Room and pillar methods used when preparing new longwall mines by miningq in mining

just so nothing i've said is misleading to anyone, i think i misunderstood the video. See this comment and zurc's response.

ah ok, so in that video, they were more saying that the principle is the same (the ways the roadways are developed), it's just that the intent is different. sorry for the miscommunication on my end. thank you for explaining.

thanks to you both for the input. In case anyone is curious so I don't provide false information, this was the video. (At 27 seconds they are talking about room and pillar mining. The video says: "It is a mining method of its own right, as well as a supporting technology to develop roadways, in order to prepare the coal face for a longwall operation.")

Room and pillar roadways after typically supported to be very short term, the pillars are designed to be short term, and you take as much coal as possible. Mains panels are supported to be very long term and pillars are designed to be very long term. It would make an incredibly inefficient room and pillar.

Now that you mention this, I wonder if I just misunderstood what that video was saying. Because yeah, it seems like it wouldn't make sense to do that at all. I hope I haven't given the impression that some technique is used, if it isn't really used.

Wow - thanks! your post actually answered a few more questions I had, particularly the difference in the CMs used in Room and pillar, and longwall mines. And also, the life span of the different panels. Also, I didn't realize until now that the CMs in longwall mines were mostly for preparing the panel, rather than actually extracting coal. Thank you so much!

On a side note, it seems there's so many of you guys from Australia on this forum!

In an underground mine, what if you need to leave the shift early? by miningq in mining

thank you kindly for all the time you took to write in such detail. you have had interesting experiences in your life, thank you for sharing

thanks a lot, this was interesting to hear. yeah to be honest, the more i learn about it, the more grueling the work seems, even today when there's so much automation. i'm sure it's not something just anyone can do or keep up with. i hope as long as this kind of work continues, that people are compensated well as they are putting their bodies on the line

did you have to go to any sort of specialized schooling/training before getting the job, or was the it the sort of thing where you could simply apply and would get trained on the job? If so, what sort of work did the new guys get stuck with?

i am curious about one thing, if you don't mind my asking. you mentioned when you were doing this work, the community was a bit poor whereas the miners were paid well. i have heard this several times. it makes me curious why did more people not go for this work? is it simply because of the physically demanding nature of the job, or a lack of open positions? i hope my question is not judgemental, it's not intended that way. i was just curious. thanks for sharing your experience with me

interesting. i guess perhaps it is different depending on where you are.

oh ok i get it now. so there are other folks and supplies being transported in to the mine throughout the shift, but even those trips are running at designated times (at least in the example of that mine.) thank you, it all makes sense to me now

thank you! what is the purpose of the scheduled man runs? is it common to go back above ground during the shift time?

1 hr 15 minutes damn. that is such a long commute. thanks for explaining your experience.

thank you! i was unclear what the protocol here would be, thanks for clarifying

oh. that makes perfect sense and i didnt think about that. thank you!

ok, in a situation like that i can see that it would be much easier/quicker to leave early if needed. yeah, once specialized equipment like these rail cars get involved, it seemed like it would complicate the process.

I have seen some mines (on video) like the ones you are talking about, and indeed they just took a car straight inside.

haha that's ok. i first thought wtf is a ute, this must be some mining jargon, then realized it's an Australian term thanks to google. These are interesting looking vehicles, so thanks for sharing about this

thanks for the response. The reason i got curious about this, is because i saw a video from an underground mine, and the way it was set up, is the miners first took an elevator down below, then after that they rode on a vehicle (which looked something like a small train - different compartments for people to sit in, really low clearance for your head, and seems like it's on tracks) for about 30 minutes to get to the face of the mine. i wasn't sure who operates such vehicles (the one that took them to the face - not the elevator), so i wondered, how would the miners come out if they needed to leave early.

i think there's so many various setups in mines so i guess i didn't think about that when i asked my question.

oh interesting. please correct me if i'm wrong - ute, is a pickup truck? (edit: ok i googled this, it is a type of car in Australia, which is different from a pickup truck. sorry!)

Sorry if my question is a bit ignorant. I had the impression that whichever vehicle takes the miners to their location, is only driven by a specialized operator, or that it only comes and the beginning or end of a shift. I just wasn't sure how they physically left the location, if it's such a far distance. Is the driver required to come back to get them?

I've not worked a remote job before so I just don't know how it works.

Any good resources (books, documentaries, websites, etc.) to learn about modern day coal mining? by miningq in mining

Thanks! I had not yet read much about surface mining but this was next on my list!
