VISIT
TO THE OPEN CAST COAL MINE
On
October the 30th, after lunch we went to Gargallo to visit the coal extraction
pit.First of all we called at the ENDESA offices, the names of the ENDESA
mangers, who explained to us about the mines, were Joan and Francisco.
Francisco
talked to us about the kind of plants that after refilling the pit, they
are going to plant: pine trees, rosemary, Thyme.
They
showed us a stone that came from coal, and later Joan explained to us
about where coal came from. Coal came from tree trunks and plants that
got buried many years ago.
Before
going into to pit, we had a look at a scale model of it.
After
that we went to a view point to see the diggers extracting coal, and we
also saw how the trucks from "Alfonso Company" were loaded with
coal, to carry it up to Andorra coal Power Station.There was also a tractor
pulling a water tank, this is used for wetting the ground when there is
too much dust.
We
saw the different colour layers of soil and coal.
At
the view point we had photographs taken with our guides.
Later
we visited a workshop were dumpers and diggers get fixed. We had another
photograph taken next to a dumper to appreciate how big they are.
After
that we got into the shovel of a mega excavator and had another photograph
taken.
