I am a mining engineer. Still not sure how I got into it, but I did. And so far in my career I've enjoyed it. As for whether or not it's suitable for aspies, I think that depends very much on the particular aspie's abilities. It is a pretty harsh environment. You're constantly around loud, heavy equipment, it's often wet and either really hot or cold depending on the conditions at your particular mine site, you will almost certainly be working long hours and during all hours of the day (especially if you are at a fly-in/fly-out operation), and there are numerous potential safety hazards and being able to communicate these hazards to others and safely navigate around them yourself is essential. That being said, it's an exciting career, you will never have a dull moment, the people are usually pretty fun to work with (though miner's can be quite crude at times), and I personally really enjoy being two miles underground. I primarily work in an office environment, though I have also spent a summer out in the field (doing surveying work mainly) and will soon be spending a lot more time in the field. I can tell you that it is definitely a struggle for me sometimes, but I enjoy it so I'm still doing it. I also know that I personally am a rubbish equipment operator. Partially due to autism related issues (getting overloaded by my environment and visual-spatial issues) and partially just because my eyesight is not that great, though not bad enough to actually warrant any kind of restrictions on my license.
The skills that you would need to develop are communication skills, the ability to operate heavy equipment (not much you can do there without being trained on site... however, not knowing anything about your particular abilities, driving is a good place to start), being aware of your surroundings, and physical strength. Most mining work now is pretty much just sitting in the cab of a piece of equipment and operating that equipment... which is not unlike playing video games with many modern machines, but there can still be a lot of manual labor involved.
Again, the roles that you would be best suited for would depend very much on your abilities. I can tell you that most equipment operators start by driving haul trucks and work their way up from there. There are also jobs running plants for processing the ore later in the process, or other miscellaneous jobs like security, janitorial, or being a mechanic. There are also various "office" jobs such as geologist, surveying, engineering, safety professional, and managerial positions (you will still spend a fair amount of time actually out in the mine). Typically you won't get an office jobs unless you've had some kind of schooling, however. I have seen exceptions to this, though. I once met a guy who went from driving a truck to doing all of the surveying work for a mine site.
As far as pay, I'm not sure exactly what most miners get paid, though it is typically worthwhile. Also, I don't know too much about fly-in/fly-out operations, but based on stories from some of my friends, if you are at a man-camp they are probably going to make it worth your while. Also, I'm not quite sure about the situation in other countries, but in the U.S. at least the mining industry is starting to wane a little bit. It's very much a boom-and-bust industry, so it'll be going great and be really growing for a couple of years and then the price of whatever commodity the operation is mining will drop and suddenly things really slow down, which doesn't make it any less worth it if it's something you want to do, but it is a risk to be aware of.
