许多金属矿山存在采空区群安全隐患。基于CMS对某矿山的采空区群开展定期探测，形成动态监测机制，精确获取采空区群三维边界；研究构建空区群连锁式失稳模型：基于突变理论分析方法，构建了采空区顶板-隔离矿柱力学模型，提出隔离矿柱失稳的判据，计算合理的隔离矿柱安全厚度，阻断空区群连锁失稳过程。运用数值模拟验证了计算结果的合理性。研究表明通过精确控制隔离矿柱的安全厚度，可有效阻断空区群连锁失稳导致的工程灾害；计算结果为下一步资源回采方案提供了设计参考。

There exists security risks of goaf group in many metal mines. Regular detection on mine goaf group was car-ried out based on CMS,forming a dynamic monitoring system and accurately obtaining goaf 3D boundary. The chain instability model of isolate pillars was constructed:the mechanics model of the roof-isolate pillar of goaf was put forward based on catastro-phe theory,and the instability criterion of isolate pillar was proposed,to determine the reasonable safety thickness of isolate pil-lar and prevent from the chain instability of goaf group. The numerical simulation verified the rationality of the calculation. In the research,through accurately controlling the safety thickness of isolate pillars,the disaster induced by goaf group instability can be effectively avoided. The results provide reference for the design of mining scheme.
