Temporary Shutdown Of GAG At Pike River Mine
The Gorniczy Agregat Gasniczy inertisation machine (GAG) is currently shut down at the Pike River mine to allow two high
pressure hoses to be replaced.
The specialist hoses supply water to the machine and were found to be damaged yesterday.
New fittings were manufactured in Christchurch last night so the replacement hoses could be attached to the GAG.
This required the old fittings to be sent to Christchurch so engineers could make an exact copy for the Polish designed
machine.
The new hoses and fittings were trucked back to the mine overnight from Christchurch because the load dimensions and
weight meant they could not be airlifted.
The machine is expected to resume operation later today and the shutdown has provided the opportunity for extensive
maintenance to be carried out.
"This is a complex, powerful device involving a jet engine and high pressure water. It has been running since Wednesday
night" said Superintendent Gary Knowles.
"You can't pick up spares at the local hardware store and it's unrealistic to have a spare for every possible part on
site."
"The shut down is not helpful but we are advised by our experts that it is unlikely to have a significant impact on
efforts to extinguish the fire."
