Longwall Mining

[@stickmonster24]

Fantastic description and simplistic animations to really explain it in layman's terms. Thank you very much for this!

[@itsacorporatething]

Does the ground above the mine sink down because of the coal excavated below?

[@aramdrake6960]

There is a lot of variables ie. Face width, depth of cover, extraction height and geological to name a few. Generally the surface does subside but can be designed to minimise the subsidence or eliminate completely if required. A worked example is a typical mine at 250meters depth 300 meter wide, mining a 4 meter seam may result in surface to subside 1 to 2.5 meters.

Yes

[@markbeale7390]

Depends on depth and strata strength above.

What software did you use for that animation design, I want to use it for my School Assignment,

Very well done !

underground long wall mining knowledge

[@lidarman2]

Looks like a mineral extraction engineer's job is all about optimization.

[@Obi-Wan_Kebobi]

yep,but also about safety!

Simplistic, yes. Accurate, no. There is more roof and pillar mining that's done prior to the longwall. You need more entries (or roads, as he calls them) and more equipment. There's better descriptions out there than this.

Вот так лава отрабатываеь пласты
