深井软岩巷道底板加固技术研究与应用

摘要

在传统的软岩巷道底板加固技术的基础上，采用注浆加固与预应力全长锚索锚固及U型钢反拱联合支护的巷道加固技术，治理软岩巷道底板反复变形，探索深井软岩巷道底板注浆加固与反拱联合支护技术的特点。%Based on the traditional soft rock roadway floor reinforcement technology, using the grouting reinforcement and prestressed anchor cable and U type steel anti arch combined supporting technology to manage the soft rock roadway deformation, and explore the characteristics of the lfoor grouting reinforcement and anti arch combined supporting technology in deep soft rock roadway.
