摘 要:针对亭南煤矿回风大巷围岩松软破碎、巷道底鼓严重等问题,提出了“锚索+高压注浆组合式”巷道软岩底板加固技术。根据回风大巷变形破坏特点,对巷道底板的锚索注浆加固方案和注浆工艺进行了设计,并在回风大巷进行了工程实际应用。实践表明,加固后的回风大巷满足了安全生产需要,技术经济效果良好。In view of the problems of soft and broken surrounding rock and severe bottom heave in the return air main roadway of Tingnan Coal Mine,a"anchor cable+high-pressure grouting combination"roadway soft rock floor reinforcement technology is proposed.According to the deformation and failure characteristics of the return air main roadway,the anchor cable grouting reinforcement scheme and grouting process for the roadway floor are designed and applied in engineering practice in the return air main roadway.The practice shows that the reinforced return air main roadway meets the needs of safety production and has good technical and economic effects.
