A Closer Look

The Bedrock Fracturing (KYT KARIKKO) project

• The KARIKKO project jointly funded through the Finnish Research Programme on Nuclear Waste Management (KYT) studies the safety of nuclear waste disposal.
• The project focuses on the scalability of brittle bedrock structures, i.e. fractures and faults.
• The project’s goal is to assess the properties and quality of fracturing at different scales in Southern Finland, using large-scale lineament interpretations based on geophysical and topographic datasets.
• The project focuses especially on method development and data production.

The Bedrock Fracturing – Solutions for Customers project

• The self-financed project supports competence development and focuses on the interfaces of structural geology, hydrogeology and geothermal research.
• The project studies the relationship between the fracture network and hydrogeological properties with estimating water flows in bedrock and verifying hydrogeological models. As water flows in bedrock through fractures, it is important to understand what fracturing is like, and which fractures enable water to flow. The goal is to identify how this can be modelled further.
Stability studies assess rock cuttings and their safety. Any areas where rock can fall from cuttings involve specifically high risks, e.g. at roads and railroads. The study also develops a code for a stability assessment tool.
• Studies have also been conducted in an open-pit mine environment. A drone was used to take images of an open-pit mine, and the images were processed based on photogrammetry. As a result, point cloud and 3D data, including 3D fracture orientations, were produced. Development helps understand stability in environments similar to open-pit mines and locate bedrock edges where the collapse risk is probable. The work has only begun, but good results have already been achieved.
