A miner issue

[FJRider]

I would have thought the methane would be vented through ventilation shafts or extracted using a normal extraction fan and ducting type system. I wouldn't have thought it would use a system capable of pumping 800 litres per second back into the mine.

You mean ventilation SHAFT (singular) ...

As the mine was on DOC controlled land (or at least under it ... only one ventilation shaft was allowed to be sunk ...

DOC?
The Dept of......Overly Cautious?

Also if there is a fire in the coal seam it may not go out (http://en.wikipedia.org/wiki/Centralia,_Pennsylvania)

The Kamo Coal Mine fire up in Whangarei was going for years after it started, causing that mine to close. Coal makes every hot fires with a bit of air flowing thought it. Will melt steel easily at 1000deg C+. By the way Carbon can be ignited by Purer O2 or highly compressed air,

No ... as I understand it, just more of the "unspoilt" native forest would be damaged if more shafts were put in. It was one of the conditions they were given, to get the go-ahead to mine there ... and was agreed to ...

how much "unspoiled" native forrest do we need

[Woodman]

how much "unspoiled" native forrest do we need

More than we have now.

Another question to ask is how much crap do we need that uses coal to manufacture?

not everyone can sustain themselves by making jams and dream catchers and living in a housebus. they require or want real income for their family

*Disclaimer: I have no knowledge of mining procedures, risks or stratedgies*

But if it were my mates and son in that mine, I'd be baying for blood. As I'm sure the poor folk involved are now. It's four day, FOUR DAYS on, and nothing appears to have happened other than some drilling and a shitload of new conferences. I simply can not believe, that there's no breathing aides that a team could have been dispatched immediately. There is no shortage of volunteers. Campbell showed an interesting comparison between a similar scenario in the states, 4 hours before the rescue team went in. They had to retreat many times, but the effort was made.

In todays day and age, I can not believe that there is no way for a team with proper breathing and backup equipment to be armed with gas analysers and begin an expedition.

These are peoples SONS, FATHERS, GRANDFATHERS and BROTHERS for fucks sake. Let those who would take the risk, take it.

Too much erring on the side of caution? I believe so.

Sorry bro, I don't think we're on the same page here. There are steps that can be taken to ensure risk of a second explosion is minimized. What do you think is done when they have a leak or major rupture on a drilling rig and need to evacuate? Tell everyone to hide under theirbed and not move in case they cause an explosion?

There are instruments to detect gas levels and from what I can tell, there's no reason not to moblize people as far as they can safely travel. At the moment, they don't know whether the gas levels are high, low or non existant. Why aren't teams moving as far as they can safely?

And dont you just look like a keyboard warrior right about now jimmy

It seems that well paid occupations are either shit jobs ... or come with some (read a high) degree of risk of injury/death ... and many are quite willing to accept that risk.

I myself had similar occupations of this type ... I took the risk ...

I got lucky ... I survived ...

The money rolls in ... and all is sweet ...

A nice lifestyle with all the trimmings ...

Untill the shit hits the fan ...

and then ....

The ... it will never happen to me ... happens ...

Their employers are accused of "exploiting their workers" ... by not keeping them safe ... abuse of their rights ...

Few things in life are totally safe ... shit, people even die in bed ...

Why do people forget that nobody lives forever ...

The old saying ... "Where there's muck there's brass" is still applicable in this day and age ...

[scissorhands]

With the political ramifications of National, mining, greenies and DOC, wait for the media circus, lies and PR spin to emerge oh wait.....the whole country is talking about this, and special behavioural scientists will be assigned to deal with the 'truth'.

Watch for yap dogs talking sides protecting their masters

Is the coal now on fire?

I know WT may be slow on two wheels but I think even he could have been in and out within 6 days.

[Banditbandit]

Is the coal now on fire?

Who knows .. good chance

Fire broke out in the Ironbridge Mine on the Denniston Plateau sometime before 1950 (not sure of the date) and is still burning today ....

[scissorhands]

I suppose if there was a chance of foul play ie: greenie activist tampering with the mine before morning shift... we will never hear about it.

Imagine the division within NZ that would cause.

Remember when the greenstone thief's helicopter fell out of the sky into Lake Wanaka shortly afterwards? Odd I thought.

[avgas]

So the "massive build up of methane" wouldn't have caused the explosion?

Nah more the case that the mine was not capped.....then they fed oxygen down the hole - in case someone was still alive.

This is why methane tanks don't suddenly explode in sunlight.
