摘要
本文针对一些巷道在动压及其它因素的影响下发生多次严重破坏的现象，分析了巷道的破坏原因，讨论了现有支护形式的特点，确定了选择此类巷道合理支护方式的原则，提出了３种基于锚注支护的联合支护结构，并在工程施工中得以应用。
The article mainly analyses the cause of roadway's damage according to the phenomenon that some roadways have been seriously damaged many times under the effect of dynamic pressure and other factors,discusses the feature of all supporting methods in existence ,determines the principals for selecting rational supporting patterns for these kinds of the roadways and suggests three kinds of joint supporting structures based on the roof bolting and grouting ,at last,the methods have been used in some engineering examples.
