Howden says it has secured a contract for the upgrade of an existent licence of its Ventsim™ CONTROL ventilation system at the Agnico Eagle-owned Fosterville Gold Mine in Victoria, Australia.
The initial installation of Ventsim CONTROL Level 3 (scheduling and flow control) has already greatly improved the operability and flexibility of the ventilation system, as well as providing efficiency to pay for itself in just six months, Howden claims. Now, in a first for the Australian mining sector, the mine tracking system will be integrated to Ventsim CONTROL Level 4. This will provide real-time feedback on the vehicle locations in Ventsim CONTROL to adjust the ventilation automatically based on demand.
Camille Levy, President of the Asia Pacific Region at Howden, said: “This next stage contract for Fosterville mine is significant for Australian mining and the Howden Ventsim team as it represents the first Ventsim CONTROL Level 4 system that has been commissioned remotely as well as a first in APAC. The success of the operation and the level of power it saves serve as a test case for further installations of Ventsim CONTROL globally. The fact that the system paid for itself within six months is impressive.
“As the system allows the mine to optimise its ventilation based on fully remote vehicle and personnel monitoring, it directly contributes to Australia’s 2030 emissions reduction targets – something of which the Howden team is very proud.”
Level 4 – Ventilation on Demand (VoD) is the process of adjusting mine air flow in real time based on vehicle and personnel position. Ventsim CONTROL provides an ‘on demand’ solution for mine ventilation. Software connected to hardware devices remotely monitors, controls and automates airflow. The technology provides safer ventilation that is more productive and cost effective, according to the company. The Ventsim CONTROL solution also offers a 3D modelling capability within the software, which helps users to better predict and control air flows based on what is evidenced in the simulation.
Howden recently announced its target to be carbon net zero by 2035 through the purchase of renewable energy and carbon-free energy; efficiency gains from energy conservation measures; and by renewable energy projects at its manufacturing facilities. The largest impact the business will have on global sustainability will be through its partnership with customers to supply equipment that will make a major impact on their carbon emissions and sustainability, it says.
In 2020, Fosterville produced a record 640,467 oz of gold at an average grade of 33.9 g/t Au and average recoveries of 98.9%.
