大口径矿山抢险救援快速钻进技术

Fast Drilling Technology of Large Diameter Well for Emergency Rescue in Mine

摘要:

随着国家对矿山安全生产工作的高度重视，矿山应急救援钻井装备与施工技术迅速发展。快速钻进技术与工艺是提升矿山垂直钻进应急救援技术水平的关键。针对矿山救援所遇地层复杂，意外因素多，尤其在抢救被困人员过程中，施工所需时间长等问题，从抢险救援装备选择与工艺配套方面进行了讨论，对实现快速钻进紧急救援，降低事故伤亡率、减少经济损失，具有重要的意义。

Abstract:

Because of the high attention to mine safety production work in China, mine emergency rescue drilling equipments and construction technologies are rapidly developed. Fast drilling technology and process is the key to improve the level of emergency rescue technology of vertical drilling. In the cases of complex formations and unexpected factors, and especially in the long period of time to rescue the trapped workers, it is necessary to consider the rescue equipments selection and process matching, which have important significance to realize the emergency rescue by fast drilling and reduce the accident casualty rate and economic loss.
