New open-cast mine at Gruvberget, Svappavaara

Hydrogeological surveys before the opening of a new open-cast mine at Gruvberget in Svappavaara.

LKAB has opened a new open-cast mine at Gruvberget in Svappavaara. Before operations started up, ÅF conducted hydrogeological surveys in order to assess how the surrounding area would be affected by the new open-cast mine.

The hydrogeological survey included an analysis of, among other things, the impact on individual wells, lakes and vegetation. The survey also included a forecast of the volumes of water that will need to be pumped away in order to dewater the open-cast mine at different levels of extraction.

ÅF’s assignment at Gruvberget included the following elements:

  • Hydrogeological survey including drilling and test pumping
  • Assessment of impact on the surrounding area
  • Technical expert in main negotiation for environmental permit
  • Production of base data for dimensioning of pumping plant
  • Design and cost assessment of facility for drawdown of groundwater
  • Production of draft control programme for mining operations
