Belt conveyor reduces truck traffic
A transportation corridor approximately nine kilometres long and 8.5 metres wide will be built to connect the mine and the concentration plant to transport ore. The route for the conveyor from the Hannukainen mine to the Rautuvaara concentration is part of the mining concession. The conveyor will start from an underground crusher at the mine in a 700-metre-long rock tunnel. The conveyor will be lifted higher to pass over Pakasaivontie, Sorakuopan tie, and a summer cottage road (Rautuojantie).
An underpass will be built for the conveyor at Ylläksentie and Äkäsjoentie. Passage ways under the conveyor will be built at Valkeajoki, Äkäsjoki, Rautuoja and two swamp
The conveyor will also be lifted higher for reindeer and forest machines on dry forest ground in Rautuvaara. The implementation and location of the underpasses has
been agreed on together with reindeer herders, Metsähallitus, and forest owners.
”The belt conveyor will be covered and protected by side walls to reduce dust emissions and noise.”
The conveyor is a new element, visible in the immediate landscape.The surroundings of the belt conveyor where most people move around, are the roads Ylläksentie and
Äkäsjoentie. At these locations, the conveyor goes under the roads, and is therefore not a particularly visible element in the landscape.
There will be road junctions built for the service roads of the conveyor, which will cause local modifications to the terrain. The highest points for the conveyor from the ground are the bridges crossing Pakasaivontie and Sorakuopantie. There, the maximum height of the bridge is 8.25 m. Lower road bridges cross other roads, rivers, swamps, and a reindeer area. The bridge crossing Äkäsjoki river has the greatest effect on how the landscape is perceived, because it is located close to holiday houses along the river and when the river is in recreational use. With the exception of tunnels and bridges, the conveyor follows the surface profile of the terrain.
A noise study has been conducted on the belt conveyor. Based on the modelling results, the average night-time noise levels of the belt conveyor and other mining activities
are, in holiday homes in the area under study, no more than 34 dB, and in permanent residences 26 dB, and thus below the night-time reference values.
In the conveyor area, the difference between the average noise levels during the day and night is very small (less than 1 dB), so the daytime reference values are also well below the accepted ones.
