[QUOTE="dwt, post: 87057, member: 428"] G'day BrisJoe, the non explosive agent im talking about is not the airbag its the agent that you mix with water (EXPANDO), (DEXPAN) the blast pattern of the adit/portal cut is for explosivies not non explosive agents, as for the airbag style you would need a void big enough to fit the airbag (one 30mm hole vs 25mm x however wide the bag is) you would need to have cut a slot in the rock to fit the airbag in. The non explosive cracking agent i would use for the first part of a shaft sink until i got to some decent enough rock that could handle explosives(out of the sandstone bedrocks), and hopefully by that stage i would be well and truely on ore that would more than cover the expenses of having to start using explosives, this i will cover in some later posts :) you can read all about non explosive cracking agents at this link ;) [url]http://www.expando.com.au/what-is-expando[/url] [/QUOTE]
