Abstract
A method for designing and fabricating a mine seal includes determining an initial thickness for a mine seal based on a predetermined underground opening, developing and solving a numerical model for response of the mine seal upon application of a blasting pressure, and determining whether the mine seal meets predetermined design criteria. A mine seal having a minimum seal thickness may be fabricated after determining the mine seal meets the predetermined design criteria.
