6) m2 openings or tight shotcrete walls in front of ivn2 and pn have been installed down to the level of +590 m with pn and to the level of +610 m with ivn2. (Martikainen 2002) The choice between a tight wall and a wall with an opening was made based on the ventilation demand on the level at the time of decision-making. Flexible ventilation ducts are used to direct the air to the production areas from ventilation walls with openings. The ducts have diameters of 1000 mm in main tunnels and 800 mm in drifts.

The mining height of the large project reaches from level +202 m down to level +525 m. An old ventilation model made with the Ventsim program in 2002 was used as a basis for planning. This was then supplemented with preliminary Sarvisuo mining plans. Different ventilation alternatives with either one or two new shafts were finally tested to model the ventilation. Orivesi gold mine is located in southern Finland, about 220 km north of Helsinki. The mine site belongs to the early Proterozoic Tampere schist belt located in the central part of the Svecofennian domain.
