MINE VENTILATION
ventilation systems capable of providing advice and the necessary technical support to clients , increasing the level of safety and profitability of projects by optimising energy use , the companies said . It started operations in Santiago , Chile , with a production plant of more than 2,000 sq . m and will be present in Latin America directly through entities in the region and an exclusive distributor in Colombia .
“ We are confident that this new company will allow us to deliver more efficient and comprehensive solutions to our customers and will enable us to continue to reinforce progress in underground mining and tunnelling ,” the companies said .
NYB offers several mechanical sensors to gauge vibration , temperature , and speed of motor , bearings and drives
operate at increased depths .
“ Given the stress on fans over time , wear is inevitable and can be properly managed using monitoring devices to avoid unplanned downtime and maximise productivity and output ,” NYB says .
Material build-up from heavy dust loads , corrosion caused by excess moisture , and other harsh conditions can all result in decreased fan efficiency . Overcoming deficiencies causes the motor in these fans to work harder , leading to excessive energy consumption and increased energy costs – and potential safety hazards when motors operate outside their safe range . Repetitive or unexpected maintenance also increases costs and results in lost production time .
Fan sensors , however , give users greater visibility into the performance of their equipment to help predict and prevent mechanical failures while optimising operational efficiency , according to NYB .
“ The difference in being proactive to potential maintenance problems can result in significant long-term cost savings ,” the company says .
NYB offers several mechanical sensors to gauge vibration , temperature , and speed of motor , bearings and drives . When the devices detect changes above a certain threshold , they send automatic alerts or can make preemptive changes if programmed to do so . The amount of dirt and dust in the airstream and moisture content can also be monitored and air flow can be adjusted automatically .
By continuously monitoring power input , meanwhile , artificial intelligence-powered software can adjust for optimal power usage .
The initial cost of purchasing and installing these fan sensors is quickly recovered with the multitude of benefits they provide , NYB argues .
“ By presenting immediate insight into equipment performance , remote monitoring enables users to measure and improve overall equipment effectiveness ,” it said . “ Some benefits include trend tracking over time to improve and increase reliability , reduced maintenance costs for replacement parts and personnel , and optimised power consumption .”
This all plays into the growing trend of VoD to maximise energy efficiency , increase safety for mine workers , and reduce operating costs , NYB says .
Collaborating on safety
DSI Underground , now owned by Sandvik Mining and Rock Solutions , signed a joint venture agreement with ABC Canada in 2020 to create DSI Underground Ventilation Systems .
The product portfolio of the new joint venture includes Flexline™ and semi-rigid Hardline™ flexible vents for positive and negative airflow , high-efficiency Toughvent fans and other ventilation accessories – curtains and coverings , emergency shelters , inflatable airstop and repair kits .
DSI Underground Ventilation Systems has a team of engineers specialising in the design of
Intelligent Ventilation Management Systems for the Mining Industry
CFH takes on 100 % of Korfmann
Germany-based CFH GmbH , a supplier of ventilation , cooling / heating , methane drainage and dedusting solutions to the mining industry , recently took over Korfmann Lufttechnik GmbH .
The 100 % owner of Compact Filter Technic ( CFT ) technology , its systems are used in all types of mining , with de-dusting , ventilation , air heating and cooling , and methane drainage all key CFT competences .
Since 2001 , all Korfmann fans and silencers have been manufactured exclusively by CFT , with nearly 6,000 Korfmann fans successfully designed and delivered for mining and tunnelling applications worldwide .
In recent years , CFT and Korfmann have successfully implemented ventilation projects for main mine fans with impeller diameters up to 3.35 m . The CFT portfolio also includes numerous successfully completed projects for air heating and cooling systems in mining . These range from single heating or cooling units with a capacity of up to 3 MW each , or complete systems with capacities exceeding 30 MW . IM
