2 s剧烈波动后逐渐趋稳，井壁遭受大范围浅层磨蚀，最终磨损面积达17.404 43 m2、体积为0.013 31 m3；数值模拟得出竖井围岩坍塌堆积角为25°，与工程实测结果相对误差仅1.88%，验证了SPH-DEM方法的准确性和实用性。

For the first phase shaft project in the underground mining of Aurora Gold Mine, a discrete element method software EDEM was adopted, and a water-rock-soil coupled model for instability of shaft surrounding rock was established using the smoothed particle hydrodynamics discrete element coupling method (SPH-DEM), for investigating the instability evolution process of strongly weathered surrounding rock under effect of seepage. The results show that the surrounding rock of the shaft become significantly instable within 2-6 s, and the average moving velocity increases firstly and then decreases, peaking at 0.155 m/s; the fluid force acting on the shaft wall fluctuates sharply during 0-2 s and then gradually stabilizes. The shaft wall suffers large scale shallow abrasion, with a final wear area of 17.404 43 m2 and volume of 0.013 31 m3. Numerical simulation shows that the angle of repose for the collapsed shaft surrounding rock is 25°, presenting a relative error of only 1.88% compared to the on-site practical measurement, which has verified accuracy and practicability of such SPH-DEM method.
