  • nice back music...Awesome footage! Great video. 

  • screw the bloody moozic, just the shots!

  • I love metallica and all, but I have heard them a thousand times. I came to this video looking to hear blasting. Do you have it without music?

  • Every explosion video like this should have Metallica in it ;)

  • Stemming to confine gases to utilize energy more effectively, some 3 to 4 holes have stemming ejections, but we can rate the blast satisfactorily in terms of fragmentation and heave, if possible use 3/8 inch aggregate for medium diameter holes, and 3/4 inch aggregate for big diameter holes to effectively confine gases in order to maximize energy utilization.

  • people who know more than this than I do... what is stemming and rifling?

  • A Handfull of 1/8 crush in each hole??? lol.. seriously... my boss used to get us to put in atleast a 5 gal pale of 1/4 in. in each hole :) no rifling.

  • Like mmpow said, almost every hole lost energy through the top, more stemming

  • That was a couple of pretty big shots. I did notice quite a few holes rifling. Needs more stemming :)

    Thanks for sharing.

  • Se där... den vart riktigt lyckad ju
