摘　　要：松动圈是围岩收敛变形的主要原因,其厚度既包括影响围岩稳定性的诸多因素,又反映出诸多因素的相互作用结果,是一个综合性的分类指标。以松动圈分类结果为依据的巷道支护设计,理论基础较坚实,现场运用效果显著。The broken rock zone is the main reason of convergent deformation of surrounding rock, its thickness includes the factors affecting the surrounding rock stability, reflects the result of many factors interacting on each other, it is a comprehensive classification index. The design of roadway support based on broken rock zone classification results, has solid theoretical foundation and remarkable effect in field application.
