Rock drilling and blasting works for the the building and construction industry, for earth movers and anybody else that needs the ultimate power tool. The aim of this channel is to promote the safe use of explosives as an early choice option for solving difficult excavation problems. - We are always breaking new ground!
Last July 4th I did a fireball consisting of a gallon of methanol with some boric acid added. It makes a nice pale green fireball, but you have to wait for full dark to get the best effect.
@@demolitiondavedrillandblast thanks for the response I appreciate it . Was curious how it looked after as I was considering a project like this. Thank you.
Plenty of uncovered big bangs on this channel if you did deep, here is just a few - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0oyX5MUh1bg.htmlsi=9dVlj9zEf_uH6jjH
Why don't the developers build on top of the rock and backfill the services? imagine the savings of laying out at ground level instead of in trenches (cut and paste development needs 3D computer-screen-flat greenfield, I think).
MM77 Approved 👍🏼 👍🏼………………………………………………………. I’ve told you before that I believe Australia is a big rock with 6 to 24 inches of dirt on it and you said it wasn’t. I don’t know, you seem to stay pretty busy! If it wasn’t for the LONG plane ride and all the animals and insects you have over there that can kill a man quick, I would come over there to see for myself!! LOL😂 I hope they don’t run out of rocks so you won’t work yourself out of a job! Good work and great videos, keep it up!
23:25 What happens if you leave the water IN?? My only guess is it may reduce the effect of the explosive? Edit: !! I just noticed there's no explosive loaded yet! .. So the water would definitely be in the way ... I assumed it leaked in after setting up the shots.
Water in blast holes is a nuisance, particularly when you want to use a granular explosive that is very hydroscopic and quickly ruined by water. This is whey the explosive is loaded into a plastic sleeve, second issue is that granular stuff in the sleeve floats, so the water has to go.
7:50 I was building a house (years ago) and we needed to lift up about 3 feet of layered limestone at the deep end, and a foot at the other end of the basement excavation, (plus s good deal of dirt) I had an acquaintance with a regular backhoe, booked to do the job, but he got busy, and asked if it was OK if he send his brother over with a full size excavator (even though it'd be over twice the hourly rate) I did not hesitate "Yep send him over" We didn't even need to use the jack hammer, he got under the limestone and peeled it up! .. did the whole job in one day!! As long as you can FIT a bigger digger INTO the job it's almost always way better!! :)
Depends on the rock, the 49 Tonne excavator that was on this job had a huge hydraulic breaker attachment, this was quite useful for breaking the post blast oversize chunks, but useless trying to break out the big stuff in the ground.
@@demolitiondavedrillandblast hahaha, is the spade work because the digger could in theory exert enough force for the charge to go off? Or is it just to be completely on the safe side?
Good question 739, it can if you don't do it right. Back in the old days this would very often happen and you would have unfired charges being dug up everywhere.
There is a lot of ways to define spicy. I have heard of spicy being a 1 ton boulder being thrown 1/2 mile through a house wall, into a bath tub. That was a spicy meataball. It has happened more then you would think. As long as reasonable precautions are taken, and you have a reputation for safety, the states and feds can go either way on license status.
Im sick of wind n rain.... well it was clear today but dads place got flooded again. Hes too old for thos crap. Council are meeting me there Wednesday. Maybe i borrow some 'send it' stuff to remove the obstacle blocking the water....
Both Keith, there is no way I could get away with the noise of an uncovered shot on this site, could probably get away with the fly but they would not want it spread all over the place and the nearest neighbor is only 60m (200ft.) away, just take a complaint that one spec of stone went over the fence and I would be facing the regulatory authorities in court. So we cover it.
@@demolitiondavedrillandblast 60 meters it didn't look tight you must have not gotten that angle on camera long enough to judge it! from my estimates you had at least a 100 meters in each direction on all the shots.
