Summary
Core Theme
Coal remains a critical global energy resource, with massive underground mining operations like the Bailey and Enloe Fork mines in Pennsylvania employing advanced machinery and dedicated labor to extract and process millions of tons annually for electricity generation.

man has used coal as a fuel for over
3000 years and it remains one of the
world's most vital natural resources
generates more than 40 percent of the
world's electricity and every year we go
through six billion tons
somehow minds must ensure a constant
Supply or our cities would be plunged
Into Darkness and industries would grind
Pittsburgh Pennsylvania
this industrial east coast city is
famous for steel production and shipbuilding
shipbuilding
but Pittsburgh is also surrounded by
Rich coal reserves
and here just 30 miles from the city are
the bayley and Enloe Fork mines
this is the largest underground mining
complex in North America
and every year it produces more than 20
million tons of coal
there are millions of dollars invested
in this vast complex and with more than
200 men working underground at any one
time keeping it running is a major
at four in the afternoon the day shift
clocks off after eight hours of hard
work while the next shift makes its way
into one of the lift cages to begin the
650-foot descent into the mine
mining is one of the toughest jobs
imaginable and there's an unspoken bond
between these men who spend every
once they arrive at the bottom of the
shaft they still face a long journey to
after almost 20 years of continuous
mining a vast network of underground
tunnels now extends for an extraordinary
35 square miles the miners face a
five-mile journey to get to the section
it's a cramped and uncomfortable ride
aboard one of the mine's small trains as
the cars rattle their way through the
Maze of dark tunnels following a network
of rails that are now so busy they
first up is a monster machine known as a
continuous Miner
armed with a 16-foot cutting drum This
ferocious beast Chomps away at the seam
as it bores its way forward it feeds the
coal behind it to a crab-like loader and
The Continuous Miner produces up to five
tons of coal every minute more than a
minor in the 1920s produced in a whole day
day
but its job is actually to prepare the
way for the real monster the long wall Shearer
armed with a set of teeth to put a
tyrannosaurus to shame its Cutting Edge
is over one thousand feet long and it
can smash an amazing 50 tons of coal out
of the seam every minute
think about it that's almost one ton of
coal every second enough to meet all the
energy needs of an average household for
but there are three million tons of coal
in this 13 foot high seam
despite its ferocious appetite it will
still take six months of shuttling back
and forth before it has finished digging
before the coal is fit for shipping they
first need to remove Rock soil and
contaminants which account for up to 30
so the material is fed via conveyor into
the processing plant
ensure it's all properly processed it's
first graded according to size
next to separate the coal from the waste
rock it's fed into this giant flotation tank
because the rock is heavier than the
coal it sinks to the bottom where it can
be removed while the coal floats to the surface
it's now soaking wet so just like your
home laundry they load it into a spin dryer
this industrial dryer spins the coal at
high speed until excess water is removed
this water is then fed into vast tanks
where the contaminants are removed
meanwhile the different sized pieces of
coal are recombined crushed into a
incredibly just 15 minutes after
entering the plant it's ready for
transport by rail
as they Park beneath the hopper a
controller opens a chute to allow six
tons of coal to fill each car
once full every train is able to
transport over ten thousand tons of coal
to some extraordinary cold crunching
machines and the guys who labor 24 7 to
keep them working this essential
resource keeps flowing to the world's
power stations and there's enough
electricity to power the wheels of the
