What is happening? Say they are remote controlled.

That's a quarry during blasting. The holes are being drilled and filled with explosives according to blasting engineers project. The explosives used are usually ammonium nitrate and oil emulsion or regular anfo. They are delivered by trucks called "memu" The trucks actually create explosives on site from half products. Those explosives dont usually trigger easily so a stick of dynamite is used for each hole to trigger an explosion. Dust supression is probbably due to people living next to quarry complaining about it. On dry days the roads on quarry are sprinkled as well to mitigate dust getting airborne from heavy machinery driving around. Products created are rock aggregate used for building roads, train tracks, fundaments for buildings,etc. Im not sure if those trucks are remote controlled because laws regarding that are different from country to country, but they may as well not be if the cabin is well protected from flying debris.

I really appreciate that you took the time to make this comment, thanks


rocko430

Dust suppression is epa mandated.


stcbythesea

Oh my word, thank you for explaining this. I thought the spray was causing the dirt to cave!


Healter-Skelter

LOL

There can't really be a salary that negates the fact that people sit right next to explosions?


m6_is_me

Explosives are a fairly understood science at this point. People get paid huge amounts to know the correct charge sizes, the safety procedures, etc etc. They're buried in sand/dust/rock, so not a high chance of you being caught in the blast radius. The most dangerous thing would be the ground beneath them sliding out as well, but even then they're inside protective chassis.


Avarus_Lux

if there's one thing we humans have quite a good grasp on it's explosives, destructive forces and how and where to apply them haha


Gargulec88

It is a solid rock. Explosion is directed toward a face of the wall, or if someone fucks up and doesnt fill upper part of the hole with aggregate it would shoot up like from a rifle. The most dangerous area would be in front of the wall. There can be high velocity debris flying in direction in front of face. It is a very responsible job for an engineer and blasters to use enough material to crush rock to proper size and not enough to fuck someone elses car few hudred metres away with a rock. From the person in a car behind the site, it feels like a fart in a pillow. Its not even really loud. Only ground shaking a little bit. Still a protecting solid metal cages are used for people who need to detonate.

It depends what you’re blasting. The native rock where I am is hard af and have to be loaded accordingly for proper fragmentation which makes a lot of fly rock. Our clearing policy for blasting reflects this by requiring a minimum of 1500’ from the patter(s) being blasted. (We do 1-4 patters a day ranging from 100-800 holes a day.) I can also tell you for a fact this is not the United States, and if it is, the company is fucked. There is no corral or safety berm mandated by MSHA.

People that do hard, dangerous work are rarely well compensated. And this work isn't particularly dangerous.


nogooduser

The one on the left of the picture was pointing in the wrong direction and the other one had to spray over their head to cover what they'd missed.


flasterblaster

Guy on the left doing the absolute minimum. "Boss said to park here and spray over the edge, that's it." So he did exactly that then checked out till the job was done.


Elmst333

Right spray looking like left shark out there.


gogetter510

They touched streams.


bobcrotch

Where the hell is the reservoir? I realize it’s far away so maybe they have internal tanks?


Healter-Skelter

They have unlimited ammo


bobcrotch

Must be running the p2w booster

I’ve lived less than a mile as the crow flies from a quarry for 30 years. They usually blast between 10:30 and noon on weekdays only. I feel a slight rumble a little stronger than a loaded semi truck driving by at speed. Not enough to wake me but noticeable. Quarries usually have ponds and a drainage system so plenty of water is available.


mycroft16

I can see Bingham Canyon Copper Mine from my house. Place is stupid enormous. Not sure if they have resumed inside the mine visiting since the landslide a few years ago but you used to be able to go in and watch from high up all of the operations including blasting. 3mi wide and 0.75 mi deep. They can be blasting in multiple locations while actively shoveling in others. Utterly mind boggling the scale of the thing. Explosives are definitely something we are good at as a species.

1. Silicosis exists. 1. Water is infinitely recyclable. 1. Air filters are not reusable. 1. Water quality is a spectrum. Some water is suitable for industrial use, but not drinking. 1. In many parts of the world water is abundant and droughts are not an issue. Pick one.


ClockworkTalk

Ruthless 😂


raverbashing

> Pick one All of them


BurzerKing

So that people don’t get silicosis

Because your house is made out of rocks ground into a paste and cemented on the spot, and somehow you agreed modern comfort is to live in a house made out of ground rocks. Plus rocks contain everything that is tech, integrated circuits, magnetics, precursors for awesome materials, literally everything has ore mining as a first step in manufacturing. Or any of /u/toolgifs arguments. Or all of them.

> Why are we wasting our water to get rocks? Because rocks hold minerals and elements that we need to make things. Copper, gold, silver, aluminum, lithium, molybdenum, ect come from extraction out of rocks, clay, and limestone. > This sucks as a ultimate. Operations don’t use good water for this type of thing. It is non potable water that is reused for these things. For example the operation I worked at for 15 years, had onsite reservoirs that would collect all sorts of sources of water. Ground water/aquifers that was being pumped out to prevent flooding, rainfall, use like this what will either evaporate and return to the cycle, or would end back into the pumps to fill the reservoirs, etc. It is a necessary evil. We have to mine to sustain ourselves and to reduce the impact to the environment and communities there are practices in place like dust control. That said agencies (EPA in the United States) require opacity readings to monitor the dust in the air. Opacity is too high that means there is too much dust which means citations are written.


phine-phurniture

MSHA and OSHA should be barred from seeing this gif.... are those trucks manned?


not-a-croc

What a waste of probably fresh water
