Close Proximity Blasting

[@jeffgordon9549]

Gotta love a builder that doesn't think about drainage before building the house!

[@David-if9vi]

I have had this one doing jobs for people. How come there is always money to fix a job afterwards, but never enough to do the job properly in the first place?

[@djdeaf13]

There are several reasons for this. 1. The house appears cheaper on paper for who ever is getting it built, because the drainage isnt included and thoes who is getting the house built dont know any better. 2. Who ever gets the house built dosnt have any more money, they spent it all on the house and desides that the surrounding things like garden, fence, driveway and drainage can wait.

[@alfadoofus]

But it a good thing for the builder to cut out around the rocks for the retaining wall .

[@johnturner4400]

Gotta love a keyboard warrior who can’t comprehend homeowners who have modifications to existing homes that might require the addition of a new drain…

[@davekiernan1]

The greatest secret in WW2 was the proximity fuse. I learned this very well from my spring meister here in Germany. Very important as in the battle of midvay. Fair dinkum Dave.

[@demolitiondavedrillandblast]

The biggest achievement of the proximity fuse was making it to withstand the G forces.

[@davekiernan1]

@@demolitiondavedrillandblast the next big thing Dave was millisecond electronic detanotres from Davey bickford. As soon as it could be fit a microchip in a detonator tube. Like a mobile phone. You can control shockwaves, fragmentation and more. Makes lots of sense, especially with large case blasting. Ie coal and copper.

[@robertgeorgewerner]

Chris G (LetsDig18) has been testing out a little Micro-excavator over in North Carolina, USA. It's very interesting to see how these little machines can be very useful for jobs in tight spaces, etc. Much rather use them than a manual excavator (a shovel). Take care!!! happy Summer.

[@demolitiondavedrillandblast]

Interesting! I'll have to have a look what he has been up to.

Hi Dave. That was a tight one, but successful as always. I still miss those days when you were in forest/jungle and watch the raw power of the explosives unleashed. However, work is work, and we all have bills to pay 😂. Thanks for sharing. It's getting colder here in the UK, whilst it's getting hotter "down under" 😁. Wishing you and yours all the very best.

Dave, Merry Christmas and Happy New Year! I was curious if you ever have used all electric drilling and hydraulic splitting? This job seems like a lot of manual stuff more than usual anyway!

[@demolitiondavedrillandblast]

Electric drills are seriously lagging on the power to weight ratio.

[@jwaterous224]

@@demolitiondavedrillandblast In your experience air line hammers are the only way to go!?

[@TalRohan]

Now theres a thought ..having just wondered what it would be like to sit on a board on top of the backfill. Does the backfill make the shot break up the rock better or not as well as with no backfill and debris flying everywhere? thanks for sharing

[@demolitiondavedrillandblast]

I think it would be a very rough ride. In my observation, the covered shots do not break as well as uncovered, for the same load. The reason for this is that a lot of the energy in the shockwave (compression wave) gets conducted into the surrounding soil, as apposed to an uncovered shot where some of the energy of the shockwave is conducted into the much less dense air (as noise) the energy that is not lost here is reflected back as a tension wave and is available to do more breakage.

[@MostlyInteresting]

But those tiny diggers have been a revolution.

[@Dan_Hall]

How much of that 25mm emulsion stick did you put in the hole? 1/2? 1/4? Do you think even just a little ANFO (1/4 Cup/ hole) might have helped lift the rock up without undue vibration? Thanks!!

[@demolitiondavedrillandblast]

1/4 max ~ 25 grams, ANFO not required.

[@enwri]

How about building a whole substation under existing high tension wires, before finding out the 4x4x6m holes for the new high tension tower footings were in rock not soil. Now THAT person took a risk, don't think they called them "brave" though...

[@rd4660]

Why do you use such large respirators? Wouldn't one of the efficient dust masks suffice?

[@demolitiondavedrillandblast]

Not sure what you mean by "efficient dust mask" - if you mean a surgical mask like everyone wore during COVID, no, they do almost nothing. The Sundtrom SR200 that I use has a P3 or N99 rating - What is P3 Rating? P3 is a respiratory filter rating under the AS/NZS1716 standards for use in Australia and New Zealand. Protects against mechanically and thermally generated particles. Filtration rate: Filters at least 99.95% of airborne particles Suitable for: Relatively small particles generated by mechanical processes eg. grinding, cutting, sanding, drilling, sawing. Sub-micron thermally generated particles e.g. welding fumes, fertilizer and bushfire smoke. Biologically active airborne particles under specified infection control applications e.g. viruses, bactieria, COVID-19, SARS Highly toxic particles e.g. Organophosphate Insecticides, Radionuclides, Asbestos Note: P3 Rating can only be achieved when used with a Full Face Respirator or Powered Air-Purifying Respirator (PAPR). If used with any other respirator, it will only provide filtration protection up to a P2 rating.

[@jaquigreenlees]

if it wasn't a trench I could see using expansion compound instead of blasting.

[@demolitiondavedrillandblast]

I chose to use bangers because it can still be quite difficult to dig out rock that have been broken using the chemical when you only have a small digger.

[@jaquigreenlees]

@@demolitiondavedrillandblast That's what I figured, and the rocks barely being out of the dirt making the chemical less effective as well. hard for it to shift rock held in place by soil.

[@frozenjoe6313]

That was difficult with the house and wall so so close. . In the old, old days the miners would build s fire to heat rock then quench it to break the rock. I wonder.... on any little jobs have you tried a some thermite to get it way hot, them water hose the rock??. It will make superheated steam which is very dangerous Please dont scald yourself, very dangerous>, but with lots of diirt cover and mats it might work well.and no explosions... maybe ...... Have you ever been drinking too much and tried that ?? Who knows, maybe the old ways will be new again ..........But I would stand way, way back under cover. ...

[@demolitiondavedrillandblast]

That is a very slow way to do it. A long time ago I have a very bad neighbor who had a nasty rock problem and I chose not to assist him. He worked for weeks using this method, he would build a big fire on the rock and then tip a wheel barrow of water on it. Pieces would fly of in all directions.
