    Design of underground openings in competent rock

    New search for: Obert, L.
    New search for: Duvall, W.I.
    New search for: Merrill, R.H.

    Design principles for openings and pillars in massive formations are obtained by considering maximum tangential stresses as developed around single and multiple openings for stress fields of various types; design principles for openings and pillars in bedded formations are obtained by considering average stress in pillars and maximum stresses in roof layers; experimental procedures.
