Blast safety door takes shape in Greymouth workshop as Pike River Mine re-entry looms

A Greymouth business which has a long history with Pike River Mine is responsible for making a blast door, a major safety component for the planned re-entry of the mine.

The blast door has been designed in Australia and is being manufactured by Gray Brothers Engineering.

Eddie Gray of the company told 1 NEWS  that if something goes wrong the door will drop and seal straight away.

The door will be fitted 15 metres inside the mine and can be operated from outside. 

Dinghy Pattinson of the Pike River Recovery Agency explained the door would be used if the mine had to be made inert.

"So if there's a fire or anything in your mine you have to be able to close those doors and put nitrogen in," he said. 

But it's a race against time.

Mr Gray said they received drawings for plates for the door on Monday and had Christchurch firm Vulcan Plate work through the night for them to be on a truck on Tuesday morning.

"I did say it was for Pike re-entry and we wanted to get it done as fast as possible. So they went the extra mile."

There are 104 steel components that make up the door and Gray Brothers are hoping to have it finished by the end of the month.

Gray Brothers Engineering made many of the original components for the mine.

"We've done work at the mine from day one," Mr Gray said.

So this isn't just any job.

"I think it's in every West Coaster's heart to get closure for the families. It's pretty close to everyone on the Coast, we've all got friends and families that were involved in it," he said. 

And the Gray Brothers team say they'll feel proud when their door is installed in the mine next month.
