Structural behavior of ground around underground openings; 2 types of rock structures which are capable of supporting themselves to span mine opening, are beam and arch, pressure arch, front and rear abutments; avoidance of squeeze on timbers by limiting length of stope to span less than that of pressure arch; application of yield pillar techniques to room and pillar methods at depth; yielding supports for squeezing ground; application of yielding arches and rings.
