深井高地压巷道锚杆支护技术研究

On the Bolt Supporting Technology for Deep High-Geopressure Roadways

对于煤矿开采而言,巷道深度越深,其作业环境就越复杂,危险系数就越高,这无疑加大了对围岩变形的控制难度,特别是深井高地压巷道,因其有着更为特殊的岩体力学和结构特性,致使普通支护难以奏效,故经不断创新的锚杆支护为解决上述难题带来了机遇。对此,从深井高地压巷道出发,就锚杆支护技术及其应用进行了研究,以期增强巷道支护效果。

For coat mining, the deeper the roadway is, the more complex its operating environment is, and the higher the danger coefficient is, which undoubtedly increases the difficulty in controlling the deformation of surrounding rock, especially the deep high-geopressure roadway, for which the general support is ineffective because of its more special rock mechanics and structural characteristics, so the innovative bolt supporting brings opportunities to solve these difficulties. In this regard, based on the high- geopressure roadway, the bolt supporting technology and its application are studied in order to enhance the supporting effect of roadways.
