how can anyone not like this, so much work goes into the video setup to get a great view of the action and tons more goes into the blasting setup. I guess you can't please them all.
I'm sure that one of my competitors is subscribed and hits the unlike button as soon as he sees it. Often the is a unlike in the first few min of posting.
I have really started to enjoy my retirement mornings with a cuppa and a few of your videos. Starts my day off with a bang! My cat seems to enjoy watching the ground heave with each blast too. Cheers!
I’ll have to setup an account for Mischief, but my guess is he’ll only be interested in cat videos then. 🤔. FWIW he does really perk up when there’s shots with no overburden. Must be the shrapnel cascades that get him riled up. Play safe out there Sir.
Totally logical to blast - if only to weaken for a breaker to finish (even that was hard work). As always, a real treat to see relatively minimal stemming and so a delicious display of fly rock :) Satisfying to say the least... nice example of sequential delays. Slo-mo's were excellent. Amazing how the end series suffered so much from stemming being shot out. This will be a pretty expensive trench! Heck of a lot of drilling needed though first on the whole line... tiring! Looks like there are some spring storms around.
Thanks for tuning in again, about 3 hours hard drilling here, using the newest hammer and new drill heads, yes weather was very unstable, are you on Facebook Chris?
Hi Dave [- yes, on FB but not all that much - mainly staying in touch with a few friends and family. I use a pseudonym and am there as Chris Wayne. Drop me an invite sometime.
Glad to enjoyed it Andrew, nothing like a "self extracting" shot! by the way, she who must be obeyed has tentatively approved the purchase of a Kronos 2.1 camera!!!
Very educational. I understand that when trenching , the key is to use the preceding blast hole to provide exit for the next hole. I know you sometimes place pea gravel(?) above the charge - presumably to hold down the blast long enough to build enough pressure , but I didn't see a lot of that this time 'round. I did notice that you drilled at an angle to try to get a better lift. When done without cover this is very exciting !
It sure is a lot different without cover! The shot was a dud first time around as not far in, a hole vented a lot of it's energy into a horizontal joint in the rock and because it did not fully break out, the following holes ejected because the burden was too great. The shot was a bit high risk for failing as the stemming length was short and I really should have drilled the holes in a zig zag pattern. A single strait line of holes works a treat in softer rock and often works OK in Granite... this time it did not. Thanks for watching.
Very satisfying. Some controlled mayhem for a change. I’m really surprised at how much the covering contains the blast. Nice to see the firing sequence as well. Yes that was a good one.
Hello, I used to drill and shoot ditch line and road cuts in the mountains of Colorado back in the 1960s. We used 40% dynamite and nitrates with delay caps, 50 holes at a time. One thing we did do was leave room in the holes for tamped in top cover. We got less blow out of the holes, most of the time. Enjoy your videos, keep them coming!
Thanks for your input Bill, I did use the best stemming material available, that being 5mm sharp aggregate, but when only one hole fails to move the rock then the burden is far to great for successive holes and they all blow the stemming. Thanks for watching Bill
Excellent job! It's amazing how a bucket of chemicals has enough stored energy to throw the earth like that. You should show us the types of explosives you use for various applications. I'm curious to see the particulars of shock tube and how all that stuff works.
Dave, the uncovered shots are the best. I just finished watching the massive stump get stolen from the woods and then I get treated to this, great fun. Love your videos and keep them coming. Cheers, Basil !!
Looks like you may have hit a horizontal joint most of a meter down. The second set of camera shots show the central piece lifting a small bit in a "heave". thus blast energy was dissipated horizontally. The breaker did the trick though. Trench blasts are always fun, especially if you get some distance and they can 'zipper'. Great video and keep up the good work.
The main East-West fibre optic cable was dug in along the boundary of the farm I work on in Western Australia, however the line ran through a number of large exposed Granite rocks between 50 and 150 metres across. They gave up trying to dig them in and just laid them on top of the rock and heaped up stones on top of the line!
They just laid huge charges on top of the rock???? Wow, that is so inefficient and so so so so so loud.... and then they put stones on top...No... they didn't did they?
Sorry Dave, I meant they just laid the cable on top of the rock and piled rocks on top of the cable. It was supposed to be buried 2m deep, so they piled 2m of rock on top of the cable! There must have been kilometres of super hard Granite in our district alone and it was being ripped in with a D10 being pulled by another D10, which while it was an impressive sight, it was never going to go 2m deep in Granite!
Thanks Murphy, The sound for both the drone and the DJI Osmo camera that is used for the slow motion all come from the Sony Handicam, I stretch it to suit.
Excellent. What a luxury not having to cover that shot. From what I understand one of the many liabilities in blasting is the fly rock if it gets away from the shot and hits someone or something, and you always do a great job of covering that. On the other hand the basic escape velocity from earth is supposed to be about 24000 miles a hour , plus there are variables like air density, etc. , Some unnamed government placed a steel manhole cover over a deep hole while testing deep underground nuclear bombs., and yes it was actually launched that steel cover rather rapidly, but they couldnt tell if it made it into orbit.....Its a pleasure watching your videos................
I worked on a house in North Wilmington, Delaware that was on a granite cap. They blasted to make a swimming pool, too deep. Anyway, we were barely aware when they detonated as they buried each set up under about 3 tons of dirt. Fun stuff to watch.
This was very cool ,it looked like the mining operation here in the states(out west anyways) but on a smaller scale. Still a ton of fun to watch, nothing better than this to go with morning coffee.
I lolled out loud when you said "it won't be because I didn't put enough explosives in" without telling us how much you HAD put in. Rock IS going to move! Just wasn't the direction you hoped... Lol And you can also see in the slow mo of the first shot why delays in the detonators is so important, as the blast tube gets decimated by the adjacent charges. Also, loved the old detonator!
@@demolitiondavedrillandblast We need a video on what happens inside the mysterious explody machine when you push the T-bar down. The internet needs to know.
@@AndrewSmith-ir1ui There is such a video. I don't know if it's from Tom Scott, or Technology Connections, or Today I Found Out, or Practical Engineer, but it's from one of those or one like it.

You sure know how to make hard rock Jump to your tune. That some "HARD GRANITE" there. Two shots and still one section wont give in. LOL - it saying "You wont brake Me Mate!" Good job and nice video, thanks for shooting us along. Safe Day.
Bloody Hell, Mate! That was a pretty good pop!You could see the whole rock shelf lift up, right where the unbroken bit was. I expect you don't look around when you're working, I know I don't, but that was a truly beautiful place
at 2:51 you can see the charges being thrown. 41 holes, 20 failures. so 20 holes is all you have the speed for? Is there a way to wire 20 or 21 holes from each end to the middle? This truly has me curious.
The rock country in central Texas is much like this. Just under the soil and you'll hit granite when digging. There's a lot of work in laying utilities or searching for water....a lot of hard work.

Very very cool 😎 Your camera work keeps getting better and better, Dave! This was really a doozy of a blast!💥 Looks expensive. In the US a rural job like this would have been ran above ground. Thank as always for the cool videos 👍
@@demolitiondavedrillandblast A former work colleague has a place in rural VIC, and he told me that after the Black Saturday bushfires the power authorities decided that overhead lines were too risky, and forced him and his neighbours to re-route their electricity underground.
@@demolitiondavedrillandblast My colleague and his neighbours didn't like it at the time - they had to pay for it themselves; and the Authority imposed a deadline for the work, after which the overhead lines would be decommissioned: in other words, "Do it by date X or lose your electricity!" A power engineer once told me that underground high voltage lines can cost up to 20 times that of overhead lines. But that installation cost would pale into insignificance when compared to the cost arising from a bushfire.
Sure scattered the rock in the farmers field. Just pasture though? No need to gather it all up? Two blasts in the same holes and the hydraulic hammer still had problems until he started from the outer edge, working back. Great effect, seeing what is often buried. Had to watch more than once.
@@demolitiondavedrillandblast we would have problem with differeng types of sandstone when tunneling. Just because, you load it the same each time does not mean you get the same result each time. You just deal with it and hope the next blast went better.
Back in the days before all the Nanny State restrictions I paid a social visit to a cocky mate in the Mallee while he happened to be preparing to blow some openings in limestone caprock over soft loamy substrate in order to plant some shade trees for his sheep. He was using ANFO but had prepared holes better suited to receiving fence posts than charges of low explosive. This piqued my curiosity so I asked him what he planned to use as kickers for such substantial volumes of low yield material which by my estimation, probably approximated two kilo's of loosely packed ANFO per hole. His reply was to open an old battered biscuit tin lying in the tray of his ute and display the contents which comprised about four sticks of sweaty gelignite. I was beginning to feel distinctly apprehensive as I nervously observed that he didn't have enough sticks for the number of holes he had prepared. I should have known better by that point because his immediate and unhesitating response was to grasp a stick of Gelignite between both hands and break it with a sound like a green stick being broken. At that point I virtually teleported the five hundred yards or so to his implement shed where I remained in the dubious shelter near a combine harvester for the rest of the morbidly fascinating horror show. From that point on he responded to my shouted admonitions for caution by shouting back all manner of derogatory taunts regarding my courage, manhood and gender etc. As a grand finale his effort barely made an impression on nature for which I for one was profoundly relieved.
Yes, back in the days before the planes hit the buildings, any farmer could just front up and buy explosives on the grounds that he was a primary producer... and AN was the fertiliser of choice, something you ordered by the truck load and they dumped in the paddock, how the world has changed. As for the sweaty sticks, despite being not as sensitive as folklore might suggest, rough handling is not a good idea. What you have to watch out for is when the exudation has crystalised, this is real bad as because the crystals are relatively hard and sharp, when moved, very high localised point loading can occur and cause an unplanned detonation.
Well Dave, I haven't seen anything that cool since we blew the existing launch pad back at Vandenberg Air Force Base..... 60ft thick, 180ft wide, over 1000ft long. Drilled for MONTHS..... I do wish there was video of it, but back then you'd be hard pressed to find anyone still alive that even remembers.... I don't know if anyone else even cares but that GREAT slo-mo really let's you see how far out in front the charge detonate, and the lag when you can see the gas finally escape...... That's a really cool shot. The difference between delays is real apparent between the two shots. 42ms down to 25ms doesn't sound like much, but man on slo-mo it really stands out....... Anyway like normal THAT SLO-MO IS THE COOLEST THING GOING........ Stay safe mate.......
That is a really big piece of concrete Donn. The surface delay clips lead the in hole detonation by 400ms (the in hole detonator delay period). Hopefully the advertising revenue will soon pay for a Kronos 2.1 supper camera that will do 1080p resolution at 1000 frames per second, current slomo is 240 frames per second with a fair bit of image compression.
@@demolitiondavedrillandblast I can't imagine what a 1000 frames would even look like...... You'd be able too see the flash start to finish going down the tube....... That's going to be a real game changer..... Cheers
I suspect that there was a horizontal fissure just below the bottom of the drill holes, the first hole that did not break properly in the first shot probably broke into this fissure and failed to break and extract as required, In the second shot all of the holes then broke into the void as evidenced by the stemming not blowing out and the whole area lifting up from the gasses filling the void.
i love these uncovered chain blasts

AWESOME video Dave 👍👍
Glad you enjoyed it Bob
Very cool Dave! Great to see a shot "uncovered"!! In the slo-mo vid it almost looks like a train locomotive chugging up a hill!!
Sure does Pat, thanks for watching.
Excellent cinema photography❤
Thanks, did you see the drone take a hit?
The slow mo was like a steam train ,the full speed was a blast .
That was just simply amazing
Thank you so much Tom. please like and subscribe / share
Sure scattered the rock in the farmers field. Just pasture though? No need to gather it all up? Two blasts in the same holes and the hydraulic hammer still had problems until he started from the outer edge, working back. Great effect, seeing what is often buried. Had to watch more than once.
He will gather up all the rock and use it to build his front gate posts. Thanks for watching.
Great video work...you have the coolest job...dangerous, got to know what you're doing for sure
Thanks for watching Cory, not really that dangerous as long as you know what you are doing and do it carefully.
Wow you see the blasting caps first and than the main blast.
The first bit of activity you see is the surface delay clips, these set the timing between holes, the down hole action happens 40mS later.
Some days the rock just doesn't want to play your game huh! 😊
Overall a great show!
Thanks for sharing and take care. 👍 👍
You got that right Ken.
Bummer about the blowout in the bottom of the holes.
It is still a very good video.
👍👍👍
G'day Scruffy
@@Murphyslawfarm did every find any old boats for planters.
@@scruffy6151 Not yet but i am still looking mate
Tell me about it! That's blasting, rocks do not always co-operate.
@@demolitiondavedrillandblast we would have problem with differeng types of sandstone when tunneling. Just because, you load it the same each time does not mean you get the same result each time.
You just deal with it and hope the next blast went better.
Back in the days before all the Nanny State restrictions I paid a social visit to a cocky mate in the Mallee while he happened to be preparing to blow some openings in limestone caprock over soft loamy substrate in order to plant some shade trees for his sheep.
He was using ANFO but had prepared holes better suited to receiving fence posts than charges of low explosive.
This piqued my curiosity so I asked him what he planned to use as kickers for such substantial volumes of low yield material which by my estimation, probably approximated two kilo's of loosely packed ANFO per hole.
His reply was to open an old battered biscuit tin lying in the tray of his ute and display the contents which comprised about four sticks of sweaty gelignite.
I was beginning to feel distinctly apprehensive as I nervously observed that he didn't have enough sticks for the number of holes he had prepared.
I should have known better by that point because his immediate and unhesitating response was to grasp a stick of Gelignite between both hands and break it with a sound like a green stick being broken.
At that point I virtually teleported the five hundred yards or so to his implement shed where I remained in the dubious shelter near a combine harvester for the rest of the morbidly fascinating horror show.
From that point on he responded to my shouted admonitions for caution by shouting back all manner of derogatory taunts regarding my courage, manhood and gender etc.
As a grand finale his effort barely made an impression on nature for which I for one was profoundly relieved.
Yes, back in the days before the planes hit the buildings, any farmer could just front up and buy explosives on the grounds that he was a primary producer... and AN was the fertiliser of choice, something you ordered by the truck load and they dumped in the paddock, how the world has changed. As for the sweaty sticks, despite being not as sensitive as folklore might suggest, rough handling is not a good idea. What you have to watch out for is when the exudation has crystalised, this is real bad as because the crystals are relatively hard and sharp, when moved, very high localised point loading can occur and cause an unplanned detonation.
BLOOO-DYYYY-HEELL, Mate!
Well Dave,
I haven't seen anything that cool since we blew the existing launch pad back at Vandenberg Air Force Base.....
60ft thick, 180ft wide, over 1000ft long. Drilled for MONTHS.....
I do wish there was video of it, but back then you'd be hard pressed to find anyone still alive that even remembers....
I don't know if anyone else even cares but that GREAT slo-mo really let's you see how far out in front the charge detonate, and the lag when you can see the gas finally escape......
That's a really cool shot. The difference between delays is real apparent between the two shots.
42ms down to 25ms doesn't sound like much, but man on slo-mo it really stands out.......
Anyway like normal THAT SLO-MO IS THE COOLEST THING GOING........
Stay safe mate.......
That is a really big piece of concrete Donn. The surface delay clips lead the in hole detonation by 400ms (the in hole detonator delay period). Hopefully the advertising revenue will soon pay for a Kronos 2.1 supper camera that will do 1080p resolution at 1000 frames per second, current slomo is 240 frames per second with a fair bit of image compression.
@@demolitiondavedrillandblast
I can't imagine what a 1000 frames would even look like......
You'd be able too see the flash start to finish going down the tube.......
That's going to be a real game changer..... Cheers
Slow motion is really nice, it's not the pieces you see, but the ones you don't that can hurt you.
We were well out of the way KD and ready to duck under the big excavator if necessary.
With the failed blasts does the reload cost the customer or is that on you to bare?
It was on me.
6:07 The entire slab jumps half a metre!......
Good spotting RNZ, that is where a bunch of holes broke through into a horizonal defect in the rock and caused it to lift.
Wait....thats ur boy! Gday mate. Watchin an oldie.
Sure is Jase.
So was there some kind of fissure in the rock there that redirected the blast energy on that one section of the shot?
I suspect that there was a horizontal fissure just below the bottom of the drill holes, the first hole that did not break properly in the first shot probably broke into this fissure and failed to break and extract as required, In the second shot all of the holes then broke into the void as evidenced by the stemming not blowing out and the whole area lifting up from the gasses filling the void.
@@demolitiondavedrillandblast Makes sense, cheers Dave. I always enjoy watching & learning.
love ya work dave ,WOW, have you ever thought about hooking a small seat to that drill ? low mo sounds like a steam train
That is what I thought when first viewed Paul.
Oh man, that was some serious hair-dressing on that rock...great, i looove it
Glad you enjoyed it MM
That four hole location, you can see where the whole slab was lifted up. The whole energy went downwards
Sure can.
Did I notice a change in delays around where it failed?
sure did, started out with 42ms between holes, ran out of them and changed to 25ms.
