Blasting a power trench through Granite

This week we helped get a trench through a massive piece of Granite for a large power cable on a huge remote farm property. No need to cover the shot out here, just get well out of the way! Anybody that has ever done a bit of blasting will well know that not every blast goes right first time and the rock does not always do what you want it to, despite strong encouragement! We got it all out in the end though.
I know that there will be several comments along the line of " you have a bit machine with a breaker, why did you not just use that, why did you waste time blasting it bla bla?" Listen up, this digger is a Hyundai R 320 LC 9, weighing in at 32 Tonnes (big and strong), have a second look at the point on the breaker. It looks like an old lipstick, it was new and sharp only a few hours ago! We have lots of rock here that kills big breakers. The only reason that it was effective after the blast was because the rock was full of stress cracks.

[@ChrisB257]

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.

[@demolitiondavedrillandblast]

That was a shrapnel hit!

[@olduhfguy]

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 !

[@demolitiondavedrillandblast]

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.

[@frozenjoe6313]

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................

[@Kaptain13Gonzo]

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.

[@demolitiondavedrillandblast]

Agree, the horizontal flaw was the cause of the failure. Thanks for watching Kirk.

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.

[@demolitiondavedrillandblast]

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.

Thanks for subscribing Peter, that really helps a lot, if a high number of people subscribe the YT algorithm will promote the video harder and thus make more add revenue... I have always promised to plow most of the money back into making better videos, I'm hoping to be able to buy a Kronos 2.1 super slowmo camera soon, it does 1080P @ 1000 frames a second, where as the current slomo is 240 frames per second and it compresses up the video a lot when there is a lot of motion. Cheers from the Land Down Under.
