CDC Mining Feature Inundations Can Put Miners at Risk

Mining next to one of these sites can be dangerous if the new mine workings break into an older mine that is flooded. This can be avoided by drilling ahead with a small probe that could expose a possible flooded drift in an adjacent mine, so as to avoid exposing the flooded area to the newly mined area.
