End Of The Project
As they continued to drill deeper into the Earth, the Russian team began to anticipate its completion. Neither the high temperature nor the plastic-like rocks would allow their equipment to last for very long. They worked on it until 1992, but they couldn’t make any further progress. Because of this, they were forced to halt drilling operations. In 2005, the drill site and the Kola superdeep borehole were officially closed. However, just because work stopped on the project doesn’t mean it was useless.
Kola Superdeep Borehole
Before capping off the borehole, which they named the Kola Superdeep Borehole, the research team uncovered some fascinating results. The data collected from the Kola Superdeep Borehole is invaluable to the study of geology. The Russian team may not have made it to the mantle, but they did succeed in digging the deepest hole ever. Plus, the data they uncovered was extremely useful to scientists generally.
