摘  要:随着云南省北衙金矿服务年限和开采深度的增加,万硐山露天采场边坡稳定问题显得尤为重要。本文从内因和外因两个方面总结分析边坡稳定性的影响因素,其中地质构造和水是主要的影响因素。提出合理规范开采、确保排水疏干、加强监测预警、优化爆破方法及参数、坡面防护等防治建议,为露天采场境界优化、边坡治理、矿山安全开采提供地质依据。With the increasing service life and mining depth of theBeiya Gold deposit in Yunnan Province,the stability issue of the slopes at the Wantongshan open-pit mining site have become particularly important.In this paper,the factors affecting slope stability from both internal and external aspectswere summarized and analyzed,among which geological structure and water are the main influencing factors.Recommendations for controlling and preventing slope instability wereput forward,including reasonable and standardized mining,ensuring drainage and dewatering,enhancing monitoring and early warning,optimizing blasting methods and parameters,and implementing slope protection.These suggestions provide a geological basis for optimizing the open-pit mining boundaries,slope management,and safe mining.
