摘　　要：为提高采面回采巷道超前支护效率,基于山西某矿3703回风巷现场实际情况,提出采用锚注技术进行超前支护。针对3703回风巷使用锚注技术超前支护可行性进行分析并给出具体支护方案。现场应用后,采面回采前进锚注技术超前支护段顶板始终保持稳定,未出现失稳迹象,同时最大下沉量为35 mm。研究成果可为其他矿井类似情况下回采巷道超前支护提供经验借鉴。In order to improve the efficiency of over-supporting of the mining face back to the mining lane, anchor injection technology is proposed to be used for over-supporting based on the actual situation of 3703 backwind lane.The feasibility of using anchor injection technology for over-supporting 3703 backwind tunnel is analyzed and a specific support plan is given. The research results can be used as a reference for other mines in similar situations.
