BRIGHT IDEAS Innovative technology that can help minimise the impact of power failures in mines
these utilities caused by power failure can aff ect the entire mining operation. By developing a take-up winch equipped with an innovative braking control system, Svendborg Brakes has ensured unprecedented conveyor effi ciency and reliability, which in turn improved the productivity of a copper mine in Chile. Mining is among the most challenging industries as work is often conducted in remote locations and under unstable
C
onveyor take-up winches are essential components for the mining industry. T erefore, any malfunction or sudden stop of
conditions. In particular, power supplies in mines are a primary concern. Even though they have greatly improved over the years, power failures are still quite common. T ese can heavily aff ect a mine by forcing the company to suspend operations and by causing damage to any equipment that abruptly stops during power outages. One of the most important pieces of the mining equipment is the belt conveyor, which transports minerals around the mining site. Tension in a conveyor’s belt is fundamental to its operation, as it enables the support of the load between rollers as well as the drive
to move the conveyor’s belt. T erefore, the conveyors are often equipped with systems such as take-up winches that adjust and maintain the conveyor belt’s tension during operation. During power failures, all equipment suddenly comes to a halt, which can cause considerable stress to equipment that is under load. In fact, even ‘smart’ winches, that promptly react to any changes in tension, are not operational during power outages, and these will also contribute to the equipment stress. If this stress is not mitigated, multiple pieces of equipment on the conveyor can be damaged.
