Competence development for mine backfilling technologies (KOVE-PRO)
Competence development for mine backfilling technologies (KOVE PRO) -project studies the stabilization and utilization of mine tailings as Cemented paste backfill (CPB) material in underground mine facilities. CPB is a method of reducing the overall environmental impacts of mining.
The project is implemented by Savonia University of Applied Sciences, GTK and business partners. The reduction and replacement of the cement with secondary raw materials is studied in order to find the most economical and environmental friendly backfilling recipes. The environmental suitability and durability of these new backfill materials are tested in simulated mine conditions. In addition, dewatering and pumping methods of the paste are developed during the project.
