Carefully controlled trench Blasting through Granite (4K) 

They are Cheering at Ye Olde Mucky Duck, when Demolition Davey cracks the lot. Detritus is his Midas Touch, when the wiz-bang bangs the granite rock and rock 'em sock 'em now they're dust. So it's always the devil-to-pay when Demoliton Dave blasts away!

You have a really great eye for how you film what you're doing. Not everybody can do this.

I don’t get tired of watching this channel, it’s oddly soothing - mostly. It is also a good reminder to me (who has been lucky enough to never live near a war) how brutal it must be to be near shells landing… But mostly it is fascinating, and satisfying! Thanks for making such good videos while you work!

I am constantly amazed at the amount of big rock that you deal with. It’s not like it’s one or two big chunks, but everywhere on a lot of those sites.

I kept thinking, why doesn't Dave wear a tool pouch instead of putting the tape and knife and stuff in his pockets all the time, so inefficient. It's like you heard me thinking about it and talked about fishing stuff out of the blast holes. Too funny. Thanks Dave always entertaining.

Everyone is a genius at least once a year. A real genius has his original ideas closer together.

I mean ... *the chances of those polaroids being found again* out in the middle of nowhere? Some old dudes be like "hey, you said you buried it real good!" 🤣🤣🤣

These trench blasting ones are really satisfying.

Great job Dave, you and Ben made quick work of a tremendous amount of rock! Impressed as always. Glad to hear your feeling better!

1.1K+ 👍's up demolition Dave the most explosive man on RU-vid Thank you for sharing 🤯

The new mic plus the during-loading commentary is the kind of video I really, really appreciate. I'm a detail guy which is why I ask endless stupid questions.

Was expecting you to uncover a body from the 70's with those pictures under that rock, O well maybe next time.😬 Fantastic video and really like the way you talk us through what your doing.

Thank you Dave. So many perfect shots. Even the roos like a good blast.❤😂😂😂.

Nice mixed bag of shots there. Enjoyed that! Cheers.

Another great video Dave .

another enjoyable video. those polaroids at 17:00, because you have a lot of australian viewers, someone might recognise them. that would be nice. i'm surprised they survived that well after a period in the ground.

That's a fair old dose on ANFO you had to use. Must've needed a tuck load to do all those holes. Another occasion where a thumb on the excavator would have made the clearing up easier. Those polaroids are an unusual find, as is them not being long turned to mush.

That job was extensive. Glad your feeling better. Those pictures were a blast from the past!

Always a fun time. Thanks for taking us along!

Thank you Mr D for your time and effort in filming/editing and sharing this with us- its much appreciated - please stay safe and well x

Pouring cough mixture down the hole. Good video like always

The new camera and microphone are amazing Dave. I still go back and watch previous videos, but get spoiled pretty quick. Thank you for so much good content, especially the uncovered shots.

Another great video Dave. Hope you are feeling better.

interesting in the long shots to hear the the skips for the unloaded and loaded holes

I like the neatly segmented nature of the work; no guess-work, just boom job done.

hope yer feelin better , ive had a half dozen aquaintences from the i-net down with the coronary virus this month stay safe Mike

So much easier when you have the big machine drilling your holes!

That 32 shot slow-mo reminded me of the worms from the movie Tremors. Kevin Bacon starred in it.😅

Great audio and video quality Dave!

Dave, Thanks for the great video !!! I like the Drone shots and the super slow motion... Really good stuff! Your a hard working man so taking time to make these videos is very much appreciated. Keep up the good work and Thank You !!!

Nice. Plenty of shattered and bulked up rock. That blowed up real good.

MM77 Approved 👍🏼👍🏼……………………………………………………………..I know you have a hard job, but it’s one of the COOLEST too! LOL……………….Those pictures, how and why? Maybe do a google image search or something and maybe find out who they are……………….or were!! I honestly expected y’all to eventually find remains. I’m glad the vid didn’t get you down too bad and I’m glad you are better.

Wife asks how was work... Great, I had a blast❤

I really enjoy these blasting videos, but you know that! I never miss a show. Today's question comes from me; AT 1:25 YOU ARE SHOWING US THE INSTALLING OF THE BLASTING CAPS. HERE'S THE QUERY: COULD YOU SHOW A CLOSE UP OF THE INSTALL?

Apart from time needed for drilling, watching you set charges reminds me that that is in itself pretty time consuming - predictably with a trenching job! Nice view down the hole. Presume the pour on top of emulsion was ANFO. How nice if you were able to just add stemming and not have to bother with cover, just to keep the neighbors happy. Great slo-mos again. One heck of a lot of trenching and a PITA when damp in holes! Fascinating find with the polaroids! Another great video Dave, thanks. :)

11:28 the clevis on that digger is driving me INSANE

Great video , shame the camera missed the one shot , you certainly made up for it with the length of video and the skippy's making a cameo.

22.43....that one hole with a little less cover...... fantastic!

i was taught to use a half hitch when securing the det in the emulsion powder mind you that was forty years ago and tape was like gold lol

I thought that white pudding I had on my breakfast in Sydney tasted a bit odd. The farts after were violent.

Thanks Mate for the Bang up Videos. Crack on !!!

Nice one, as always. Thanks Dave.

good job mate

a great video Dave.a lot of work even with the drill rig.ive found fresh air and plenty of hard work will cure most things!!.

Great video of some spicy sausage with a little white sauce for the win! Stay healthy Dave!

As always Dave you don't disappoint and the cover gets very air reiterated. But I wish you could do some shots with out cover. Stay safe mate and the family 👍👍👍

Howdy demo Dave

Smashing good times.

Brilliant as always Dave 👍👍👍

Wish I could get a license to do this here on the big island of Hawaii. It’s all solid rock here and they make us use excavators with hammers that take ages to get the job done and kill the machines.

Sorry to hear you were down with the v. Dad used to mix up some liquor and hot tea...worked for most everything! Question on the packaged explosive...if the emulsion gets wet will it still fire or is it totally useless? How would you handle that?

Morning Dave 😊 Greetings from the Netherlands 😎

Weird finding those photos, I wonder what the story is? On the 18 hole shot, did you get a hole in one? :) Glad you recover from C. Thank you and have a great day.

Very interesting with those Polaroid photos. They have me wondering how they got there. Were they under the rock or on top? Maybe they were put there to just to puzzle anyone who found them.

Big drill Ben ?? Sounds like you are getting your monies worth, and that is really good. The next part of the drilling machine to break might be your back,..and we absolutely cannot have that. Maybe you could mount that man killer drill on lift, the type with a man work basket hydraulicly operated. That type of machine is called a " Zoom Boom,in Idaho and it has hydraulic controls down on the side of the machine chassis. in addition to controls up in the basket, and used but not to worn machines can be found pretty cheap.. You wouldnt even have to be in the basket to operate the zoom boom and the drill., maybe you can get away with using the longer drill steel to start with instead of using short steels to start, and then switch over, from short to long ., install some hydraulics and solenoids and some of those zoom booms have 75 feet of extendable boom. You could possibly mount that drill on the man basket, and reach places to drill you couldn't before, without straining yourself.... I might take a little of that horse paste myself, if needed and find just a little about the size of a pinto bean for 3days works great. . But I would never take anything denied by the medical docs . It might kill my pet tapeworm or something.............

Impressive video. Thanks Dave"!!!

Thanks to Sony we don't know how fast that magpie can pissoff ...pretty fast no doubt 😆

Looklng good, those new Volvos are great, what happened to the blade on it ? Any holes are a magnet for phones and keys etc, was only last year and I dont't often take my phone off its leash but I had to do some calculations, I was standing near a pier hole about 5 metres deep, it had water and mud at the bottom,,, well guess what my 1800 dollar phone decided it was time to slip out of my hand and aim itself right down the hole, I tried to fish it out with wire and other various methods but all failed, so I dropped the auger in and gave it a gentle quarter turn at the bottom, well I was half lucky, the phone came out undamaged and was still working but it soon shut down as it had been under water for too long.

I've never noticed the ground heave outside of the covered holes like it does @8:34

Could you maybe give us a little talk on why patterns and delays and why they are used? Something like a little chalk board thing with maybe some stills from your blasting to explain for us new to the channel types who know nothing but are curious?

It's good to see those shoots on camera. I wish we could have done that when I was in Greenvale you see what went right or wrong. Great show ❤😂🎉😢😮😅😊

Hi Dave, Sorry to hear you got the chinese crud! Glad you had some secret potion to make it better!! Hope your family is safe! Love the 30 minute video - lots of boom-booms! Got a good chuckle when I saw you pouring that big plastic cup full of anfo into each hole. Thumbs up! Stay safe! Stay healthy! Jim

well the pics at 16:45 seemed to have been "a blast from the past" 🤔😁

Really enjoyed this video Dave, the change in the condition of the ground is amazing. I’d have thought that you’d either have rock or not, but some of each seems like a pain in the arse for you, and then throw in the water! Glad you didn’t have too much problem with the Covid, just don’t go injecting bleach into yourself. 👍🏼

HI Dave ! 🙂 A few questions. 1. Why did you use a down-the-hole det and surface connector instead of just a single EZ-dets? Is it cuz it's what you had on hand? 2. What timing did you use for the down the hole det and surface connectors? 3. What diameter holes did your friend drill? 4. That is a big ANFO pitcher. What size pitcher is that when full? Thanks!!!!

I'll bet that little camera overheats. But man, does it do a good job for under $20k. The toning and AF while inspecting boreholes, hand-held, was impressive. I hope you find ways of keeping it cool (white cloth cover, leaving the connector ports open, thin copper tape on the card/heatsink, whatever you have to do). Take care, and thank you :)

Demo Dave!! I have recently been introduced to something called "Auto Stem" and I was wondering what you thought of them. Apparently they are not HE, but rather low order stuff. I read that the dets are nitrocellulose. They explode in a lot different manner. There is not a huge overpressure and the dets sound like "THUMPS." They do not require stemming or the like. You simply jam them in the holes. Do you have any thoughts on them?

Fantastic work again there Dave. I notice you're firing off Lead In Line, not your usual Beathoven method. How's that going?

Hope your well now. 👍

Hay nice job Dave from madmax Melbourne 👍👍👍👍👍👍👍🤪🤪🤪🤪🤩🤩🤩😊

Dave, do you mix your own anfo or does it come premixed?

I can't even comprehend what it must cost to build there!

Hi Dave ☺ I guess that's an expensive way of trenching, good job you had a drilling rig. Thanks for another interesting video mate, and I hope you've got over the covid bug ok. Best wishes to you and your's, Stuart UK.

Considering you have a magnet on a string... do you attach a small neodymium magnet (super glue or tape) on those items prone to finding the hole to make them easier to fish out?

G'day Dave, Upper gully Lou here. I would like locations annouced at beginning of videos if thats ok

Is there a market for the broken rock or is left on-site?

Fans and air conditioners, heh.

Do you bring in fresh soil for every shot or is it screened and reused?

Are thumbs on excavators uncommon in Australia? I don't think I've never seen one...

So what happens if you do find unexploded charges?

Run out of rock, kind of good ⚡️

Is it the emulsion that gets ruined or the anfo? Both?

Boom Boom👍👍👍 Would some of your stronger blasts, like the 25 hole shot one, show up on Melbourne's Seismometer?

why dont you use rubber mats over the holes? isnt it more annoying to keep filling over the holes then having you digg it avay?

They might be missing person there Dave?

i remember we were doing a road through hard stone an were putting nearly a hundred weight of powder in each round the shot was only 2.4 meters deep an the road was 15 bye 12 ft arches

Dave, what were the black and white birds that flew away when you touched off the 25 hole shot? Thanks for sharing this round of blasting. I with you on the jail time, but most likely they will fade away with millions stuffing their pockets.

Are you ok now ???

Dave it's been a month hope all is well!

What happens to the rock that gets extracted?

My question is, how how did the polaroid photos get in the hole with the granite?

9:46 No thumb on the excavator?

I like the use of what look like kids traffic cones for funnels and the fact that all the bits of rubbish go down the hole, Is the white powder you pour down on top of the knockwurst on a string more anfo? Apart from obvious flying material does the covering of earth improve the blast?, I feel like it holds it down and forces it back into the rock a bit? Also I can't help wondering what it would be like to sit on top of that lot on a plywood board....I have a feeling it would break bones and do all sorts of damage to internal organs ....so probably the dumbest idea ever but you know sometimes the thought just kinda .....well knowledge is knowledge right

I would make it to my first job, when deciding on how much boom, my answer would be “all of it”….

what an odd find on the rock

Looks like a pipeline tranche going through

I'm not sayin' it's aliens, but ...

So, not virgin rock?

Hi there that puff of dust at 18:35 was that a light cover bang

Why don't any of the excavators have a thumb attached? It would be easier to pick up them rocks .
