aquifer rock or rocks prone to create voids or
which it was ascertained old mines that can not reliably be drained, or
mine, in which the morphology of the surface is a prerequisite to the formation
dangerous flood wave threatening underground mine (at excessive rainfall
etc.). Potentially breakout mine water is also mine, which already
water breakout occurred or which is located in the same or similar conditions as
