| Abstract |
The UCPH shallow drill is intended as a fast drill, operating to depths between 25 and 100 m. A 25 m core can be retrieved in 4 hours, and a 100 m core in one day. The maximum obtained depth is 325 m, with a decreased drilling time for depths higher than 100 m. At depths deeper than some 130 m the core fractures. The core quality was improved at depths below 200 m, by applying a smaller pitch. This created fine chips which enhanced the risk for the drill to get stuck. |
