摘要： A method of designing supports for an underground mine opening comprising the steps of: receiving mine slope information including at least one of site location, entry length, entry grade, entry orientation, size of opening, surface topology, adjacent borehole data and rock mechanics test data, historical roof fall height, and expected steel set support capacity; conducting stress and geological condition evaluation of the mine opening using a finite element computer modeling program based on the mine opening information; and designing structural supports for the mine opening utilizing the stress and geological condition evaluation of the mine opening.
