Year, my Google social credit score is not good because I speak out against Globalist ideals, leftism and any sort of corruption. It's just a subtle way of punishing me for "wrong think".
Dave, I wasn't sure it was you, without the red coveralls, then you spoke, and I was sure it was. A perfect shot, as always. I loved that zipper effect.
Was wondering if you found the keys to your truck. And sure enough. Trench blasts are my favorite to watch as the charges go off in sequence and moves down or up the trench. Thanks for sharing, Dave!
I don't know what a normal level of precision is in blasting, but that was quite impressive. This video is perfect with a second cup of coffee before a day of digging in clay. It just doesn't seem so bad now. Thanks, Dave! :)
Glad you enjoyed it 42, I think for any blaster with a good understanding of his work is able to provide this "normal level of precision in blasting". Interestingly I follow a facebook group for blasters that seems to be made up mainly of Indians and Africans - there is plenty of shocker shot on there!
Hello Dave I was looking at the Crazy horse sculpture videos from South Dakota USA. I never thought about how things like this were done . I like the diamond saws.
Hi Dave, great videos, could you perhaps do one on how you achieve the delayed detonations between charges, plus it would be interested to get some background on how you are licensed and regulated, checked!! Cheers from the U.K
Lovely sequencing from your delays Dave - always a treat to watch. I remember some trench blasts by big pipeline outfits that probably covered a quarter mile at a time! Most satisfying. :)
Glad you enjoyed it Chris, I've never done any that long as most of my trenching has been in new housing subdivisions and they have no time to wait while we spend a week drilling, as soon as they can get a few lengths of pipe in we have to blow it.
Awesome job Dave. I'd love to come and learn how to trench off you at some stage. Looks like you're using a different breed of surface delays this time with yellow signal tube.
There may well be a big opportunity for that later in the year Jim, These are Orica, old color scheme, the tubes were always the same color as the clip, no longer the way.
Is it sensefull to use high detonation velocity explosives like RDX or HMX where you want less lift and more fracturing? Set aside the cost, is the performance actually better
Dave, have you ever used explosives in a confined access residential area to blowup old concrete footing in timber retaining walls? I’m looking for a better way of removing posts. Jackhammering a 450mm x 1.4m concrete plug is tedious!
I bet it is Paul, you could try a 1.4m hole either side of the post and fill it with an expanding chemical cracking agent, that should do the trick, several strands of detonating cord could be good also.
Depends on the quality of the cover material Brain, if you have good clean soil then no carpet is required, in this case the cover had some broken rock in it which can sometimes damage the interconnecting tubes and cause a partial misfire.
Dave, you're one of the few people who can claim to get paid to uhm let it rip! *giggles* And you can be proud of it =) Also, I love the timelapse. It is quite the ominous thumping. Anyway, this comment was a lot of words to say I had a very rough night with a call to the cops (who were most helpful), and then your video came into my day and brings me joy. Thank you. :)
@@demolitiondavedrillandblast Glad you found the keys. Misplacing stuff happens to the best, at least yours were in a logical place. At one point I put the car key away with the groceries, in the fridge... yeah that took me a while to find. I'm clearly not as bright as they make 'em. 🤷♂️
Yes, the small white bucket is ANFO (granular explosive), the big white bucket is crushed rock to back fill the hole and keep the blast energy confined.
G'day Dave ! This might be a stupid question as I don't know a thing about explosives, but I wonder why you leave so much of these colored wires in there ? Wouldn't you save on costs by cutting them to the right length you need ? Also why do these wires have different colors ? Thanks in advance for your answer and for taking the time to share all these great videos ! :-)
The tails come with the detonators and it'd be more work to trim them than to just leave them. Det cord though comes on rolls so you can cut it to length. I'll leave it to our gracious host to explain the colours.
what made you decide to get into this line of work? Was it just the allure of cool explosions? And how did you get into blasting? was it apprentice system when you something taught at a trade school, or maybe a mix of both? Have you ever been other parts of the blasting industry like mining?
Good Morning Australia and Dave. I watch australia news and see the huge flood. Oh shit. Hope everybody is safe. Greetings from 🇩🇪 and good job. 👍 Stay save.
@@demolitiondavedrillandblast alright, stay safety. We have here in Germany a flood, watch Ahrtal flood. 40.000 Cars swim away, round about 200 death people. Only 150 Km away from my home. Hope you can spend some money for the people their lost her homes.
You need to come to Missouri, I work at a quarry and we have a water problem on one of our ledges. The first shot they did was 6 inches short leaving a dam that has developed a lake evertime it rains it seems that each shot is getting deeper as we move away from the high wall. I've asked the boss if the drillers can drill us a hole at an angle from the deepest point of the water down to the main pit floor giving us a drain.
About halfway through the shot, the "thuds" of the covered charges are interrupted by another sharp "crack" that sounds like the beginning of the shot again. What was that? Just a variation in the cover material? It seemed to dig out just fine, so it worked, I'm just curious what it was.
No, no, this was the crack out of the witness tube at the far end of the shot, you can see it here - ua-cam.com/video/g22tcWXbahA/v-deo.html at about 6:10, the Yellow tube is tied to the steel picket next to the tree.
Back around 1900, teaching how to do this was a standards part of an ag collage curriculum. No licence needed. IIRC if you are only working with dirt and the moisture content is right, you don't even need the fusing: just stuff stick of dynamite in at the right intervals, set off the one at the end and sympathetic detonations will ripple them all off.
I wonder if that tree by the trench asked it's mates, did the earth move for you guys also? Dave, you make it an easy choice as to which video i watch first !
Incredible that you dont use an extra weight on the handheld rockdrill. You must have soft rock almost allover too endure that. If I forget or dont have my extraweight the whole day is destroyed.
Interesting that you mention this Biorn, this was Brent's first time using a drill, so I gave him the light drill (RH571), I would normally use the RH658 with the air leg bracket attached - this adds 3.5Kg and does make a difference. I have been recently been thinking about adding extra weight. What drill do you use and how much extra weight do you add???
@@demolitiondavedrillandblast If I am forced to use the handheld drill machine I have 3 options. RH658/RH571 or a hydraulic driven one. I have 15 kg extra weight mounted on the RH658 an a loose extraweight of 20 kg to put on. To the small hydraulic drill and the RH571 I use only the loose extraweight of 20 kg
Your first in TG, the didg' - one of the three great Aboriginal inventions, along side the Boomerang and the spear - a bent stick, a strait stick and a hollow stick.
Dave, missed your videos. Had received no notification from utube. Checked this morning and wow there’s three or four videos to watch. Thanks buddy.
Year, my Google social credit score is not good because I speak out against Globalist ideals, leftism and any sort of corruption. It's just a subtle way of punishing me for "wrong think".
"I think you know the drill by now." Very nice pun.
Oh excellent! A new video right before bed! what a nice treat!
Sleep tight.
Dave, I wasn't sure it was you, without the red coveralls, then you spoke, and I was sure it was. A perfect shot, as always. I loved that zipper effect.
FANTASTIC to have you back making videos that are a BLAST in the new year!!, THANKS
More to come Jim.
Big blasting Dave is back. Nothing beats a good bang. Keep up the good work. Covid must be hard.
Nice filming on the Saturday , I liked the ripple effect ,
So you found your missing keys? Thanks for taking the time again to make grown men chuckle like kids 😁
Was wondering if you found the keys to your truck. And sure enough. Trench blasts are my favorite to watch as the charges go off in sequence and moves down or up the trench. Thanks for sharing, Dave!
Sure did, right where I left them in the excavator at the last job!
Thanks Dave. I sure enjoy your videos.
Glad you like them! Thanks for watching.
Another good one Dave. Thank you! It is interesting how you can hear each individual detonation in slow-mo.
Glad you enjoyed it.
Excellent job Dave, Cheers mate.

Demolition Dave blasting and deep earth tree massage. Great video. Thanks!
Glad you enjoyed it Brian.
Hello Dave I was looking at the Crazy horse sculpture videos from South Dakota USA. I never thought about how things like this were done . I like the diamond saws.
Very cool, that is a multi generational project, I take my hat off to them.
Hi Dave, great videos, could you perhaps do one on how you achieve the delayed detonations between charges, plus it would be interested to get some background on how you are licensed and regulated, checked!! Cheers from the U.K
In short, the plastic clips (surface delays) on the end of the tubes have a time delay detonator in them, Red = 25ms, Yellow = 17ms, White = 42ms
Loved the wobbly tree 👍👍
DD in your happy place playing with the bangers!!! I always look foward to your videos!!!!!
I appreciate that Bill, more soon.
G'day Dave great video and great camera angels mate.
Thank you Murphy.
@@demolitiondavedrillandblast Thank you for doing the video mate
Another great video. I bet some neighbours get annoyed when ya start the drill up with the noise, then the siren goes off only to miss the bang 😂😂😂
Nobody likes the drilling noise.
@@demolitiondavedrillandblast It's the warm-up band :)
Beautiful work Dave.
Glad you enjoyed it 2204.
Hi Dave, Great job - as always! Very satisfying to see the trench move like a giant caterpillar! The longer - the better! Stay well! Stay safe! Jim
Glad you enjoyed it Jim.
@6:10 - Seeing that shock come out of the end of that tube was really cool! I reviewed that a few times.
That is the witness tube, tells me that the blast has propagated all of the way to the end and no tubes have been damaged.
Lovely sequencing from your delays Dave - always a treat to watch. I remember some trench blasts by big pipeline outfits that probably covered a quarter mile at a time! Most satisfying. :)

He, he..
Its great watching old vids from a couple weeks back. Missing the humidity..... NOT
You need to watch them all Jase.

Explosives are just awesome. You can do so much work with them. Love the slow motion
The ultimate power tool!
Those two shots made gravel. Well done.
Thanks 👍, sure did David.
Thanks Dave that first blast was like a zipper opening up the rock. Majestic almost!
Glad you enjoyed it, sure did the job.
nice one Dave avagoodweekend mate.
Will do Amanda.
Is it sensefull to use high detonation velocity explosives like RDX or HMX where you want less lift and more fracturing?
Set aside the cost, is the performance actually better
Yes, in hard rock the performance is better, but the cost is very high.
Dave, have you ever used explosives in a confined access residential area to blowup old concrete footing in timber retaining walls? I’m looking for a better way of removing posts. Jackhammering a 450mm x 1.4m concrete plug is tedious!
I bet it is Paul, you could try a 1.4m hole either side of the post and fill it with an expanding chemical cracking agent, that should do the trick, several strands of detonating cord could be good also.
The ripple effect was very interesting,watching from the side View
Nice. That first shot, with the delays.....sounded like an oversize zipper. Brrrrrrrrrrt.
Always love your videos!
Glad you like them Kevin, more videos under construction!
I have watched this three times. It looks like a giant mole ran through the trench. HA HA HA.
I noticed in the past that there was no carpeting/covering on the shots. Do you do the carpeting/covering in tight residential sites?
Depends on the quality of the cover material Brain, if you have good clean soil then no carpet is required, in this case the cover had some broken rock in it which can sometimes damage the interconnecting tubes and cause a partial misfire.
@@demolitiondavedrillandblast Let's hope the wife doesn't notice her curtains are gone.
The first one sounded similar to an A-10. Fun to watch for sure.👍👍
So what makes the rock harder then others? Is it the grain structure or the type of rock?
Hmmm... abrasiveness, high density??
Crazy how the fabric comes through the fill to the top!
Everybody loves a demolition job….especially when it involves explosives!!
love those sequential multishots
Moral of the story: Always call Demo Dave!!👍
Oh yeah... the job I'm on at the moment is a classic case of this.

Few... good when the cops help. More video under construction.
That's nice work!
Thanks!
So you found your truck keys, then?
Yeah... they were back at the last job in the ignition of the excavator.
@@demolitiondavedrillandblast Glad you found the keys. Misplacing stuff happens to the best, at least yours were in a logical place. At one point I put the car key away with the groceries, in the fridge... yeah that took me a while to find. I'm clearly not as bright as they make 'em. 🤷♂️
That's an awesome sound. Just like a machine gun or a stitching machine 😊. Love your work man.
Can you half the dirt next time to get a bit more lift or is there a code of how much you need to put on top?
You really would not like to see what happens when you only put half the dirt on top.
Neighbours wouldn’t be happy?
Correct.
The stuff in the white bucket you put in the holes, how does it help you in blasting process?
Yes, the small white bucket is ANFO (granular explosive), the big white bucket is crushed rock to back fill the hole and keep the blast energy confined.
Gave that tree a good shake! Haha another great video!
Thanks 👍
what's the carpet for again?
To protect the plastic signal tube that connects all of the detonators in sequence.
@10:45 - Witness tube spotted again. Cool as shit.

Hi Gary, drilling a low angle hole out to the face from low points is an excellent course of action, I have done this to drain a difficult area.

...STARTING THE DAY OFF WITH A BANG...LOL..GOOD ONE, STAY SAFE....
Dave, you need to get a Menzi Muck A20 or an M545x with a drill for overkill.
Your thinking what I'm thinking. A local contractor (Woods Earthmoving and Plant Hire) have one... what a machine!!
If you had a seismograph I think you would see each charge detonate in turn.
Yes, you can.
