摘　　要：本论文基于分层崩落法对地下矿山开采过程中矿体与围岩的稳定性进行了分析。通过对某地下矿山的具体工程实例,综合应用地质力学、数值模拟及现场监测等多种手段评估了矿体和围岩在开采过程中可能出现的变形与破坏机制。研究表明分层崩落法在保持矿体稳定性和围岩控制方面具有显著效果,但需要针对不同地质条件进行优化设计。本文的研究成果可为类似矿山的安全高效开采提供理论支持和实践指导。This paper analyzes the stability of the ore body and surrounding rock during the underground mining process based on the layered collapse method.Through a specific engineering example of an underground mine,various methods such as geomechanics,numerical simulation,and on-site monitoring were comprehensively applied to evaluate the possible deformation and failure mechanisms of the ore body and surrounding rock during the mining process.Research has shown that the layered collapse method has significant effects in maintaining the stability of the ore body and controlling the surrounding rock,but optimization design is needed for different geological conditions.The research results of this article can provide theoretical support and practical guidance for safe and efficient mining in similar mines.
