ABOUT 30 miners were forced into rescue chambers when an underground fire broke out in the Fosterville Gold Mine.Two men experienced smoke inhalation during the fire which broke out about 450 metres underground in the mine about 2pm Saturday.Authorities believe an underground loader’s hydraulic line burst and started the fire.Fosterville Gold Mine general manager Ian Holland said the incident triggered the site’s emergency response procedures.“It is a crucial piece of equipment and all these types of machines have automatic fire suppression,” he said.“That has been triggered but there was still smoke that came out. Two of our underground crew (were) exposed to some smoke inhalation.“We triggered our emergency response plan and everyone else underground in the mine went into rescue chambers.”An Ambulance Victoria spokesman said paramedics treated the two men for smoke inhalation at ground level.He said neither men needed further treatment nor hospitalisation.About 26 miners remained in the rescue chambers until the smoke had cleared.Mr Holland said night-shift workers started their shifts without delay. He said he was pleased with the organisation’s emergency response to the fire.“It is fair to say it is why we do our mock emergencies and why we work with other agencies,” Mr Holland said.“We have a mine rescue team and we have our own fire fighting facilities – we have our own truck and everything is fitted with fire extinguishers.“We dealt with it internally and other agencies responded and they were there to provide additional support.”Mr Holland said the organisation was investigating the incident and would implement any needed modifications.Country Fire Authority regional duty officer Rohan Luke praised Fosterville’s emergency procedures.“It’s an example of agencies and mining companies working well together,” he said.
