“复杂地层高应力、碎胀泥化”围岩下的组合圈体梁支护技术

Supporting Technology of Composite Ring Beam under Surrounding Rock of "High Stress, Broken Expansion and Mud in Complex Stratum"

采用多喷层混凝土、高强锚杆、注浆锚杆、钢丝绳有机组合形成的柔性封层,施以稳压注浆高强胶结岩煤体,将周边围岩构建成组合圈体梁,强化围岩整体承载能力,有效抵御复杂地层、碎胀泥化状态下的软岩巷道复杂应力,保证软岩巷道的长期稳定。

The flexible seals formed by multi-shotcrete, high-strength bolt, grouting bolt and wire rope were applied to stabilize grouting high-strength cemented rock coal body, and the surrounding rock is constructed into a composite ring beam to strengthen the overall bearing capacity of surrounding rock and effectively resist the complex stress in soft rock roadway under the condition of complex stratum and fragmentation and mud,which has ensured long-term stability of soft rock roadway.
