Chilean Mine Rescue
October 9, 2010 (The San Jose mine in Copiapo, Chile) – The Center Rock drill being used to reach trapped miners more than 2,000 feet underground, often referred to as “Plan B” by the media, has broken through the miners today, far ahead of the earlier projections that drilling might take until Christmas.
Replacing the Harrison Avenue Bridge
The Harrison Avenue Bridge in Scranton PA, which was built in 1922 and has outlived its usefulness.
The objective was to replace the Harrison Avenue Bridge in Scranton, Pennsylvania, which was built in 1922 and had outlived its usefulness. 3C Drilling, LLC was contracted to drill (7) 96” diameter piers ranging in depth from 35’-55’ deep. (10’-12’ overburden and 43’-45’ rock) One pier was for a test pile and then (3) piers on each side of Roaring Brook and Central Scranton Expressway.
Five years ago, Center Rock Inc., was contacted by Malcolm Drilling due to low production with conventional rock augers and core buckets on a job site for the Highway 56 and 15 Connector in San Diego, CA. Center Rock sprang into action and manufactured a series of tools ranging in size from 48 to 96 inches for this project.
For many years, Center Rock Inc. has been the leader in the manufacture and application of the multi-hammer canister drill (LP Drill). From its use in the 2010 Chilean Mine Rescue, when 33 miners were rescued through the 26” (66cm) hole drilled by a Center Rock LP, to horizontal push-pull applications, the Center Rock LP drills in any inclination from vertical to horizontal for mine rescue, burn holes, utility and ventilation shafts.
