摘　　要：大口径地面钻孔救援技术多次在矿难救援中得到成功应用。但由于地层的复杂性、装备及工艺适配性不足等各方面的限制,影响了地面钻孔救援的施工效率。本文以矿难大口径地面钻孔救援装备和大口径钻孔快速钻进技术为主线,分析了目前地面钻孔救援技术存在的主要问题,并针对性地提出了应对措施,包括研发双动力头钻机、跟管钻进技术、高效套管焊接技术、潜孔锤钻进技术以及反循环钻进技术等,以期为今后矿难大口径地面钻孔救援施工技术及装备研发提供建议与技术基础,进一步提升钻孔救援的施工效率,加速构建科学的矿难救援体系。In recent years,the large‑diameter borehole rescue technology has been successfully applied in mine disaster rescue for many times.However,the construction efficiency of drilling rescue is affected by the complexity of stratum,the lack of equipment and process adaptation.This paper takes large‑diameter borehole rescue equipment and large‑diameter rapid drilling technology as the main line,sorts out the main problems existing in borehole rescue technology at present,and puts forward corresponding countermeasures.Including the research and development of dual power head drilling rig,drilling with casing technology,high‑efficiency casing welding technology,down‑the‑hole hammer drilling technology and reverse circulation drilling technology,etc.Hoping to provide sugestions and technical foundation for large‑diameter borehole rescue and further improve the construction efficiency of borehole rescue and accelerate the construction of scientific mine rescue system.
