Three thumbs up for Dave and a spare one for the digger! These guys don't know what they are missing out on by not having a thumb!
Thanks Gary, not many thumbs in Aus.
Camera survives blast...falls off tripod next day....still works.....awesome
err... not working well, has some serious problems now, time for a new one I think.
This is bizarrely therapeutic. Love watching this!! You’ve got a very cool job…
Glad you enjoy it!
Dave, I'm so glad I saw your activity. You are so passionate about work.
I am! Thanks for watching.
The first rock island was like bursting a pimple. Very satisfying, oddly!
Oh, I have heard that there are videos on that topic Paul.
It’s cool how much dirt blasts can move. But by far open air detonations are satisfying.
I can't argue with that.
Great video! As a blasting worker here in Brazil i see some practices very similar to your. Thanks for share your job.
Thanks for watching Jian, I would love to see some video of your work.
Dave, I think you are going to be spending a lot of time in this area when they start building. Thanks for sharing your work day.
I hope so!
Plenty of random granite around there.
62 holes is one of the bigger shot lately ain't it? nice kick out on the first shot! definitely an advantage having a non built up site to blast in!!
Last big one a few weeks ago was 137 holes, this is good size shot.
@@demolitiondavedrillandblast well i'd say that 85% or so of your shots on camera are less than 50 holes or less so it's one of the bigger ones!
Just wonderful Dave, and a multipart series too. That last boulder was huge! Good work my dude.
Glad you enjoyed it, more to come next week.
29 👍's up demolition Dave thanks for sharing this great video
Glad you enjoyed it Scott.
More brilliant entertainment Dave. There were some fab blasts in that lot. Bravo 👏 👏👏
Thank you, more coming soon Swishy.
That Blowed Up Real Good! Nice shatter on that last shot. And the tease on the last few seconds - looking forward to that shot.
More video next week TC....
That was very interesting see much more detail of the work you do to be able to make a bang. Loved it.
Thanks David, in the next video (mid next week) I will talk about one method of tackling a difficult trench shot.
Hah - the "rock island"! - nice drilling that with the machine. That took some covering too - nice bang :) That next rock was a pretty large 'slab' - looked like a good 30 holes... (33 I think I heard you say). Very nice uniform lift - and result. Next - heck, another real monster... phew, 62 holes. Looks nice soil there. Another nice lift and result.
Had to chuckle when you said on that previous video that you had your hard hat blow off twice - sure looked wicked windy.
Oh, not just twice Chris, it blew off lots of times but twice it ended up in the big puddle. Thanks for watching.
Well done Dave. That castle had a moat.
Sure did, glad we had a good size digger to fill it in.
The camera on the first shot was a bit to close - got a dirt shower! The 62 hole shot was awesome! Very little - if any - landscape rock after that one. This entire job is exciting to watch! Truly looking forward to part 3! Great job, Dave! Stay safe. Jim
Thanks for watching Jim.
cheers Mr D -that rock at the end was a fat whopper -made into pebbles by your hand😂-stay safe and well xx
The power in this shots. Wow.
Strong medicine for sure Jean.
What a shattering video i couldn't help myself I had to say it lol.
Excellent work as always Dave.
Glad you enjoyed it Scruffy, more next week.
Every job done safely and precisely
Thanks, I try hard Big Ears - in this game you are only as good as your last blast.
Another top video , Broke up it was spot on , just the right size for a small bucket . The shot at the start of the break out was brilliant . Keep doing that and you will be in Hollywood !
Thanks Bob.
It's always a blast to watch your vids Dave,
Thanks Poppy, always good to have you watching.
0:10 Here, the legendary golf course designer adds the finish hole on the world's most difficult golfing hole.
Funny you should mention that, I'm continually picking up golf balls on the site.
As an electrician I think this is wizardry. You take giant rocks and make them baby rocks.
Thanks Leland, it's not rocket science though (I have and electronic background in a specialist field).
Just keep doing it Dave!!!! We love it!!!
Ok... I'll do that Boss.
it never gets old hearing them dets go off in sequence
Oh yeah...
Now those are some big rocks good vid.
Thanks Emilio.
Great job👍🙏
Thank you 👍
Great as always, Although for a 300 series that seems like a very narrow digging bucket they have on it, compared to the other larger grading buckets which obviously move more.
That is what the customer wanted.
Another great video Dave .
Glad you enjoyed it William, part 3 next week.
Your videos are great fun to watch, have a great day and I hope to see many more
Thanks Ken, there is about 200 videos on my channel to check out, another one coming later this week.
To be continued!! Woot Woot!
Nice One Dave !💣💣💣
Thanks 🔥
All right, a bit of credit to the fellow who named this development! Hit the nail on the head he did. Ought to be a Demolition Dave Avenue, somewhere in here!
There is a Dave's corner on South Face Rd. - th-cam.com/video/HZ7EHKk_iF4/w-d-xo.html
Watching the first blast made it clear for me why you usually dump a lot of dirt on the rock. This must be a great project for you using that drilling machine. Looks a bit more comfortable drilling the holes. I noticed that using that machine you still wear some kind of mask? Looking forward to the next video.
Yes, even although the dust collector works quite well, the unseen lung clogger is the large amount of oil that I add to the drills air supply, this one needs a lot of oil or they chew out very quickly and cost $$$++ to rebuild - so a lot of oil is good but breathing it is not so good, believe me.
They certainly picked a rocky place for a street. That should keep you busy for a while.
Yes, I hope so... and then when people begin to build.
@@demolitiondavedrillandblast You might want to build a house there!
That is what the Trouble and Strife said!
Nice Machine Control system on the Kobelco excavator (Leica)
Yes, it is and it is very good!
Excellent video as usual mate
Thanks again!
Love the slo mo.
Thanks for watching AR
"Breaking the world one rock at a time" Demolition Dave......that's a t shirt I'd buy 👍👍👍 lolol.....heres a question...how many types of explosives do you use ? Are there different brands? I heard you mentioned after the blast how you liked a certain aspect of the blast. Great vid👍
Almost all of my explosives are Orica made packaged emulsion because it works well and that's what my supplier sells and ANFO, The chatter that you picked up on was about a trial that we might be involved with somewhere down the track.
Dave the fact that your camera survived the second shot is amazing. I had the sensation that I was going to be injured. Great shots. I love the drill on the mini ex i hope it saves your body.
Hi Greg, that slow-mo was taken with the DGI Osmo action cam - very similar to the go-pro - it is a very small target and fairly tough little camera.
Nice camera work . You showed how much running around you do on a job . This looks like a very big job .
I sleep good at night Chris.
Dave is there any chance you could one day show us watchers, what can happen if you over load a shot. Only if it is safe for you to do so, and another bloody good video again 👏 👍 👍👍👍👍
you mean like this? - th-cam.com/video/VlDazC1RWpk/w-d-xo.html
...ahh, more big bangs....lol...good one, stay safe and have a great week...
Thanks, you too!
You have the coolest job on Earth. Just watch your fingers.
Thanks Bucka, make sure you like and subscribe!
That was so good it felt like i blinked and it was finished u can sure move granite
Part 3 next week Craig...
Great video .It was a Blast
Glad you enjoyed it Robb, please like and subscribe, part 3 coming next week.
@@demolitiondavedrillandblast i am subscribed and like every video
Dave, great shots again. Thx, question "what happens with the blasted rock, roadfill?"
Good question, not sure what happened to all of the rock from this job, some times it goes to a crusher, other times to the lanscape industry etc.
Oh, Davey......, what do you do with all the rocks? Cheeky ay? A 3 parter!!
I don't know what will become of them AR.
4:20 is that the Chinese sharpener you got a year or so ago?
Yes, saved me a lot of money.
I noticed that to😀
great mate greetings from borneo
Hello there! Thanks for dropping in from Borneo.
Blowin’ stuff up is the bees knees , by the way if ya hang a bag with sand in it under your tripod it won’t fall over in the wind , can’t guarantee a hit from an excavator tho.
Yeah, I should try that.
Thank you dave for this video enjoyed every minute love from india
Thank you for watching! More coming soon, lots of jobs waiting.
Should have kept that first rock. Would have been an interesting water feature.
Not up to me FF.
What kind of licensing is required in Australia for explosives? Also how much insurance ream you out for when they hear you use explosives near residential neighborhoods?
In Australia a license to use blasting explosives is required and this is a multi tiered system with many endorsements available, Insurance.... you don't want to know, it's fairly obscene.
Looks cold there! Does it ever snow in your area? Big rocks big machines BIG explosions!!! Another great video!
It snows in the mountains near by Thomas.
What are the cutters on your sharpener made of ? Those drill buttons are incredibly hard.
The sharpener has little grinding cups that are shaped like the profile of the new buttons and they are diamond encrusted.
Nice stone to made cal viva a material use for construction
Yes, thanks for watching, some stone has already been sold to make retaining walls.
Granite is some hard rock to shoot, usually need high velocity basting agent but not a large Lb per delay.
Correct.
@@demolitiondavedrillandblast on a good note it's pretty predictable, unlike the Vertical seam grey shale we have in our area here.
No rock with seams is good SM
I’ve never seen rocks like these, where I live a rock is a flint the size of a fist, this bit of England used to be seabed - all gravel. Are the rocks you’re breaking up part of the underlying bedrock or have they been dropped there by some transport mechanism such as glaciation or perhaps a watercourse?
All weathered away from underlying bedrock John.
You need to work out a deal with a quarry for all that rock
I wish That I had a small crusher and could crush it onsite.
Dave, what is the difference in VoD between your emulsion and your det cord? When you use the det cord on a shot, do you just stick a single strand in a hole? Do you cap it and does det cord get delayed like your emulsion shots? I'd really be keen to get some more technical information about loading shots. If you have done that already, i apologize for not finding it already.
Hi TG, the emulsion Orica Senatel Magnum and the VOD is ~3400m/sec. The VOD of cord is ~7500m/sec. Every hole still gets some emulsion, which does the work, the cord just joins them all up. Usually no delays used.
You got the grinder working again!
I thought it had croaked.
No, all good now 42.
I was not expecting part 2 so quickly. Awesome video as always Sir 🥰 one question ? My wife and I were arguing over what the grey smoke that comes up from the cover pile is after every explosion. I reckon it’s residue from the explosives, she thinks its granite dust from the stemming?? Thank you sir 🥰
Bit of both TinMan
@@demolitiondavedrillandblast perfect! Cheers.
An excavator bucket with a sieve bottom, the width of a rock bucket, would sure be handy. I mean, if you had one for each size of excavator you have to work with.
From the looks of things this job is going to keep you busy for a while.
They need a portable jaw crusher there to run the rock through so they can use it for the road bed.
Would be a handy way to keep the material on site and not have to dump it. But crushers are not cheap and for how Little Rock their is idk if it would make it worth the cost.
Yeah, I wish I had one, have been thinking about how good it would be to have a small skid mounted unit that could just move around on my tilt tray truck.
@@demolitiondavedrillandblast I've seen photos of a smaller trailer mounted crusher with an out feed belt and then one that is used on a excvator.
A skid mounted one with an out feed belt could prove to be handy. Better yet mount one on an old mini-excavator chassis for greater jobsite portability.
I work in a quarry when we got the self-propelled jaw crusher it was working on a jobsite about two weeks before it came to the pit. All they were doing was running blast spalling through it to clean up the build site before it was hauled.
The guy running it said they were getting an easy one and a half truck loads of rock in a dump truck after running it through the crusher. It would depend on how much rock needed to be moved to make it practical on a site.
@ Kriss Femmpaws - It would not be economical to get a regular portable self-propelled jaw crusher in for a job this size, but good for a small unit.
That's a cool little drill bit sharpener. I never knew such a tool existed. How long can you use a drill between sharpenings?
A lot, in this type of Granite, probably about 80m and it would be fairly tired.
Howdy from Sacramento, Dave! Those are some substantial sized rocks. How would you classify the shots in this video? Do you have a sizing guideline? Cheers!
I would call these medium size shots.
Love seeing the rock getting pulverized. The rock drills you use, are they from Sandvik?
The drill on this little digger is and Atlas Copco Panther or BBD94, the hand drills are an Indian made copy of the Atlas Copco RH658.
Just curious on the mechanics. You drill a 1.6m hole, you fill the bottom of the hole with 10-30cm of magic stuff and cap it off. When the fairy powder goes boom, the whole rock breaks pretty symmetrical it looks like. Why does top of rock break just as much as bottom of hole rock. Love the videos and the details.
Good question CC, It does not always go just right, in order to get it to work just right you have to juggle a whole lot of variables that are all interrelated, for example the load rate in grams of explosive/m3 of rock, the hole diameter and spacing, the hole diameter to depth ratio as this greatly effects the distribution of the explosive, The choice of explosive etc. The rock is usually more smashed up toward the bottom of the hole, thanks for watching CC
The never ending story. 👍
Yeah, lot of rock on this hill!
This is going to be one of those addresses that you just keep going back to.
I hope so.
"Get your rocks off"... Phone Demolition Dave, it'll be a blast..
Wish you could do a couple of these uncovered haha
There plenty of uncovered blast videos on my channel Matthew.
@@demolitiondavedrillandblast Oh I found those don't you worry!!
👌👌👍👍
11:45 like a Mexican Wave but better......
Why don't you use blasting mats? Quicker to cover and easier to dig out when there's no soil mixed in the rock..
Do you run multiple paths on the det cord, in case of failure at one point? Why do you leave some sticking out the side, is that a safety thing, so you know it has all "gone off"?
It's not det cord, these are hollow plastic shock tubes
@@demolitiondavedrillandblast Cheers!
Hi Dave
Have you ever found any opals or gold in your demolitions?
Not yet DP... still looking though.
The second shot was 33 holes. How much would a shot like that cost in terms of explosives?
Explosive cost about ~$1100 AU
The big question, is the company that hired you for the road also putting in the housing? If yes then this is a long job, lots of content. ;)
No, they are gut doing the earthworks, road and underground services. The home site carve out and pools and stuff will be over the next couple of years, I'm sure that I will be back here a few times.
Hi Dave, what new burb is this going to be? North or N/East?
Can't tell you until the job is done.
Have you ever covered a shot then realised you've covered up the end you need to fire it?
Not when I'm covering it, but yes I have had guys cover the lead in after having it explained to them! It pays to be watching very closely.
How do you. Work out how much dirt you need on top
Depends on lots of variables Mike, primarily the load rate e.g. grams of explosive per m3 of rock and the depth of stemming.
Beleza 👍👍👍😎

Dave, I have noticed over time, you have different people assisting you setting the charges. Do you teach, or instruct people starting out in the Rock Demolition Field? I know not all are young guys, some look like good friends, who are experienced in demolition, just helping you out. It is just an observation that has posed the question. You have too much knowledge, not to pass it on to the next generation of would be rock reductionist, using extreme sudden force. Thanks for another great video. Be safe. Cheers.
I have 3 guys part time that have a lot of experience working with me, 2 with 11 or 12 years and one with 20 years experience helping out.
@@demolitiondavedrillandblast I am glad you have some help. Thanks for the fast reply. Cheers.
Love the slow motions, when you hear those pops first, and boom little later. Are those pops some nonel things or stuff like that?
Great video dave
Yes they are the nonel tubes from the end of each row that stick out from under the cover as a witness tube so that I know all of the holes have fired and no tubes got damaged during the covering operation.
It’s too bad you had to cover those big shots, would’ve been spectacular. With a big job like that will the contractor share your information with the people who buy properties there for you to come back and help with basements?
Oh for sure, I'm already in talks with one property owner that wants a pool there, They would be crazy to build a basement here.
@@demolitiondavedrillandblast Cool thanks for the info. Right of course, I’m from the Canadian praires so everyone has a basement would be rare to not have one.
I don't understand why you take the broken rock and place it on the ground nearby instead of loading it on a truck and hauling it off for disposal. Are you getting paid by the hour?
Are granite boulders that common on every jobsite?
On this job truck access has been a big problem because soft ground and so much rain recently, seems we are lucky to have Two dry days in a row. The rock is being stock pilled in one corner of the site - when we are able.
I would like to see that rock crushed and reused
Oh, I assure you it will not go to waste, already people inquiring about it.
Looks a bit like Lysterfield
Shhhh...
Eh Mate. Whats the blue thing that he keeps putting over his face
Hi Travis, This is a high quality half face respirator with an organic vapors canister. Even although the dust collector works quite well, the unseen lung clogger is the large amount of oil that I add to the drills air supply, this drill needs a lot of oil or they chew out very quickly and cost $$$++ to rebuild - so a lot of oil is good but breathing it is not so good, believe me, and although many people might think this is a non issue... If you are breathing this oily air every day it does not go down well.
Blasting rocks isn't that geo-cide
I think you are onto something there! I'll use that.
I dont want to be unnecessarily whining about safety And I know you are a shining light in a sea of mediocrity when blasting,saftey, , a regular rock star of explosive power, so tell me. are you using electrical detonators, signal tubing or what to initiate..? You were talking about rain, we can see clouds,..thats usually not good news, and did you use meters to measure ambient electricity before pushing the go button///How did you do that bad boy ?Thanks.
I'm using nonel dets and electric firing, email me for exact method explanation. No need to measure ambient electricity, just observe the normal precautions e.g. no use if thunder storm is looming, safe distance from HV powerlines and radio transmitters etc.
