Topic: Mining underground? (Read 282 times)
I just came back from seeing a mining farm that was done underground. Since the area was primarily granite base the enclosed area need a certain amount of airflow to get rid of the Radon gas but otherwise the area was pretty inert and was able to accept 20KW of heat soak without problem. I assume if nobody will be living in the area the Radon gas won't be much of an issue.
I recall back then an immersion cooling...it was revolution by Fluorinert by 3M https://www.3m.com/3M/en_US/data-center-us/applications/immersion-cooling/. Of course this solution is not for puny mortals but for mega-datacenters with special HW that is submerged in liquid.
Bitfury has been doing that for ages. It remains as the most effective way to cool the miners and eliminates the problem of miners being excellent dust collectors. Even in a data center with fairly clean filtered air coming in, because of the very high airflow through a miner the heatsinks/fans in them get very dirty very fast. Then there is the issue of hundreds/thousands of fans that WILL fail sooner or later.
With the 2-phase cooling from immersion in Flourinert, only the outside 'dry cooler' heat exchangers gets dirty and they pretty much don't care. Use magnetic-coupled sealless pumps to push the fluid around and you have a pretty much maintenance-free setup.
don't forget building underground costs more than above the ground not to mention proper ventilation due mold and water condensation...at least that is what I have heard while helping on construction sites.
Czech hosting company WEDOS "soaks" their datacenter in oil and uses that hot oil for building heating.

I wonder if someone ever tried to build a water tank where is a box inside for a computer and walls thermal exchange works as combustion engine. After all, water is perfect coolant and with little bit Glycol (used in VAG cars for example, marketed as G12-13).

I have to build a concrete base for a summer house in my garden. I had a bit of an idea that I might dig down and actually build a concrete bunker underneath while I was at it, in order to house some miners. Just wanted to find out whether anyone has actually done this themselves, and what solutions they had for heat, air, soundproofing? Electricity and internet connection should be easy enough.
Or is it an unfeasible idea?

My 'main' mining setup is underground, and it's air-cooled. It works very well, currently around 2.6PH so there's a lot of heat too.

If you're talking $ you probably know already that price of electricity is your worst enemy, and I see you're from the UK (??) auch
As for the rest, soundproofing shouldn't be an issue if you plan on building a bunker, minimal insulation between the concrete pad and the floor with rock wool will deal with it. The problem would be the airflow, pushing hot air outside from underground is simple, pumping fresh air might get tricky depends on the scale you have in mind. There are a few members who have insulated their garage, a room, a basement but I don't remember somebody putting them inside a bunker.
You might get a few hints from Steamtyme's topic.
You're probably going to have to work out a way to water cool the miners while they're underground (through running water) and it probably depends on the area you're in how well this will work out.
For anywhere in line with northern Europe you could probably concrete out an area above ground as a lake and use that to cool the miners (if you get enough rainfall) otherwise you'll probably have to attach it to the mains. Also if temperatures fall below about negative 10 degrees Celsius briefly or 0 for a long time there may be an issue keeping the water as water (so you might need a mains backup anyway).
Depending on how far down the miners are, a large concrete block might do fine at the entrance for stopping the sound from coming through, the vibrations might seem a bit weird though if they can be felt first...
