TTerrible posted:I really did not enjoy him packing the void with black powder and then placing it on top of another anvil. Wiggling it. While bending directly over it. Surely he has to be grinding some black powder residue between the two anvils when he does that? You can mill black powder in a ball mill - it takes an ignition source to set it off, and "merely" grinding it between steel surfaces should not do it. Not that I'd be comfortable with it, either.

LifeSunDeath posted:watching some trainhopping vids and the guy's usual insanely dangerous climbing on roofs is outshined by sitting right over the wheels of this train: Ha, I have thought about posting Shiey in here before, but concluded that since he seems to know exactly what he is doing, and that thing is deliberately outside the rules, it's sort of borderline. The train wheel thing is a different kind of risk than his usual "climbing up a bridge tower in sandals", though - and more in the thread spirit.  Also, I never connected that "until" is just Norwegian "inntil" with some vowel drift. ("Inntil" has remained "close to" in Norwegian - while plain "til" means, among other things, "until".)

Oh, but management was worried about theft during the cooling period so one middle manager went to harbor freight and bought a padlock and chain for the doors with just one key that he keeps in his pocket, and he had left early to catch a showing of Herbie Goes Bananas. Add in how the night janitor had stored a crate of paint leftovers and insecticides in a booth that had been unused for half a year and produced toxic smoke when heated, and ... I may have read too many accident reports.

Mine tailings are presumably just the rock you dug out minus one of the component minerals. Is it fine to stuff it back into unproductive mineshafts, or does the increased drainage from the tunnels and the fracturing of the rock make that problematic? As for the superfund apartments, I wonder - if they did the cleanup job properly, the new apartments could plausibly be better than the properties downwind outside the cleanup area, and you may get good deal just because it scares off some buyers. On the other hand, that's a big if.

Jabor posted:Often times the tailings also include traces of nasty stuff used in the process of extracting the desired product - for example gold mine tailings having a bunch of mercury and cyanide. Right, that's kind of important. I was wondering more about the minerals where you can do mechanical separation (first), so you have "clean" tailings - those can still leech all sorts of things you don't want in your water, but on the other hand they're literally just rocks out of the ground. It's kind of a stupid question, but I was honestly just wondering if putting them back in the ground would be good enough, or if the increased water permeability makes that a bad enough idea that it may be better to keep them in a pile you can monitor.

stratdax posted:This post is pissing me off. "Presumably". All you have to do is one google search. You think mines just.. take one element out of the rock, and all they're left with is just rock? And no byproducts? What the hell. Depending entirely on the mine type, the first stage of ore refining can be fairly simple. There is an old molybdenum mine up near our cabin that closed in the 70s, for instance. The first step there was floatation: grind the ore to sand, churn it in water. Molybdenum sulfide will apparently stick to the bubbles and end up in the froth, while most of the uninteresting minerals stay in the water; a few stages of this will get you much purer ore. Reading about it, you can apparently get better separation from other sulfides in a basic environment, so you can add lime; some modern frothers use xanthan gum based foams. Neither seems to have been in use at this specific mine, but it's not clear. Anyway. This means your first, and by far largest, waste stream is effectively "everything that was in your ore, minus the few % of molybdenum sulfide". (Possibly with lime and/or organic thickeners). Which is why said mine has a huge sand bank outside now, slowly releasing whatever else was in the ore into a river. Other minerals have other processes - "use an overgrown tomato sorter to kick rocks that look wrong in X-ray to the waste belt" is apparently common enough that I've seen ads for the sorter machines on youtube. This, again, means you get a waste stream of rubble that doesn't contain enough of your ore - but could still leech who knows what. Which brings me back, again, to: would it, as a general idea, be ok to stuff that sort of material back into the mine shafts, or is that just asking for so much trouble it's actually preferable to keep it where you can easily keep an eye on it? E: obviously, processes that add chemicals change the problem - but there are enough types of tailings that are literally "what's left" and still problematic.

Memento posted:Yeah once you've removed the overburden on a coal mine (everything on top of it that's not coal) the coal deposit itself is effectively 100% coal. Which is also interesting - I don't think modern plant matter has the same concentration of heavy metals and other fun? Is this a case of the already-transformed coal filtering it out from ground water, or were the relevant plants more "apex predator" style pollutant concentrators? Something else? ... you don't have to answer that, I can read about coal (and the heavy metal content of modern biomass) on my own.

The Lone Badger posted:In Australia it's OH&S (Occupation Health & Safety). Arbeidstilsynet here - literally the work-to-lookers, though I guess something like Workplace Monitor or Employment Watchdog would be more idiomatic. They also handle general employment law, so "this will cut someone's head off" and "this contract demands illegal working hours" are two working groups within the same organisation. I'm not sure if that makes any practical difference. There is also DSB - Direktoratet for Samfunnssikkerhet og Beredskap (the directorate of societal safety and preparedness), who write the rules on transporting and working with the different hazard diamond materials, electrical systems, emergency services, and generally all aspects of "try to keep the country from burning down or blowing up". As I understand it, this means it's on Arbeidstilsynet to point out that your workplace doesn't follow applicable rules, while the DSB writes the rules for some of the specific hazards- and can do their own inspections, sort of like the ATF. e: Norway.

Ha, yeah. I can't help but think it looks worryingly top-heavy for towing like that, even when I logically know how most of the structure is under water. Having that many towboats surrounding it in such a wide fan seems like a sensible precaution.

In this case, it's refreshingly simple: hydrocarbons are made of hydrogen and carbon (only). They are the major components of oil and natural gas. As an example, methane is the simplest possible hydrocarbon: one carbon, four hydrogen around it. HF, hydrogen fluoride, is even smaller: one hydrogen bonded (loosely) to one fluor.

In one way that's understandable: having pilots that are comfortable doing all sorts of non-regulation, difficult maneuvers could be useful in certain situations. More so in an air force than civilian flying, at least.

My primary school had a house rule that catching a ball in your hat was of equal value to catching it onehanded before it hit the ground - which is to say, better than a twohanded catch. Don't ask me to try and map Norwegian playground ball games to US equivalent, but it was vaguely in the baseball family.

Azathoth posted:is the player like double put and has to sit out the rest of recess or something? IIRC - and it's been literally thirty years - there were two ways to get to an infield/outfield swap: either the normal way of running out of possible batters, or by the outfield getting enough fancy no-bounce catching points. I think the outfield needed to hit a running player by throwing the ball at them to stop them, but a fancy catch ... probably also counted? As I said, it's been a while.

On one hand, true. On the other hand, a slow electricity leak into my basement doesn't turn my house into a bomb, and accidentally digging into electrical mains does not carry an overhanging risk of levelling the entire city block. (Also, brushing your hand over 230V may be both risky and unpleasant, but I've done it enough times to confirm that it won't instagib you either.)

That's fair. Punching through something like a long distance HVDC cable would be better experienced as a youtube documentary a year or two after the crater calms down. I'm just saying that if we had never had piped gas outside industrial settings before, we would have looked at it with some distrust if it were suggested today.
