December 2010[edit]

Thank you for your contributions to Wikipedia. In the future, it is recommended that you use the preview button before you save; this helps you find any errors you have made, reduces edit conflicts, and prevents clogging up recent changes and the page history. Thank you. Chimpanzee+ Us | Ta | Co 16:16, 20 December 2010 (UTC)

AmBX[edit]

Hi. Yep, that's exactly the right place to leave messages! :) "AmBX" (as it is now) is correct by Wikipedia's policy on trademarks so it shouldn't be changed. I notice that it is written "amBX" in the article body so these should be changed to match the title. You might want to note the strange capitalisation in the introduction though. Something like:

AmBX (officially stylized amBX) is an internationally patented technology..."

is a common way of doing this. Finally, I also noticed that you've added external links within the main body of the article. You shouldn't really do this. External links should nearly always be reserved for the "External links" section at the end of an article. Only [[wikilinks]] should be included within the main body. WP:EL gives more information about how external links should be used.

Keep up the good work though. It takes a little while to get your head around the correct way of doing things on Wikipedia but there are a couple of policies to get you started :). Drop me a message if you have any other questions. (...and remember to sign you talk page comments with ~~~~) Chimpanzee+ Us | Ta | Co 18:36, 12 January 2011 (UTC)

AmBX UK LTD[edit]

Hi Stevenxlead. Sorry for tagging your articles like that. It was part of the new page patrol work I usually like to carry out. More info here, WP:NPP. Looks like you really brush up the article. Your references look fine. You are free to remove the tags once you fixed up the article. have a good day. --Takamaxa (Talk) 11:16, 20 January 2011 (UTC)

gas pressure blasting[edit]

Gas pressure blasting or propellant blasting is the use of a low explosive[1] deflagrating (see deflagration)[2] pyrotechnic charge to break hard rock. The process can be used in mining, dimensional stone quarrying (breaking down or splitting large rocks above ground), above ground and marine demolition (breaking concrete/hard structures).

[edit] Background

A deflagrating/non-detonating explosive process is a "low energy event" (low explosive) as opposed to a high explosive detonation, the pyrotechnic charge burns and generates large volumes of gas, which when contained in a drill hole, creates pressure which heaves the hard substance apart rather than shock wave blasting it apart as with high explosives. The process is similar in practical use to high explosive blasting, where a hole is drilled and a charge/pyrotechnic device is placed in the hole then detonated/ignited.

Gas pressure blasting can also be carried out with a specialised high pressure re-useable carbon dioxide sytem, known commercially as Cardox [3] which uses pressurised metal cylinders to blast. The Cardox system has non-explosive uses in silo unblocking and is not widely used in commercial hard rock mining/blasting.

[edit] Differences

Two key differentiators between deflagration and detonating (in relation to blasting) are;

The speed of the reaction/process. The pyrotechnic process operates around the 100 metres per second range whereas high explosives are typically in the 7000/8000 metres per second range.

Storage and logistics. Without containment the pyrotechnic charge will not produce a large reaction of any kind and will just gently burn out. The high explosive charge will still detonate with potentially damaging consequences, material handling logistics are therefore vastly improved with the pyrotechnic process and charges.

The gas pressure pyrotechnic blasting process has been around for some time (since the 1960's), although there is very little available historic information available. It's use up until 2010 has been at very low levels compared to the more traditional high explosive blasting, as it was unreliable (high failure rate of about 30% underground) and it required an additional process that was labour intensive, making it less cost effective.

The major drawback of the early gas pressure blasting method was the additional process of "stemming". Stemming is the filling of the drill hole (post charge insertion) with an inert and sufficiently heavy material to retain the charge in the drill hole until it achieves it's maximum non explosive heaving effect. Stemming is a manual process and operatives needed to be skilled in material compositions used (normally locally sourced sand mixtures)and in the consistent packing of the drill hole to produce a good stemming effect, hence the high failure rate.

[edit] Benefits over high explosives

Suitably stemmed and without the traditional stemming failure rate, the system has significant benefits over traditional high explosive blasting;

greatly reduced fly rock
negligible vibration and noise
reduction in noxious nitrate fumes (no nitrates in pyrotechnic charge)
coarse fragmentation in mined/demolished medium results in significantly reduced dust levels
reduced logistical issues - transportation/storage
unattractive medium for terrorists - harmless unless embedded in hard rock
improved health and safety - no unexpected explosions even if set alight
reduced down time - operatives can work in much closer proximity to blast face
higher productivity due to potential continuous mining
reduced destruction of precious semi precious stones/gems - bigger gem stones due to low impact heave as opposed to destructive shock waves produced by explosion
environmental benefits - use in environmentally sensitive areas where explosion is not allowed/desirable (built up areas/marine/nature reserves)

A number of commercial gas pressure blasting systems/devices (non-stemmed)are currently available, such as Nonex from NXCO and PCF (Penetrating Cone Fracture commercial non-stemmed gas pressure blasting device) from Brandrill [4].

[edit] Self stemming products

In 2010 a UK patent was granted (international patent pending) to DGP (Global) LLP for a self stemming directional gas pressure device (GasBlaster).[5] This piece of intellectual property (which had been prototyped) solved the problem of high failure rate and removed the necessity of stemming and the stemming process. The device can also be used at any angle which had been impossible with a secondary stemming process.
