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

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.

Depends on depth and strata strength above.

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

yep,but also about safety!

Good

Wow😘❣️

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.

load coal!!!!!!!!!!!!

Very interer

can't understand the accent

Please tell clearly your voice/ slang is not good

Nice video but your speech is intelligible.
