Machines make mining easier, quicker, and
sometimes safer. Here are
some of the machines used in mining:
Wheel loaders: These are used when a lot
of mining materials need to be moved at one time.
Excavator: Most surface mines have one of
these. This machine is used to do the digging.
Usually this machine dumps the materials that it dug up
into a dump truck.
Dump Trucks: These are used to take
away or move materials. You can see how big it is
compared to the driver. Sometimes these are called
monster trucks because they are so big.
Crawler-tractor [bull dozer]: Sometimes these are
called dozers. Instead of rubber tires, these have
chains. Chain tractors are used on land where
rubber tires won't work too well--like in mud or on
mountain slopes. Dozers push dirt from one place
to another. When mines close and they begin to fix
the land that has been changed, dozers push dirt and
materials where they need to go.
Motor grader: These are used to
make the ground level when they are clearing off the
land for mining or fixing it when they are done.
Articulated Dump Trucks: These are
used to move large amounts of material in the mine.
They can turn easier inside mines than most trucks can.
Continuous miner: This machine is
used to cut out long sections of the inside walls of the
mine. They use this machine instead of blasting
Longwall mining equipment: This is
used to cut out the coal in layers. Part of the
machinery will hold up the roof, too.
Shuttle car: These were used to
take out the coal or minerals from the mine. They
look a little like our buttons on the left, but not
colorful. The ore or coal was loaded into these to
be taken out of the mine. Trucks are used for this
in up-to-date mines.
