摘要
通过对许疃煤矿82下人行下山二区段北翼岩石集中回风联巷的施工技术难题进行研究,结合现场实际情况,提出了合理的联合支护方案,永久支护和补强支护相互作用,经现场实践证明,该项支护技术能够有效地控制围岩在应力集中区的变形和破坏,确保了巷道的安全施工和后期的有效利用,满足安全生产要求。
Through the research to technical problems of Construction on the section 2, north rock airreturn roadway of the 8-2 - down men- dip entry of Xutuan Coal Mine and according to the scene of the actual situation, the paper provided a reasonable program of Combined Support which Permanent support interact with supplement support. It has been proved by practise that this Support Technology can effectively control the surrounding rock＇ s deformation and ruin in the zone of Stress concentration. It ensures the safety of roadway construction and the latter effective use, and Meets the requirements of Production safety.
