深部围岩巷道支护技术

随着煤矿开采深度的逐年增加,传统支护方式已不能满足围岩巷道的支护需求,尤其在遇到不稳定的软岩的情况下,可以综合采用锚网喷支护、锚注加固、预应力锚索加固等方式。介绍了深部不稳定围岩巷道支护技术,工程实践表明,该技术应用于深部尤其是不稳定软岩巷道支护过程中,收到了良好的效果。

Deep Surrounding Rock Roadway Support Technology

With the depth of coal mining increased year by year,the traditional support approaches have failed to meet the needs of surrounding roadway,especially in the face of the case of instability soft rock,can integrate with shotcrete anchor,anchor grouting,prestressed anchor cable reinforcement and etc.Introduces the deep uncertainty surrounding roadway technology.Engineering practice shows that the technology applies to the deep especially instability soft rock roadway has receives good effect.
