Application of Hydraulic Internal Cutter and Retrievable Spear for Drill Rod Fishing in Deep Hole
Abstract:The drill sliding accident was handled by drill rod section-cutting with hydraulic cutters and fishing with retrievable spear in 47ZK3 of Luanjiahe gold mine in Zhaoyuan of Shandong. With the engineering case, the paper introduces the usage of hydraulic-pressure cutters and retrievable fishing spear, and presents the comparison between this and conventional fishing by reverse-thread drill rod and screwing fishing.
