It was an unfortunate incident for sure. Certainly a lot of wild theories for the cause at the time, I guess people were still learning since it happened over a hundred years ago. The B-C explosion is the same concept but wood dust, it's much more recent events, you would think they would have known by now. Also dust collecting rooms are not that effective at collecting it all. I'm sure it catches lots but not the fine floaty stuff.

Iron mines would make for a cool visit too, all the history eventually disappears and forgotten as infrastructure becomes unsafe with aging or new regulations. Visit them while you still can! The coal mine was cool to visit but it was booming at a time where there wasn't much for safety or living standards, many died from illness related to both like typhoid fever and such. I made a post about it a few years back, see if I can dig it up...I had to look deep!! haha but found it.
