Seit 2015 gibt es dieses video es kommt zu spät das kann man ja nur noch in Ausland anbieten aber nicht mehr hier in Deutschland
wonder how much one of these machines costs
ну и как обслуживать конвейер ?
Does this machine get teleported into the ground magically underneath all the rock/coal? I wonder how it gets there inside everything.
I can't understand where is the operator when the machine is running
Ни хуя не понял, но было интересно
This is bit confusing
yea you deserve my dislike 👎
I love u CAT so nice in I like you so much
Oh ok this makes me understand coal mining a whole lot less...
That rear chain looks like it would be a constant problem. And how would you free it up if it gets stuck or even replace chain without pulling the whole wall. Or hell even recover it. Looks difficult
To really collect all the coal that others left behind, CAT's magic is at 2:20 lets pretend that all the remaining leftover coal is rocks, and we can just happily pretend we didn't left any!
Very highly automated system requiring only a few highly-trained operators ... remind me again of how renewable energy "killed" all the low-educated but well paying mine laborer jobs? Just as well in my opinion, as such jobs are among the most unhealthy and dangerous in the world, getting laborers out of mines is a good thing, even if they do have to find other jobs.
Tnx for this YouTube
Just wait till they hit redstone
I dont understand. Firstly, how the machine can get underground? Where is the hole?
It would take a running start with a 15 degree downhill slope for one of these to break the crust on Hillary Clinton's vagina

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.


Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008. In early 2015, it was trading near $56/ton.
