Tapuli Mine Pre-Development: Dike Construction and Dewatering of the Starter Pit

Abstract [en]

On December 20th, 2010, Northland Resources AB was approved to begin mining iron in the ore body Tapuli, located in Kaunisvaara, north of Pajala. This was the start of a huge project that will last for decades and employ hundreds of people, both locals and settlers.However, it is not as simple as just to start mining the ore, pre-development work must be performed to access this valuable resource. The Tapuli ore body is located below a swampland consisting of a layer of peat with an average thickness of 3 m overlaying a layer of glacial till with an average thickness of nine meters. The water content of the peat has an average of about 700 % and the bearing capacity is so low, that no heavier machines can run on the peat.This master thesis is a case study dealing with pre-development work of the starter-pit in Tapuli. The work deals with the construction of the dike around the starter-pit and dewatering of the area inside the dike. A literature study has been done to gather background information of the area. Study visits and interviews have been carried out at companies with people who possess experience from similar work to get information about their thoughts. The work on site in Kaunisvaara have been documented and analyzed and a discussion has been done in which conclusions and recommendations for future work with similar circumstances have been presented.
