Fast and efficient Granite removal on a very rocky home site. 

Oh yeah, I can churn them out when I get a few days off.

Interesting that the AK barrel survives that! Sorry to hear your troubles...

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.

Yes, very surprising that the AK barrel survives, I know that you should never try to unblock drill steels with red cord as they "don't make it".

Thanks

It's nice to find a good one.

@@demolitiondavedrillandblastdon't forget that goes for you too! I'm sure plenty of folks have said the same thing about your work.

Thanks, you too!

Thanks for tuning in and contributing LLD. I also struggle with Hour + videos.

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

Me too!

You got that right Jim, have a good one.

I guess I got my years mixed up, the Nixie tubes had me confused, old and newer mixed up, love the old TTL devices.

Oh, it is that easy with the machine David.

I would love to use that but it is copyright protected.

Your welcome Lou.

Thanks for watching and contributing David.

Thanks

Thanks William, you will have to share your experience with me, email me if you don't want to detail it here. - Dave at demolitiondave dot com dot au

Greeting to you also.

More leg over coming soon...

going to have a rock solid foundation

Hello there! Thanks for stopping by.

Thank you very much!

Likewise from the "Land Down Under".

Fixed it right up.

The hand drill is not so bad when you are conditioned to it, This job is only ~ 33% done.

Hey, thanks for dropping in Max.

Thanks Lee.

Same to you, thanks for watching.

Not sure when this will be Alex.

Oh yeah!

I hear you Bruce.

Good to have an easier job for a change Keith.

Thanks Kevin.

They all want easy digging, if is not they have a tantrum sometimes.

You got it Bill.

You were a bit slow on this one Scott.

Thanks Jim.

Yes, that is a relief for a change.

It was.

Not that much better here just now... I have the heating on!

Glad you like the blue paint, I count them as I paint them, helps me not count any twice.

They had a fair bit stacked up on the site from ages ago when they first did the cut.

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.

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.

A lot of truck loads have already gone before the video started.

Thanks for watching and contributing Leon.

Glad you enjoyed it MLE.

Oh.. it is not new Chris just has not been out to a job in a while because my truck had a dead gearbox. Thanks for watching and contributing.

I often ask myself the same question.

Thanks for watching and contributing Paul.

Yep, back on the rocks on January 2nd.

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!

Thanks, you too!

3 1/2 days.

Busy long days , hope you are having a break from it around now. @@demolitiondavedrillandblast

Good spotting. Thanks for tuning in.

Often the homes do get a redesign when a lot of rock is encountered David.

ok nice !!!@@bottomlands

Thanks Cosmo, best wishes to you and your family also.

No chance of that.

This machine is mine, probably does not get as much use as it could.

​@@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. Mount as much equipment as you can on the drill rig to save set up and pack up time. Happy New Year to you and your family Dave! Mark from Melbourne Australia 🇦🇺

Thanks again.

No cheap blocks in this area my friend.

Not det cord as the det cord all explodes, this is plastic signal tube, yes, legal requirement, littering issue, not dangerous.

Yes, and plenty of it Alex.

Likewise from the "Land Down Under"

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.........

The previous guy did some work with a hand drill some time ago.

More often than not it gets used somewhere.

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.

Thanks Mark.

@@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.

They were taking it somewhere...

Yes, 100%

This one is in a fairly pricey area and it is a few acres... probably close to AU$1,000,000

Used plastic signal tube and surface delay clips.

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.

I think you might be on the money there Tom.

... 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.

Thanks for watching and contributing Lex.

Certainly!

Yes, the Orange is attached to the down hole detonator and the pink is attached to the surface delay clip.

@@demolitiondavedrillandblast Neat, thanks for the explanation!

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.

@@demolitiondavedrillandblast What I like is how the grade raised up showing how effective the charge was. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hLub9O3-_oU.html

It is almost always used somewhere.

much higher cost.

You are correct!

Not sure where this lot went Timo.

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.

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 - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0oyX5MUh1bg.htmlsi=DeQiGo9IsI7jtukA&t=50

It is usually hauled away, sometimes goes to a crusher, sometimes other uses.

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.

Correct.

There were homes both sides unfortunately.

4 days on this job.

Do you own a crusher?

More than they need I think.

A lot like being married...

Very brittle.

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.
