| 中文摘要:空气以反循环取样钻进技术是国外目前比较成熟与先进的工艺，但国内运用相对较局限。本文结合近年来的研究，尤以2015年在云南省腾冲小龙河锡多金属矿区与岩心钻探进行了对比试验，主要对地层、矿（化）体是否丢失情况、施工效率等进行研究。研究表明，空气反循环取样钻探，在地质找矿中，具有施工效率高、生产成本低、找矿效果好的优点，同时也发现了该工艺在地质找矿中的局限性以及需要进一步研究的问题。 |

| Abstract:Air reverse circulation drilling technology is a mature and advanced process abroad, but is relatively limited in China. Based on the research in recent years, especially a contract test between air reverse circulation drilling and core drilling was carried out in Xiaolonghe tin polymetallic deposit of Yunan Tengchong in 2015, the formation, mineralization bodies loss and construction efficiency were studied. The research shows that air reverse circulation sampling drilling has the advantages of efficient construction, low cost and good in geological prospecting. Meanwhile, the limitations of this technology in geological prospecting and some problems that need further study are also found out. |
