注浆加固锚索联合支护在破碎围岩加固中的应用

摘要

结合现场围岩条件，宝欣煤业回风大巷加固工程巷道底板采用水泥基无机注浆材料为主，帮顶采用高分子化学浆，配合高强锚索加固。实际工程中应用表明，锚索支护与注浆加固技术的正确应用，对变形巷道加固治理效果明显。%Combined with the surrounding rock conditions of main return roadway in Baoxin Coal Mine , the combined sup-port that the cement base inorganic grouting material is mainly used in roadway floor , macromolecule chemical slurry is used in roadway rib and roof and anchor cable is reinforced , was proposed .The practical engineering application shows that the anchor cable support and grouting reinforcement technology can achieved good effect in broken surrounding rock roadway re -inforcement .
