注浆加固锚索联合支护在破碎围岩加固中的应用

Application of combined support of anchor cable and grouting in broken surrounding rock reinforcement

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 support 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 reinforcement.
