Atlas Copco Boomer XE3 C drilling rig opens a new chapter of tunnel construction in Taiwan
Founded in 1945, Continental Engineering Corporation is one of the leading engineering and construction companies in Taiwan and has played an important role in the engineering history of Taiwan. Since establishment, it has been involved in construction projects throughout Taiwan and the world. To improve drilling precision and productivity, the company purchased an Atlas Copco Boomer XE3 C three-boom drilling rig equipped with computerized Rig Control System (RCS) in February 2015 and successfully deployed it in Renshui Tunnel Project (Section C2, Su-Hua Highway, Taiwan Highway No. 9), blazing a new trail in tunnel construction using a modern computerized rock drilling jumbo.
Automatic control to solve tough challenges
Endeavoring to minimize downtime and enhance borehole quality and efficiency, Continental Engineering Corporation thoroughly researched similar products available on the market, and selected Boomer XE3 C three-boom drilling rig equipped with RCS. RCS can help rig operators monitor and control drilling parameters, and records rig operating status, events and errors for follow-up analysis. After operating the system for a while, Mr. Lin commented, “RCS improves drilling precision and stability as well as reduces the time needed for training new operators. It gave us strong support in meeting the challenges involved in the Renshui Tunnel Project.”
Outstanding efficiency and drill durability
Continental Engineering Corporation equipped Boomer XE3 C with original drills produced by Atlas Copco to achieve maximum production speed and efficiency， and can really sense the important role of grinding in ensuring extended drill durability. After being ground 2-3 times by an Atlas Copco Secoroc BQ3 grinding machine, the average service life of a drill bit can be prolonged by 30% to ~700m.
Intimate service for a successful model
Vincent Chou, Atlas Copco’s on-site service engineer, best qualified to speak on this matter, said: “We stand by 24/7 to serve the client as and when needed. Since Boomer XE3 C is the first computerized drilling rig purchased by Continental Engineering Corporation, the operators lacked experience. We offered training to them in groups on how to master the equipment as quickly as possible. Additionally, I was involved in checks and maintenance service on the rigs myself at least once every day, each session lasting 2-4 hours.” Chou said that even when the rigs are in normal operation, he stays at the site watching through drilling operations, so that any potential issues leading to breakdowns could be identified and solved within the shortest time possible.
As the old Chinese saying goes, “if you put your heart to it, you can break up metal and rocks.” With hard work, the Atlas Copco Boomer XE3 C Drilling Rig made a good start in the Renshui Tunnel Project at Section C2 Su-Hua Highway (Taiwan Highway No. 9). More importantly, this is a landmark in the use of modern computerized rock drilling rigs in tunnel construction in Taiwan.
