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

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.
