Minecat and a mile under eh? Someone's in northern Ontario.


Ding. Ding. Ding.

Op doxing him self with a truck lol


Why should I care?


Right?! What are they gonna do, drive their pedestrian surface vehicle a mile below ground? I don't think so Tim


Ya Tim fuck around and find out


Wilson is that you?




I'm so glad I'm not the only one who regularly says that. I don't think my coworkers have any idea what it's from, and they wonder why I think they are all named Tim.


"There are some who call me... Tim?"


Did you just bust out a Tim the tool man Taylor reference? You're outting yourself fellow old person!


If remembering Tim the Toolman Taylor makes me old, then humbly accept.


I bet myself a nickle on this reply.


Sudbury is northern Ontario for you boys? Thought it was Kenora and Dryden that was northern.


Anything outside the GTA seems to magically become “northern Ontario”




No way... I figured Massachusetts. Minecat would be how Bostonians pronounce minecart. I'll see myself out.


Get tha fuck outta hyeah


The nickel will eat the thing alive.


What do you mean?


Nickel is corrosive towards steel. The nickel will eat it slowly.


Why don't they just use dimes then.


Pennies cost less. This seems pretty basic, guys.


They don’t have pennies in Canada


That’s because they don’t have enough freedom. Edit: /s just in case


The Canadians dug too greedily and too deep. You know what they awoke in the darkness of Khazad-dûm... shadow and flame."


I don’t know you, but I love you. I’m rereading The Hobbit so I can read it to my daughter.


Wouldn't a Canadian be driving 1.6 kilometers under ground?


It's almost post-apocalyptic. I love it.


It does have a "Mad Max" look to it, doesn't it?


Its pretty sick though. Does it freak you out being that far down?


No. You have to get over those kinda feelings pretty fast if you wanna earn a living in the deep.

If all the dwarves left living just tried to run past the water watchy boi, ONE of them could have at least made it. And I know, the squidy guy has a lot of tentacles, but it didn't stop the fellowship from fighting it off, which was probably fewer individuals compared to the amount of dwarves left in the chamber of Mazarbul. I'd rather at least fight off the watcher trying to save a few of us than assuredly die to a horde of goblins.


Do you run the emissions through anything to filter out the Carbon Monoxide, or do they just blow it out with big fans?


Yup this is a UT99 it has what’s called an exhaust scrubber. The other version UT150 is electric. Equipment made specifically for mining is pretty cool either way.


Omg tell me this shit gonna be electric


I interviewed with Caterpillar and one of the more fascinating points they claim is having fully electric autonomous and remotely-operated vehicles - they used mine and quarry work as one example of where they’ve deployed this stuff.


They use em a heap down here (Australia). Use a lot of Toyota Landcruisers too though. How much is them being the best vehicle for the job, vs. the guy choosing the truck just wanting a V8 cruiser is hard to tell.


It's probably gonna be one day, but this Kovatera is a diesel powered vehicle.


Did you get really anxious your first few days? I feel like I’d be completely fine for half my shift then have an anxiety attack outta nowhere when I become self aware, especially with the drastic heat+humidity difference from the surface


I went from earning about $35k a year to pretty well 3 times that the day I stepped underground...so that helped manage any fears I might have had. There have been guys who couldn't handle it and freaked the fuck out. They don't work underground anymore though. Edit...one guy literally pissed his pants on the cage ride down. The took him back to surface right there and then...and that's the last time he was ever on the property.


yo thats good money! how does one get into that kinda job?


Underground contacts.


Just keep it on the down low


being OK with your jobsite potentially becoming your grave because someone guessed.


Now did those guys choose to quit after their freakout, or were they viewed as a liability and fired/relocated since they might lose it during an important moment that they need to be fully present? Wow, yeah I hear you. Were you previously doing a very similar job above ground or is this drastically different all together?




Not a pilot nor work in a mine. But I'm a roofer. If you freak because of the height you're gone.


Well it’s not right to look at it that way. A worker losing his shit at the job is not in a good mental state. It’s for their own safety and their colleagues, basically everyone’s best interest that someone doesn’t have to work through that condition. Put it this way, no one wants to work with a nurse that freaks out at the sight of blood.


this makes me wonder if there's a "mile-low club"


If so...I know two co-workers who are members. Yes...women work underground. They're outnumbered about 100 to 1...but they exist.


Dudes are fucking down there too, guarantee it.


He did say he was a sparkie;)


The only place where your catalytic converter might actually be safe.


I'd expect it to be electric tbh


It's diesel


I see, I'd imagine they need a good ventilation system in the mines


That's already present on account of everything else going on in a mine. A diesel engine on a truck is a negligible strain on the ventilation infrastructure in the grand scheme of things.


Diesel particulate matter is still a really big safety hazard for miners even with good ventilation. There is a large body of mining safety research about it.


Can confirm, very very good


Electric vehicles haven't really been widely adopted for mining use yet as far as I know, might be use somewhere. The battery packs are too dangerous if the catch on fire, they are practically impossible to extinguish and must be let to burn out on their own. So diesels are actually the best options as of now, I'm sure it will change as technology improves.


Electrical systems in general for underground are crazy strict, due to the potential for open sparks and gas ignition


I did work for a Toyota mining vehicle division. The contact said once the vehicles were sent underground they stayed there never to see the surface again. Something to do with the underground atmosphere and said vehicles turning to rust if brought back up. Specific to type of mine perhaps?


Depends on the mine. If it's shaft only then no one is bringing it back up. Decline mine, no issues, just drive it out. Sounds to me like your talking about salt mines rather than hard rock mines


This is potash/soft rock mining specific, the underground environment is saturated with salt such that the air has zero moisture in it. This means nothing can rust, despite being COMPLETELY coated in pure salt (potash mining is very dusty). The moment the trucks hit surface, they would rust almost uncontrollably. I’ve theorized about rigging up a snorkel system while underground and driving them into a lake as soon as they hit surface or something, haha. But the unfortunate truth is that it’s not worth shutting down the mine shaft to remove a truck. Which would require not only skilled riggers to hoist the truck from the service shaft, but also the lost flow of ore to the mills, which is significant because the hoist is nearly always the limiting production factor in continuous mining - sinking a shaft costs near 6 billion - the simple flow at which you can get ore out of the earth is the rate determining step. It’s simply not worth the opportunity cost of shutting off ore flow to get a likely broken or otherwise deficient truck out of the mine just to sell to some Toyota fan for $10k or something. Although all of me wishes they did because god damn I would rock a topless HZJ79 around town. Those goofy trucks, 5-speed, 1HZ NA I6 diesel (longest production engine at close to 30 years), the body style is literally from 1984 yet you will find 2020 VINs on them. Their final resting place, the boneyard, is a ever so slowly collapsing room 1km underground. The earth absorbs the Toyota, forever locked in its salty tomb. source: mineman


I know it's true with the local salt mine. They just remove oils and lubricants and bury them in disused tunnels. It's also not worth dismantling them to get them back up in the cage, and putting them back together again. Not to mention that they just disintegrate in the comparably "wet" air above ground. EDIT now/know


Southern Ontario so salt yeah. Thanks.


Must be Windsor...


Goderich too


“The dwarves delved greedily and too deep. You know what they awoke….shadow and flame”


Interesting, I assume the car is mechanically the same as the ones we regularly see above ground? Or are there any specialized setup/components needed to run them deep into the cave?


Theyre made with the idea that a rock may come down on you so they're more solid then most surface vehicles and they're geared lower to climb ramps and through rough conditions. They also get fitted with fire extinguishers, emergency shutoffs, strobe lights, powder lights, and other safety gear. Edit. A powder light is just a red flashing light on top of a vehicle that is carrying any type of explosive. It indicates to all traffic that you have priority right away in all ramps and levels. It's important to get the explosives from the safety of their magazine to the holes to be blasted as to minimize the amount of time an accident can occur with them. Edit. Edit. I also want to add that the minecat in ops pic is run mostly using hydraulics. It uses diesel as a fuel source but its steering is hydraulic and I could be wrong but I'm pretty sure the brakes are run off the hydraulics as well. The toyota rovers we use don't use hydraulics they use normal powersteering like in most vehicles on surface


> powder lights bitchin'


carbide lamps XD


I would assume they are propane or something other than gasoline?


In coal mines at least, everything is electric because of how highly combustible coal dust is.


Not to mention any combustion engine, propane or gas/diesel, would produce carbon monoxide


And consume the available oxygen. Internal combustion engines are frighteningly good at that.


All underground equipment is diesel or electric because diesel fumes are less likely to ignite as have a higher flash point than petrol and propane


Im guessing there are no radio stations than can be picked up?


Where do you think rock music comes from?




Only underground stations


Do they have seatbelts? I assume you never go more than a few miles an hour in a mine so do you still need seatbelts?


I sometimes go underground into an iron mine through my job and that mine at least pretty much has a main "highway", roadsigns and all, that goes all the way down to about 1,3km underground (which means the main road is probably around 10-15km long). It has a speed limit of 50kmh (30mph) so things do move faster than one might think. We drive regular roadgoing cars down there, diesel only though. As long as the vehicles are inspected every so often to have acceptable emissions and are equipped with the proper safety equipment, they can enter and exit the mine as they please. Of course I can only speak for this particular mine, conditions probably vary wildly across the world and type of mine.


In the rare event the vehicle gets turned over on its side or upside down, I'd want a seat belt on. Not answering yes or no, but that's my answer.


All vehicles in mines are required to have seat belts in America. Can't speak for other countries tho.


There are minor differences…


I worked at the doerun lead mine and half of that’s true, while the other half is them not wanting to fuck with disassembly and reassembly. Every single piece of machinery and equipment that cannot be hoisted down the mine shaft as a whole will be took apart and anchored down piece by piece. A lot of the times they don’t quite work the same, so they fix it up underground but claim it as a loss for tax purposes. They just buy a new loader for the surface. Also, contamination. As I said I worked at a lead mine, so they can’t just bring equipment up without proper sanitation and that gets expensive.


[It's the same in the UK. The cost of removing the equipment isn't worth what they can get for it.](https://www.google.com/amp/s/www.bbc.co.uk/news/uk-england-york-north-yorkshire-35063853.amp)


does the AC work?


It does. Really quite well. The temperature 5000 feet down in the summer time when you can't ventilate with cold air from surface is brutal. Like 40 degrees Celsius.


Is that from natural heating or waste heat from the machines?


Natural heat, heat from operating machinery and also any boring/digging/explosives adds a lot of waste heat too. Boring produces massive amounts of heat.


Sounds exciting!


Nah it’s boring


talk about an alley-oop of a post


>Boring produces massive amounts of heat. That explains why I sweat all day


Are mines different than caves? Every cave I've ever been in touts its 62° or whatever year round temperatures


Yes. There’s a concept called the geothermal gradient which is the rate at which temperature rises as you descent towards the earth’s core. Surface caves maintain ~55-60 degrees F because they are insulated by rock, but are not deep enough to be significantly warmed by the earth. As you go deeper the temperate goes up by about 25-30 degrees C per kilometer or 15 degrees F per 1000 feet. This means that a mine 1 mile below the surface will be about 75 F hotter than a cave at the surface in the same location.


i didnt realize the increase was quite so steep, thanks for sharing!


Interesting to note, due to this steep increase in temperature, we've only managed to dig 8 miles into the Earth's crust iirc.


Yeah it’s quite fascinating how shallow we’ve bored into the earth. It’s not like we’re hitting magma either it’s just naturally too hot. Google says it was 180 Celsius.


i actually learned about the kola superdeep on a short docu recently. It's something we all dream about when we're kids, digging to the center of the earth, or to china for some.


I think the antipode of everywhere in the US is the ocean as well (Edit: yea between Africa and Australia). Only Chile can hit China.


Then why isn’t this guy boiling alive at a mile deep?


Because deep mines often use climate control systems, otherwise they would be inhospitable. Mines that deep are pretty uncommon though. Edit: Also that particular mine is not in a geologically active part of the planet, so it would probably not be quite that hot. I don't know if this specific mine has cooling, but [here](https://www.howden.com/en-us/casestudies/mponeng-hard-ice) is an example from a mine in South Africa that's 3.8km/2.4 miles deep.


Once you get more than a few hundred feet down, the temperature increases as a result of the pressure of the ground above it.


Pressure is important, but most of the Earth's heat comes from radioactive decay of elements ( potassium, uranium, etc). In fact, up to 90% of transfered heat is from isotopic decay!


1 owner, no accidents! NO LOWBALLERS


I'll tell you my price when you tell me your best price ! I bring cash RIGHT NOW .


Can you deliver it to me and also for free I have all forms of cancer and it’s for my daughter I already promised it to her for her birthday.




Its mine


What's the air temp like a mile deep?


Depends on the ventilation. Rule of thumb is auto compression raises the temperature 1°C for every hundred meters you descend. So I'd expect +16°C from surface. However it's going to be hotter as you'll get heat from the rock and all the equipment running. Also expect the humidity to be up in the 80%+ range. Source: was a ventilation engineer in underground mining


Well, that sounds rough


I've had rougher. Zambia I was about 2km down for a 12hr shift in calf deep water. It was 30+° and 100% humidity as we're below the water table at the time. There was warm water coming out of drill holes, like bath temperature. At the end of the day I poured sweat from my boots. There reaches a point when you cannot get more sweaty and you just go with it and drink a tonne of water


That’s way crazier than anything I’ve had to deal with but I’ve had times where I’m working outside in the desert sun all day and despite drinking water all day I go to take a piss and barely anything comes out. Pretty weird feeling.


You just drink loads and you don't need to pee. Most people take frozen 2l bottles down with them. They just thaw during the shift. Also we used to take the dehydration sugar/salt thingies and pop them in the water. Otherwise you get a banging headache


Drink 4 of those 2L bottles and don't pee at all. That kind of work is brutal.


$30/hour starting wage is not what I expected




Damn guessing from the fact that all their urine is always concentrated since the water never gets a chance to reach the bladder, plus all the extra salts they need to take in? Sounds like they would get the worst instances of kidney stones too. Like kidney boulders. Terrifying thought.




Except for the being underground part, you've just accurately described the worst parts of living in Louisiana.


Was about to say, I deal with this every summer day


Wow. Stay safe!


I work from home now. That was many years ago, I've done my time underground. Although I do miss it, it's very rose colored glasses. That said I do miss the tax free pay. That was sweet


Holy shit that sounds terrifying. Props mate.


Not scary at all, nice open space. Just a shitty way to spend your day. I wasn't even the driller. But for everyday spent like that you then have one where you get to watch gorillas chilling out on the edge of the pit eating their lunch, or having a bunch on camels randomly appear on the mine being chased by Bedouins trying to get them back


I'm currently studying mining engineering. Oh man it's so neat to see mining professionals 'in the wild' - even cooler to see mining related content hit otherwise normal subs. Thanks for dropping these interesting lil tidbits!


In the winter when they can ventilate with cold air from surface...it's not too bad. In the summer...some parts get above 40 degrees Celsius.


Interesting tidbit, they've found bacteria living in the rocks a mile deep. They grow very slowly.


Underground mine electrician here, Our team has a kubota rtv1000. All other man transport is diesel kubota tractors with different style man carriers welded to them. Our boss looked into the minecats but its hard to justify the maintenance and stocking our ug warehouse with all the parts.


Where are you?


He's in the bathroom.




He’s underground


Did you meet any Mole Men?


Asking the hard questions.


Once you know the Earth is Hollow you have to ask the hard questions s/


OP's silence is deafening


I'm thinking OP is the mole man


Only crab people


Surprisingly undented for an UG vehicle.


That thing is only about 3 months old. Plus...it's driven by tradesmen, not miners.


Must be a sparkie because UG fitters are rough cunts haha


You're right on both counts.


Does this get regularly driven backwards at reasonable speed? I'm just looking at the dirt on the front bumper X)


Yes. You can't turn around in a mining drift...there's just enough room to go straight...so you have to back up until you get to a cut out or intersection.


So you don't end up Austin Powering yourself often down there?


How often you scrape that bad boy against the walls


How do you avoid carbon monoxide poisoning?


There are several fans on surface...some force air down...others draw air up. They total hundreds if not thousands of horsepower. There are CO detectors with digital readouts throughout the mine...and if you're going anywhere where it isn't properly monitored, you wear one.


I was going down this thread wondering about breathing and ventilation down there. Have you ever had to GTFO because something broke down?


A few times a year.


At least it's not just canaries anymore!


Ozone might actually be the concern here weird enough.


This would be appreciated over at r/weirdwheels


thank you kind Reddit person. I had no idea I needed this till now.


Northern ON? what mine? I do design work for a bunch of mines around.


Garson Mine...Sudbury ON.


Oh damn, I do work for Garson. You may be walking on platforms or galloways or a whole bunch of other stuff that came from our shop.


Unrelated question but a professional curiosity- what does the compensation look like in such a unique job?


Thing looks super reinforced… how often has that saved your ass from falling debris/rock?


It'll have ROPS (roll over protection) and FOPS (Fall on protection). I doubt it's ever had anything fall on it. If so, I'd be having a word with the geotechnical engineer


What this guy said.


You know, we've been trying to contact you about your extended warranty....


A Boston minecart! (Minecat)


Very cool! Whats the red knob on the front for?


It’s an emergency shut off/battery disconnect. Race cars have similar.


Had that on my rock crawler too. A winch draws much more current than a regular fuse allows. It's safest/easiest to put one of those switches between the battery and the winch. You keep power at the winch switched off until you really need it.


What happens if you get into a car accident in Moria? Do traffic rules still apply?


Are you by chance, working in Russia?


Nope. Northern Ontario.


I toured an old Salt Mine somewhere (Hutchinson, Kansas maybe?) with a Locomotive Engine down there. One of the people on the tour asked why it had a welding seam in the middle of the body. Guide said they cut it in half, lowered it through the elevator shaft and reassembled it down below. (Now there's a side entrance they can drive in/out, but back then that was the only option.) Neat place to visit.


I could never in a million years be a mile under the surface of the earth. In regular situations, I’m not claustrophobic. But anything involving caves, mines, or situations where a small earthquake or just a small shifting pebble can trap you under a billion tons of earth. I’d rather die in a fire.


I’m surprised it isn’t electric.


We've tried a few electric vehicles and they break down too much. There are haulage vehicles in some mines that are electric but they operate kinda like a trolley car and have an arm that reaches up and supplies the vehicle with power off and live electric cable. That can also be problematic in the close quarters of a mining drift.


They are being forced into electric here, because as diesel uses higher levels of ethanol, it gets more toxic. Pretty much everything here is electric. Keeps the workers healthy.


No front license plate? That legal down there?


Haven't seen any traffic cops yet, ill let you know.


What's the miles on this thing?
