I must have missed this one along the journey and it just popped into my feed… Non stop action here Dave, bravo 👏 👏👏👍

[@demolitiondavedrillandblast]

Glad you enjoyed it Swishy.

[@mattywho8485]

Nice work Dave, you obviously know exactly what to expect when you leave your own excavator on the blast pile!

[@demolitiondavedrillandblast]

Yep, please like and subscribe, I'm just about to put up today's job.

Nice mini-excavator drill. Something like that in the Tennessee,USA area is ranging between $4.5 and $5 a cubic foot. 6-7 aud.

[@demolitiondavedrillandblast]

35.3 cubic feet to 1 cubic meter, $6 AU x 35.3 = $211/m3.... I'll come to Tennessee I think! This home site gave up 60 truck loads of granite.

[@bigredracer7848]

349👍's up guys thanks again for taking the time for us all to be with you for the great show

[@demolitiondavedrillandblast]

349! wow thanks!

[@gaijininja]

Some home owners have too much money to waste. If there's solid granite under the the build site, apply to have a height change, and build on the ground rather than in it. Mind yo , watching Dave blow it all up is more fun for us.

[@demolitiondavedrillandblast]

This land was very cheap because of the rock.

[@WatchDogxx]

In the shot at 3:43 you can actually see a bit of a fireball. Any particular reason why this happens, and isn't noticeable in most other shots?

[@demolitiondavedrillandblast]

Oh yeah, well spotted. that from the plastic jacket on the 70g/m det cord, I've seen this on a few occasions. What happens is this the plastic gets super heated and vaporised in the hole but the is not enough free oxygen for it to burn, when the supper heated gas vents and meets with the air it produces a huge flame. Greg tells me from his viewing position, across the road it was Huge.

[@frozenjoe6313]

@@demolitiondavedrillandblast It might be because dave might have accidentaly dropped a bit of NM in the hole, just to help it along a little bit.........

[@stevehansen5389]

Would really like to see some pictures of this job after the construction was finished. Looks like you blasted the garage cut out all the way down to street level Does it have an elevator/lift?

[@demolitiondavedrillandblast]

Steve Hansen - The garage does not have an elevator, just stairs up to the house above. You can email me from my web site if you really want pictures. - Dave

[@romandybala]

Great vid. Enjoyed watching. Is there any significance of the stick or shovel laid on top?

[@demolitiondavedrillandblast]

Hi Roman, the calibrated stick and the Shovel are used in the final part of the procedure and usually stay close by. The stick is used to check hole depth and dryness prior to loading and to check depth of cover if required, if the shot is initiated by an electric detonator, then we use the shovel to put a bit of dirt over it to tame the bang of the electric det.

[@romandybala]

Thanks Dave, I like the compilation of blasts. Whats the small bang tha sets off the main charge?

[@demolitiondavedrillandblast]

Most of these shots use down hole delay detonators - each det has a 400ms down hole delay (second bang), the blast is initiated with either an instantaneous electric det or a shock tube stomper that uses a shot shell primer (first bang)

[@albertreed966]

Roman Dybala Good work. When I worked as a driller on Interstate 91/93 in Vermont aside from crushing the rock as it was blasted we also did the side walls through a cut leaving nice walls to look at. Sometimes it didn't look good, lol. I worked in the granite quarries in, Barre, Vermont.

[@thvtsydneylyf3th077]

Hi Dave, are you using nonelectric and what do you use to initiate it all at the start ?

[@demolitiondavedrillandblast]

Please email me for a detailed explanation dave at demolitiondave dot com dot au

[@vicbittertoo]

nice wall control there champ :), if it was my place Id leave the barrels as final finish :)

[@demolitiondavedrillandblast]

Same here, most of my best work is behind retaining walls or under concrete, sadly.

[@MrTerrymiff]

Love your work, mate. None of that wanky 'fire in the hole' crap. Just a good old Aussie 'let 'er rip'.

[@demolitiondavedrillandblast]

Yep... load it up, cover it up and blow it up. Thank for watching.

[@demolitiondavedrillandblast]

Just checked out your Ch. are you a Ham Terry?

[@MrTerrymiff]

Ham as in amateur radio operator? No. I was a technician in RA SIGS for 20 years. Fifteen of them based in Melbourne.

[@demolitiondavedrillandblast]

Gotcha Terry, just saw the video of the 2.4 Ghz power meter on your channel , that sort of gizzmology only appeals to radio types.

[@User0000000000000004]

Those are some pretty flash houses!

[@demolitiondavedrillandblast]

Normal for this area.

[@deathvalleyalex9485]

Oh look , the little drilling machine farted ! LOL

[@demolitiondavedrillandblast]

You may laugh but that little drilling machine has paid for itself many times over.

[@kevinbyrne4538]

Less like blasting, more like surgery. Lots of small blasts to carefully break up the bedrock.

[@reatonable]

Good to see a tradesman at work, they could nearly use your blast edges as internal walls.

[@demolitiondavedrillandblast]

Yeah, I went to a fair bit of trouble to make this one neat and tidy as the one next door was done by the opposition and it was a crater.

A true artiste.

[@demolitiondavedrillandblast]

Thank you James

[@russellsmith3825]

He wanted a house, and he got a quarry instead....

[@demolitiondavedrillandblast]

60 Dump truck loads of Granite came out of this home site!

[@johnc4774]

Can someone explain to me why this is so satisfying to watch?

[@demolitiondavedrillandblast]

It's blokes stuff.

[@dogwedl1167]

[@demolitiondavedrillandblast]

Thanks.

[@jeanhawken4482]

Goodness me. These are big rocks and looking down the road there are plenty more.

[@demolitiondavedrillandblast]

Oh yeah, there has been a few good jobs in this street!

[@frozenjoe6313]

Sweet. I guess its good there are plenty of rocks to break...........

[@demolitiondavedrillandblast]

There is in this street.

[@frozenjoe6313]

@@demolitiondavedrillandblast Have you ever considered using a medium sized manlift, and mounting a drill on the man basket.?. The type with the extendable boom, and it worthy of note there is a set of hydraulic controls down on the machine, in addition to the controls in the basket. Those things have considerable reach. and If you stay close to the ground it cant tip over as soon as the basket weight rests on the ground. Everything pretty much stops........................ and the controls are hydraulic. you can tap into the hydraulic lines to raise and lower the drill, and reach inaccessible places. OF course, its probably against the law tho., Try thinking you are a star, and can do almost anything.........

[@demolitiondavedrillandblast]

Hey Joe, I can not answer your emails because the return address bounces every time. do you have another email address that I can try??

[@mikethespikemorgan]

Do you tend to blast more bedrock or boulders in your work

[@demolitiondavedrillandblast]

Oh, Both, depends what you term as bedrock.

[@colincrooky]

And I thought Uluru/Ayers Rock was the biggest monolith in Oz Dave. Thank you.

[@demolitiondavedrillandblast]

Yeah that was quite a job Colin.

[@ke6gwf]

It's just the biggest one left after Dave's career... Lol

[@patmcbride9853]

I figure the warning siren was more annoying to the locals than the blasts.

[@demolitiondavedrillandblast]

Usually is Pat

[@biggles1024]

I'm loving your work. Subbed.

[@demolitiondavedrillandblast]

Thank you, I might post some more jobs soon.

[@TXManka]

What type of explosive and delay are you using in these shots?

HI Brian, this job was done with Orica "Senatel Magnum" 32mm packaged emulsion - www.oricaminingservices.com/au/en/product/products_and_services/packaged_explosives/page_packaged_explosives/senatel_magnum/88 and Orica "Gold Dets" - Nonel style with 400ms in hole delay and 25ms surface delay clip. www.oricaminingservices.com/au/en/product/products_and_services/initiating_systems/page_initiating_systems/exel_goldet/26

[@dhejdkdkdebjejdjdjs3523]

I thought you'd pour anfo directly in to reduce costs.

[@ralfoster5753]

Seems perfect for me 😊👍

[@andik859]

Dave you are blasting so much, your siren are broke down. Need a new one.

[@bobw222]

Interesting... at around 3:45-3:48 in you can see flames in the air after the blast.

[@demolitiondavedrillandblast]

Good spotting, this is the plastic sheath on the det cord igniting when the super-heated gasses meet with the air, apparently it can not get to combust in the hole as the reaction of the PETN in the det cord is already oxygen poor. I have managed to capture similar post blast flames on several occasions. From the camera angle it is not very visible but from where my assistant Greg was standing across the road it was huge.

[@bobw222]

@@demolitiondavedrillandblast Thanks for the explanation! I look forward to more videos.

Buon lavoro colleghi

Grazie amico mio.

[@lewiemcneely9143]

Good shooting. All you have to do is shake it a little.

[@Ramdodge582]

jesus, they really wanted that house there!

[@demolitiondavedrillandblast]

Elevated block with good views and very cheap.

[@josephastier7421]

Interesting secondary burn of the escaping blast gasses.

[@demolitiondavedrillandblast]

Congratulations on noticing that one, I assume that you are referring to the presplit shot, my worker assures me that from his viewing angle, across the road from the site, it was enormous. I've seen this on several occasions, all where detonating cord was used, I think that the petn detonation is oxygen poor and as such the plastic cover on the cord can't combust until its super heated gases mix with outside air. I have another video of this happening, I'll try and locate it. I've also had unburnt gasses ignight and pop when a shot was being dug out!

[@dhejdkdkdebjejdjdjs3523]

Yikes. Lol.

[@rossramsdell7584]

another idea might be to build elsewhere

[@demolitiondavedrillandblast]

The land was cheap because of the rock showing on the surface.

[@Tugabud2]

Ground burps. People must really be desperate to build on such lousy terrain.

[@jimbo20022002]

Gee, this house would have consted a fortune!

[@demolitiondavedrillandblast]

But the land was not expensive and the views are fabulous.

[@lebommjohnson8101]

Well shucks ! This technique is so UNspectacular as to be almost no fun at all to watch !

[@demolitiondavedrillandblast]

Yes, very unspectacular when working in urban areas, but it has to be or or I'm in big trouble. Maybe these jobs would be more to your liking - kzbin.info/www/bejne/hHbSeYeXhZ2WmpY or kzbin.info/www/bejne/fHyQXmqlZ8eZfas or kzbin.info/www/bejne/fouadnuBoMScfJY
