Of the three footnotes in this piece only one works and that leads one to a lobby group (the Illinois Coal Association)--not the picture of nonpartisan information. There are "further reading" links to a book review that focuses on coal in Appalachia and stops at 1945 as well as an "educational" link to an Australian University that educates students on how to extract coal. Again, this presents a single side to this extremely controversial subject. Claiming immediate subsidence a benefit is as well an interesting take on this violently disruptive effect. This is not a neutral entry. This is not a quality entry. —Preceding unsigned comment added by SADouglas ( talk • contribs)
I'm having trouble following the "
Modern methods" section. It jumps immediately into discussing "gate roads", without ever defining the term, nor linking to another article which does. As someone with absolutely no familiarity with mining jargon, this doesn't mean anything to me.

Like all potentially contentious articles in WP, the refs are weak, to say the least. Newspaper articles, blog websites, etc., are not good refs at all. Such things are symptomatic of politically motivated idiots grasping at straws. (Anyway, most contributors to WP do fall into that category.) There's a HUGE amount of peer-reviewed engineering literature on all sorts of mining, yet no such refs are given in this article. If my memory is correct, the subsidence reported in NSW was due to very old mines, which had been closed for decades. The usual practice in those days was to fill the mines with water, which stopped most of the cave-ins, but not all. 220.244.246.158 ( talk)
OK take a look at West Virginia retreating longwall mine. First of all, is this a top view or side view?!? I assume top view; would be nice if someone who's sure could insert that phrase.
The words "Barrier Pillar" are in white areas. Are these white areas the solid pillars themselves, made of coal? Or are they open-air places, and the dividers with rectangles in them are solid coal walls, and therefore the pillars?
The divider areas with rectangles in them: are they supposed to be conveyor belts, and therefore the divider areas are open hallways? Are they conveyor belts, loaded from miners in the open-air white areas?
Portion of panel worked out - worked out, you mean dug out and gone? Or, a mining engineer 'worked out' that this solid area is strong enough to use as a pillar? Is the shaded area full of coal or of air? What is the direction of digging?
longwall face just formed - do the words refer to the neighboring shaded area? Or to the white block it's in? Is the shaded area actually a 'face' - the plane between rock and air - rather than a space? Or is the face intended to be the right edge of the shaded area, immediately to the left of the words?
The Oklahoma picture is a lot better - there's a key in the image. The longwall before-conveyors, at least I can see from the arrows and the door that the thin parts are air and the thick parts are rock.

Yes it's all very small and no subsidence happens and everyone is happy. But what about the Mount Sugarloaf incident, I think it shows a better example of the sorts of things that can happen. [1] Healyhatman ( talk) 13:01, 19 April 2015 (UTC)

Hi, I have added sections to the longwall mining article, particularly involving the environment. There was only Subsistence, and I added sections to focus also on water quality, greenhouse gas emissions, and ecological impacts. Longwall mining is prominent in Canada so I went ahead and added a section on Longwall mining in Canada. Elasticat ( talk) 04:05, 10 April 2019 (UTC)
It appears that representatives of Anhui Feichun cable manufacturer are targeting this and other mining-related articles for edits that promote that corporation. I have reverted the article to its form prior to these edits. Silcantar ( talk) 17:08, 11 July 2024 (UTC)
