What our clients have to say
Mine Ventilation Engineer
LKAB Kiruna (the world's largest underground iron mine)
We appreciate the cooperation we are having with EOL Ventsystem. They have been providing us with excellent help with various ventilation solutions, where everything from flow paths and air calculations to complete fan installations are handled. Our experience so far is an appreciated and personal ongoing dialogue, as well as products we now have several years of good experience from.
CASE STUDIES
The Pyhäsalmi Mine: How switching to modern fans drastically decreased energy costs
The Pyhäsalmi Mine is a 1 400 meter deep underground zinc and copper mine, located in central Finland and owned by the well-known Canadian mining company First Quantum Minerals Ltd. In 2014, EOL Ventsystem was invited to see if we could find- and suggest any potential improvements around the already well-working ventilation solution, and, if possible, lower their current energy expenses.
Their primary ventilation system consisted of one large, axial, fresh air fan as well as three exhaust air fan stations, each one with smaller axial-fans. The total installed fan power of the primary exhaust system was 748 kW.
After measuring the primary fans duty point in the mine and running exact simulations of the air flow in the mine, we had a radical proposal to give them: If they were to replace two of the three exhaust air fan stations completely with more modern, high-efficiency fans, they could remove the third fan station completely, and still have a top-quality ventilation system at a fraction of the current cost. This third fan station had 6pc 55kW fans.
After seeing the numbers, they chose to follow our improvement suggestions, with the result that The Pyhäsalmi Mine now saves about 1 500 000 kWh in energy per year. These energy savings are big enough that the investment cost itself - two completely new high-efficiency fans - was covered within approximately six months.
