hi I'm Chris wit with Virginia
Department of Mines minerals and energy
and this is your mine safety minute
today we're out here on impoundment
construction checking things out and we
have a good viewpoint right here of the
upstream base construction of the dam
so from this vantage point we can see
the upstream construction of the dam we
can see the face of the dam we can check
it for any irregularities any slips or
slides that might have occurred or any
erosion due to heavy rainfall one of the
nice things you can see here's the
discharge lines the way they're spaced
out so that the material can be spaced
out evenly across the bottom of the dam
a proper Beach area at the toe of the
dam is very important to safety it helps
protect the face of the dam form any
wave action that might occur in the
water and it also helps during
construction to lock everything together
and make it watertight
