Greetings once again from North Kachin State, Burma. We have been working on 200km of road for the last 7 years, operating only during the 4 month dry seasons. I've had everybody watch your videos. This season our choices of demo are limited to 1960s manufactured US Army composition B and C4, and lots of det cord that comes packed in #10 coffee cans. No detonators, so each hole has a length of det cord with an Ulli knot at the end. To initiate the shot the end of the det cord is run down the muzzle of an AK-47 and stuffed into a chambered cartridge with bullet removed...crude but it works. Due to the Burmese military takeover the economy is trashed; diesel and gasoline are running USD $25/gallon. Any motorfuel has to come 350km up the road from Myitkyinaa. What this means is that we cannot use any heavy equipment. Anyway, this video was eagerly devoured, as it shows a hint of how much calculation and planning you must do before every shot, and before that, the survey and planning needed before you even unpack any tools. With all of your equipment and material it's indeed possible for just one man to get rocks broken. Currently we have 50+ men and women on site moving dirt, drilling using a 16lb sledgehammer and drill pike, cutting and molding demo.
Oh.... I will never complain again. I think that just one petrol powered "Cobra" 2 stroke rock drill could change lives. At least you have some C4, that does a pretty good number on just about everything.
The equipment operator is very good.... he expertly sifts soil from blasted rock while making piles. He also applies soil cover over your loaded and wired shots very gingerly so as to not knock any connections loose.
Another expertly planned and executed shot in tight conditions! Your layout and sequences were obviously from your blasting experience controlling vibrations in tight conditions. Thanks for taking us along. Dave
Brilliant video Dave, succinct and full of interest. So many content creators have vied for our viewing time over the holiday period with huge hour plus vids and to be honest they get skimmed because we have other creators material to view too. Yours never give the impression you are chasing the viewing figures on the algorithm. I hope you've had a great Christmas with your family and friends. Regards from Scotland.
Dave that was the perfect video to blast your way into 2024! Happy new year and thanks for sharing you work adventures! Alway a great day when you post! Oh, I also have a story in regards to not using a witness tube! That why I once asked what you do if you find a shock tub that live!
I don’t remember you dashing about doing what appears to be collecting the blasting wire. I grew up in the 1940-1950 era, I have watched many blasting operations, having grown up on top of a granite mountain, and I distinctly remember the joy of my young life in collecting many miles of wire. It was hair thin, and I never had a single use for it, but I cherished it!
I can feel more relaxed watching, Dave, when an excavator mounted drill is doing most of the hard yakka! When you are using those horrendous hand-held jack hammer type do-dads, I can feel, in proxy, every jarring jolt your frame is subjected to! That's an impressive pile of broken granite from just one house lot!
Huge rocky landscape - big job for sure - hard to see much other than rock!! Good you had the drill rig. Nice work Dave, as usual - plenty more to go! :)
Good morning from Pennsylvania USA! I was so excited when I first saw the site in the video, I thought oh yeah uncovered shots! No luck! Either way that's alot of rock to remove! Happy New Year!
No such luck... and the bad news is that historically most of my uncovered shots were for the logging industry and the logging industry officially end here today, killed by the Greens.
oh i was hoping for open shots it's been a minute since you had some! a sorting bucket around here they call those rock buckets!! well at least this job is easy on the back drilling wise!!
The blaster master booms again. Interesting block which raises a Frank Lloyd Wright question on whether a house should be designed around the site or the site shaped around what is going to be a square level house (ho hum). Fallingwater, Mill Run, Pennsylvania could have been a starting point, although you'd have missed out on some work Dave. Happy New Year
Hi Dave, damn you made mince out of that granite. Super effective blasting and no mud! Just want to say a sincere thank you for all the time and effort you put into your videos. It really is a fascinating science. Take care, enjoy a break and looking forward to your antics in the new year.
Thanks Dave great vid , using the rig def seems the way to go easier watching you sitting rather than having to straddle the drill . Have a great and prosperus New Year .
It is easier, you will be seeing more of it, not much use in the last year as my tilt tray truck had a broken gearbox and it took a while to get a part made for it.
Happy New Year Dave! Glad to see you got the drill on site for that job....definitely nice to drill the easy way once in a while! 🍻 Hope the new year brings you and your family good health, luck, and happiness!
@@demolitiondavedrillandblastAnything to save the wear and tear on your body Dave! You might have to look at a 4x4 truck with loading ramps and room for your compressor, hoses and tools.

Love watching your vids. I used to do a lot of residential, close in blasting in Canada. What really strikes me is the dust suppression. I wish we had done it this way, although I can tell it would be a lot more work, it would keep the customers and neighbours much sweeter, and it just looks like a cleaner jobsite than the disasters I used to oversee. Is this because of regulations in Australia or just professional pride? What I wonder is why you so often use dirt for cover instead of matting? Is it so you don't have to bring in larger excavators? i used to use mainly 10,000lb rubber matts in the city, and it worked great, never had fly problems. The only fly we had was if we allowed the excavator operator to let material accumulate on the topside of the matts. Gotta shake them and keep them clean.
Hi thanks for watching and contributing. I try really hard to manage the dust, not just because of the huge mess that it creates but primarily because most of the rock that I get to drill has a high crystalline silica content - which makes it very dangerous. Thankfully there are now regulations that cover this in Australia, I have been ahead of best practice for about 20 years now and I'm sure this has saved my lungs from a lot of damage. Mats - I have a heap of blast mats, but I need to bring them to the job on a truck which costs money, the soil is already there and I can do much bigger shots than I would if I only used blast mats. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need. Another bonus of using soil is that I no longer spend my weekends repairing blast mats. Yeah... putting heavy items like upturned wheel barrows etc. on top of blast mats has surprised a few people hahahahah!
This is a common problem here in Maine where the solid granite 'ledge' is everywhere, just 18"-24" below the surface. The blasters drilled right through the existing cover and set charges , instead of exposing, drilling and then covering after loading. A single blast of a 40' by 80' hole for basement foundation. And yes, I have a video !
Yes, that is the best way to do it when you know there is rock there. So many times I tell people to leave the soil on and we bring the big drill... but no... they want to have a go at it... and they fail and it cost them a lot more in the long run.
G’day Dave. Happy new year to you mate. Just wondering, watching you drill those holes. If they can use water jets at ~50,000psi to cut stainless steel and other stuff, could you use a cutting head, similar to a Kärcher ‘spinning’ head, to cut the holes, with a pipe vacuuming up the rock/water slurry? Be a whole lot quieter, maybe.
You also need to power the machine providing the water jet pressure as well as having a water supply on hand. Whilst not quite as powerful as what you are suggesting, those NDD Non Destructive Digging trucks with the tank, vacuum and water supply, (a) cost @ $500,000 and (b) make quite a racket by themselves, (c) they have to make frequent visits to authorised disposal centres to get rid of the water/slurry mix (d) the trucks plus one or two operators cost around $300 per hour plus travel time. Mark from Melbourne Australia 🇦🇺
@@markfryer9880 thanks for the info, Mark. I’ve done a job here on the farm cutting a trench ~50cm deep about 25m across the ‘lawn’ (a small paddock in front of the house). We used my Kärcher with the ‘twizzy’ nozzle, and then my wet’n’dry vacuum with a pair of 20l plastic tubs set in the line to a piece of 50mm white PVC pipe (it was to fit a 40mm rural poly-pipe). We got good’n dirty 😄, but at the end, just poured the muck back in the slot, and it was almost invisible in a week.
How well can you determine the size of the pieces left after a blast, ie can you make smaller or larger pieces by altering the hole depth, spacing, and size of load on each hole?
Can you explain your reference to "Control Row and Echelon Fashion"? I'm assuming that this is a hole firing sequence, but I don;t know what the options for firing order are and why one would use one ordering or another. Is it to maximize rock breakage? Minimize rock throw? Something else?
OK... I thought to my self that this answer will take a while to formulate and carefully explain and it is a bit hard to do without a white board. Idea - get ChatGPT to come up with something! It did a reasonable job apart from missing one very important point, that if you has a surface delay clip failure at any point the which results in some holes not firing, you do not get all of the rows of holes behind the failed holes firing, as would be the case in old style "train track" hook up method. This makes sorting out the misfire and making it safe a lot easier. Chat GPT said - The "Control Row and Echelon" blasting hook-up method is a sophisticated approach employed in the field of explosive engineering for controlled and efficient rock fragmentation in mining or construction operations. This method strategically arranges explosive charges in rows, with a central control row flanked by echelons on either side. From a timing perspective, the control row plays a crucial role in initiating the blast sequence. By carefully sequencing the detonation of charges in the control row, the blast can be precisely controlled to optimize fragmentation and minimize undesirable effects such as ground vibrations. This sequential initiation allows for a more uniform and predictable breakage of rock, contributing to enhanced safety and efficiency in excavation processes. The echelons, positioned on either side of the control row, serve to further refine the blast's effectiveness. These secondary rows of charges assist in shaping the blast pattern and ensuring a controlled release of energy. The staggered arrangement of the echelons helps distribute the force of the explosion more evenly, reducing the risk of flyrock and enhancing the overall safety of the blasting operation. One of the notable advantages of the "Control Row and Echelon" method is its effectiveness in minimizing misfires. Misfires, where explosive charges fail to detonate as intended, can lead to operational delays and safety concerns. By incorporating a systematic initiation sequence and redundancy through the echelons, this method significantly reduces the likelihood of misfires, providing a reliable and secure blasting solution. In summary, the "Control Row and Echelon" blasting hook-up method stands out for its precision in timing, controlled fragmentation, and misfire minimization. This approach reflects the commitment to safety and efficiency in explosive engineering applications, making it a preferred choice in various industries reliant on controlled blasting for rock excavation.
Been there, done that for years Robert, I have a heap of blast mats, but I need to bring them to the job on a truck which costs money, the soil is already there and I can do much bigger shots than I would if I only used blast mats. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need. Another bonus of using soil is that I no longer spend my weekends repairing blast mats.
Good show, Dave!! Do you know what methods the previous contractor employed to break the rock they managed to break? Whatever they did obviously paled in comparison to your method.
The trees Picked a nice place to grow. Is there water there? Depth? or are they going to hook up to a community water system??. Looks like a nice job, I am jealous,,,,,,,,,,,,,,

Hey Dave, Great end of the year video, Always a pleasure to watch. I have to ask, Did you or your Family sufer any damage from the recent Tornado's that was there in Austrailia. My friend Cara Bidsmend she lives in New South Wales had a lot of damage on her ranch there. Trees down, power poles and power lines down and such , She has Barns with damage and lost some of her animals too. She has been without power now for 7 days. Looked like Florida when we had our Hurricane this past year. A lot of distruction, injures and some deaths. Well Dave I hope you have a very Happy New Year and We all have a better year in 2024. Thanks for all you share .
Dave, I've always enjoyed your videos. While watching you drill the 48 holes for the first shot in this one, I got to wondering, What is the largest number of holes you've shot at one time? What were the circumstances , and did it go as planned ?
The biggest number of holes in one shot was 253, numerous shots over 200 holes, limiting factor is often how many I can load and hook up in a day. All good. Here it is - ua-cam.com/video/0oyX5MUh1bg/v-deo.htmlsi=DeQiGo9IsI7jtukA&t=50
@@demolitiondavedrillandblast awesome I love seeing creativity and ingenuity at its finest, and what you can build something for can be 1/10th of the price and work just as good
The "I'll tell you that story sometime", must have been a very scary day. I'm guessing a shock tube got compromised, meaning a row/hole didn't go off and you ended up digging through a live & loaded hole....
That is one very rocky site... do buyers get a discount for sites needing extensive blasting before they can build ... ? Cheers Mate... 2024 around the corner.
Cool to see If you do it as i would have, based on The overview of The site. That excadrill is nice over The Atlas. Get a commando🤫 What was your holespacing?
The drill mast is home made for me by my friend Mike, the hammer is an Atlas Copco BBD94 also known as a Panther. Commando's cost an awful lot of $$$ here. Close hole spacing - 700mm - had to keep the charge mass very conservative as the neighbors were not very happy about the whole concept.

This is not wire but plastic signal tube. The days of the old electric dets are all but over, these ones have a few safety benefits.
Still, I loved my electric dets for residential work. Can always check circuit, and really cheap compared to the nonels.@@demolitiondavedrillandblast

... and please do tell us the "long story" about Shock Tube/Witness Tubes ... 🥸
OK... I thought to my self that this answer will take a while to formulate and carefully explain and it is a bit hard to do without a white board. Idea - get ChatGPT to come up with something! It did a reasonable job apart from missing one very important point, that if you has a surface delay clip failure at any point the which results in some holes not firing, you do not get all of the rows of holes behind the failed holes firing, as would be the case in old style "train track" hook up method. This makes sorting out the misfire and making it safe a lot easier. Chat GPT said - The "Control Row and Echelon" blasting hook-up method is a sophisticated approach employed in the field of explosive engineering for controlled and efficient rock fragmentation in mining or construction operations. This method strategically arranges explosive charges in rows, with a central control row flanked by echelons on either side.
From a timing perspective, the control row plays a crucial role in initiating the blast sequence. By carefully sequencing the detonation of charges in the control row, the blast can be precisely controlled to optimize fragmentation and minimize undesirable effects such as ground vibrations. This sequential initiation allows for a more uniform and predictable breakage of rock, contributing to enhanced safety and efficiency in excavation processes.
The echelons, positioned on either side of the control row, serve to further refine the blast's effectiveness. These secondary rows of charges assist in shaping the blast pattern and ensuring a controlled release of energy. The staggered arrangement of the echelons helps distribute the force of the explosion more evenly, reducing the risk of flyrock and enhancing the overall safety of the blasting operation.
One of the notable advantages of the "Control Row and Echelon" method is its effectiveness in minimizing misfires. Misfires, where explosive charges fail to detonate as intended, can lead to operational delays and safety concerns. By incorporating a systematic initiation sequence and redundancy through the echelons, this method significantly reduces the likelihood of misfires, providing a reliable and secure blasting solution.
In summary, the "Control Row and Echelon" blasting hook-up method stands out for its precision in timing, controlled fragmentation, and misfire minimization. This approach reflects the commitment to safety and efficiency in explosive engineering applications, making it a preferred choice in various industries reliant on controlled blasting for rock excavation.
.. and please do tell us the "long story" about Shock Tube/Witness Tubes ... Another day.
Happy new year, was wondering why you don't use rubber blasting mats? Seems it would be more efficient time wise.
Been there, done that for years Robert, I have a heap of blast mats, but I need to bring them to the job on a truck which costs money, the soil is already there and I can do much bigger shots than I would if I only used blast mats. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need. Another bonus of using soil is that I no longer spend my weekends repairing blast mats.
Good show, Dave!! Do you know what methods the previous contractor employed to break the rock they managed to break? Whatever they did obviously paled in comparison to your method.
The previous guy did some work with a hand drill some time ago.
After to see your videos, also I use the blue to mark the holes, always there are something to learn .. lol
Glad you like the blue paint, I count them as I paint them, helps me not count any twice.
Gathering the spent det-cord.
Is that required or just something you do?
Not det cord as the det cord all explodes, this is plastic signal tube, yes, legal requirement, littering issue, not dangerous.
Dave what are you picking up from the rocks
Used plastic signal tube and surface delay clips.
Happy New Year and thanks for sharing. Do contractors ever bring a rock crusher on site? or is it always hauled away?
It is usually hauled away, sometimes goes to a crusher, sometimes other uses.
The trees Picked a nice place to grow. Is there water there? Depth? or are they going to hook up to a community water system??. Looks like a nice job, I am jealous,,,,,,,,,,,,,,
I would think that there is town water available on tap here.
@@demolitiondavedrillandblast Where I am at, but in town water they require at least 1 part per mil. Floride, and they add1 of any number of things as a disinfectant. In town here its Clorine, elsewhere. potassium permanganate, u.v. light, pressurized filtration to less than 1 micron to remove giardia, and it goes on and on. And me, where I am at? Private well, very hard water, about 100 feet down, and I live in a desert, prehistoric lake bed, annual rainfall in 12 to 15 " rain per year. If we donr put water on plants they die, crumble to dust and blow away. My well water is delish, very hard.... i use a sand filter.is all... If you want mountain spring water its drive into the hills.. we have to be careful of giardia, but in places we are free to drink directly out of mountain springs.. as long as bear, grizzly, cougar, elk , deer, birds .... and wolves dont poop directly in it.......... and aliens , cant forget them.........
What is being done with the boulders and stone from the blasting?
Not sure where this lot went Timo.
Hey Dave, Great end of the year video, Always a pleasure to watch.
I have to ask, Did you or your Family sufer any damage from the recent Tornado's that was there in Austrailia. My friend Cara Bidsmend she lives in New South Wales had a lot of damage on her ranch there. Trees down, power poles and power lines down and such , She has Barns with damage and lost some of her animals too. She has been without power now for 7 days. Looked like Florida when we had our Hurricane this past year. A lot of distruction, injures and some deaths.
Well Dave I hope you have a very Happy New Year and We all have a better year in 2024. Thanks for all you share .
We were fine here Rich, that was a long way from us. we are having unusually cold and wet weather hear but no tornado's
@@demolitiondavedrillandblast Glad to hear that.
MM77 Approved 👍🏼👍🏼……………………………………………………………. At least this time you are not right on top of the neighbors house! LOL
Yes, that is a relief for a change.
Great job as always. What the hell they do with all that rock!!!
They were taking it somewhere...
thanks dave
Thanks for watching and contributing Leon.
462 👍's up demolition Dave the most explosive man on UA-cam
You were a bit slow on this one Scott.
Dave, I've always enjoyed your videos. While watching you drill the 48 holes for the first shot in this one, I got to wondering, What is the largest number of holes you've shot at one time? What were the circumstances , and did it go as planned ?
The biggest number of holes in one shot was 253, numerous shots over 200 holes, limiting factor is often how many I can load and hook up in a day. All good. Here it is - ua-cam.com/video/0oyX5MUh1bg/v-deo.htmlsi=DeQiGo9IsI7jtukA&t=50
Looks expensive. Is that a weeks worth of work to prep a site for foundation? Nice video
4 days on this job.
Do you own a crusher?
Is the rock taken away as rubbish or sold for landscaping purposes 🇬🇧
It is almost always used somewhere.
G’day Dave, is the excavator drill your machine???
Sure is, my gunsmith friend designed and fabricated it for me 18 years ago, drilled a lot of holes this one!
@@demolitiondavedrillandblast awesome I love seeing creativity and ingenuity at its finest, and what you can build something for can be 1/10th of the price and work just as good
Great video Dave that is a lot of rock. What do they do with it after you get done?
I don't know where this lot is going.
Now can a contractor have that stone ground up and use it for the driveway for the house construction?
Certainly!
Happy New Year.
Likewise from the "Land Down Under"
Will we see 👀 🤔 any Road Jobs next Year ???
I don't see any forest road jobs Alfred as The logging industry has now officially finished and they were the largest customer for these jobs.
The "I'll tell you that story sometime", must have been a very scary day. I'm guessing a shock tube got compromised, meaning a row/hole didn't go off and you ended up digging through a live & loaded hole....
Ah. This video brightened up my miserable Saturday morning. No wonder the forefathers buggered off from Europe. Its mizz in December
Not that much better here just now... I have the heating on!
That is one very rocky site... do buyers get a discount for sites needing extensive blasting before they can build ... ? Cheers Mate... 2024 around the corner.
No chance of that.
Cool to see If you do it as i would have, based on The overview of The site. That excadrill is nice over The Atlas. Get a commando🤫 What was your holespacing?
The drill mast is home made for me by my friend Mike, the hammer is an Atlas Copco BBD94 also known as a Panther. Commando's cost an awful lot of $$$ here. Close hole spacing - 700mm - had to keep the charge mass very conservative as the neighbors were not very happy about the whole concept.
@@demolitiondavedrillandblast And granite moves If you overcook it. We have endless supply of hard af granite. That pile of dirt seems wild, as We mainly use tiremats here in Finland. You have mad skills.
I suspect you didn't miss hand drilling all of those holes.
I think you might be on the money there Tom.
First blast, 🔥 That bucket cant last long, with granite that hard.😅
You are correct!
The way that rock has broken up suggests it is hard but brittle. Give it a decent whack and it cracks up.
Very brittle.
You should do this with your cracking goo....
much higher cost.
shucks, I was expecting "no cover" shots out there in the middle of nowhere
There were homes both sides unfortunately.
Nice rocks to build Walls.
Yes, and plenty of it Alex.
Like aways , blasted into nuggets.
You are lucky to get a great digger operator.
To bad that your digger is not enclosed.
Dust free
Cool
Less noise
Thanks for watching and contributing Lex.
They would want to have got that block cheap.
👍👍
All l see is Cha Ching!!!!
😉
No cheap blocks in this area my friend.
They've got plenty of material for rock walls now.
More than they need I think.
why dig down - instead build up and on granite, avoid any moisture issues - the only holes i would drill would be for rebar
