高应力煤矿巷道变形特征及支护策略研究

Study on high stress roadway deformation features and support measures

本文以常村煤矿轨道斜巷变形破坏特征为研究对象,分析导致轨道斜巷出现大范围变形破坏的主要原因是高地应力、围岩岩性相对较弱、地下水等因素。针对深部巷道变形破坏的特点,提出了恒阻大变形锚杆+锚网喷耦合支护方案,通过现场应用观测,设计的支护方式较好实现了对轨道斜巷围岩变形的有效控制。

Deformation and failure characteristics of coal mine track inclined roadway of Changcun Mine was taken as study object,the main reason was concluded as high ground stress,relatively weak surrounding rock,groundwater,etc..Based on characteristics of deep roadway deformation and failure,constant resistance,large deformation bolt and coupled support of anchor net shotcrete plan was put forward,the support enabled to control surrounding rock deformation of inclined roadway.
