it seems that one of there mates found a way into them actually talked with them
but the way he had found was deemd to dangerous to persure
incidentaly i sent a email to beconsfeild minig last friday about how to get though that super hard rock
by using a thermic lance i have used these before you can cut though concrete like a hot knife though butter
didnt even get a reply

Marray is onto something..."""""It is ideal for demolition work, where noise and vibration are unacceptable,"""""

What is a Thermic Lance?

The Thermic Lance is a consumable steel tube, packed with low carbon steel wires. They are usually supplied in three metre lengths with varying diameters. The lance is attached to a 'lance holder ', which is connected to a suitable oxygen hose fitted to a high-pressure oxygen supply.

Thermic lancing is the process of cutting and removing stubborn materials by thermo-chemical reaction. When ignited the lance will burn at intense temperatures and is capable of cutting or boring through almost any material.

Thermic lance boring is a method of boring and severing concrete, steel, cast iron and hard to clean materials without noise or vibration in a fraction of the time taken by conventional methods. It is ideal for demolition work, where noise and vibration are unacceptable, or where speed is essential particularly on reinforced concrete. The equipment is extremely simple and easy to operate, and the capital cost in comparison to drills etc. is negligible. A list of applications is available by clicking on the 'applications' button at the top of this page.
The process was developed in France following the Second World War, as a means of assisting the break-up of gun emplacements, submarine pens, and other large concrete structures. Thermic lancing depends on the fact that red-hot steel will oxidize very rapidly in an atmosphere of pure oxygen. When the steel is at red heat, it has reached ignition (oxidation) temperature. A stream of pure oxygen directed at the red-hot area will immediately form a film of iron oxide. The melting point of iron oxide (approx. 800-900 degrees C.) is well below the melting point of steel
(1,400 - 1,500 degrees C.) The velocity of the high-pressure oxygen blows the oxide film away and another film of oxide is instantly formed and blown away. This reaction is exothermic (gives off self generated heat) and will continue as long as red heat and the oxygen stream are present. The intense heat generated at the end of the thermic lance, when applied to a material will quickly burn through it and will also consume the lance. The burning action can be stopped anytime by turning off the oxygen supply.

Maybe it's not a good idea to use it in very confined spaces then

well is underneath a bulldozer a confined space
coz i have used one there
in the hands of a skilled tradesman this will do wonders
you just need to do the prep work
to do it safley
it doesnot matter coz the boys got out

I thought it was the guy from prision break that got em out!

Dont take this the wrong way - but im not suprised they didnt get back to you about using the thermal lance. In fact you're probably lucky they didnt reply with an email telling you what you could do with your thermal lance. Im familiar with using a thermal lance too - and as a rescue professional i'm not very patient with the guy standing on the footpath watching us work giving me tips on how i should be doing my job. I know that you had the best of intentions and im not flaming you, but Mines Rescue are well trained and well equiped, and i know that if a thermal lance was required they would have used it. I can say for sure that they simply dont need emailed advice from interstate. Again - there is no ill-intent meant on my part, just letting you know what its like on the "recieving end".

2 weeks underground is a bloody long time. Im wondering if the whole thing was a conspiracy ...... where's the proof they were underground at all ?????? Where are the pics ???? Where's all the rock ????

thats cool Ian
in the email that was sent i went to length to say that i wasent trying to tell them how to do there job but mearly offering a suggestion from out side the square.
i too have been trained in rescue techniques above ground confined space and below
ground but this was quite a few years ago

Yea i work as a driller on a mine site so can appreciate how hard the rock can be at times. I'm also a member of the mines rescue team. The whole time that the rescue team were working they would have had to continually stop and have other people come in to check the ground and make sure that what they were doing wasnt going to put anybody else in any more danger than is possible. That would have slowed things down dramatically (as well as the hard rock) but they are not allowed to put themselves in danger. As who wants more people trapped or injured. In any rescue the safety of the rescue team is the main priority (although in an emergency it is easy to forget that when trying to get someone to safety).
By looking at the scenario of the two guys trapped in the cage by a huge rock i think the rescue went well by coming in from underneath. Even if someone had have got to the guys from the side i wouldnt have wanted to cut the cage as that would have majorly weakened it and may have ended with the rock crushing everybody
