| 摘 要： | 本文通过理论分析、相似材料模拟试验、现场实测，总结出巷道围岩失稳的临界深度与围岩性质及支护方式有关，围岩强度越高，失稳的临界深度越大；主动支扩大于被动支护的巷道围岩失稳的临界深度。这些结论对于深部开采巷道布置、支护方式的选择具有重要意义。

| Abstract: | By means of theoretical analysis,simulation model experiment with equivalent materi-al and tbe observation at worksites,this paper sums up that the critical depth of surrounding rock losing stability of roadway i s related to rockstrata property around roadway and supporting types. The more the surrounding rock strength of roadway is,the more critical depth of sur-rounding rock losing stability of roadway i. The critical depth of surrounding rock losing stabili-ty of activly supporting roadway is more than that of passivly supporting roadway. These conclu-sions play an important role in arranging the places of roadway in deep mining and choosing supporting:type. |
