Talk:Rock blasting

From Wikipedia, the free encyclopedia

I'd love to get a citation in here for the usage stats, and perhaps more recent ones as well (given that those in the article are from 1990). And is 500 Tg a correct figure for Australia? That's around a trillion dollars spent just on blasting in 1990 there! Exerda 16:26, 14 August 2007 (UTC)

I think so - see [1] (I've added a Harvard-style citation to the article since google books urls are unstable and frowned upon). Lupin|talk|popups 03:54, 16 August 2007 (UTC)

Thanks for adding the citation! Exerda 14
