I'm Andy Sawyers with Virginia energy
and this is your mind safety minute
today we're going to be talking about
ventilation practices in underground
coal mines we have several different
tools that we use to make sure that the
mine is properly ventilated this is an
anemometer and it's used to make sure
that air is moving in and out of the
mine and in and out of the place where
miners are working
this is a Magna helic gauge Magna helic
tells us what the pressures are in a
given area to decide if we have any kind
of a restriction in that area to airflow
for smaller spaces or confined areas we
use this pedo tube to be able to get
measurements that we couldn't get
remotely the quality of the air in the
mine is just as important as the
quantity of air in the mind this is a
multi-gas detector that tells us what's
in the air such as oxygen Co or methane
