The thermo/viscoelastic analyses predicts a maximum drillhole surface pressure of approximately 3,000 psi after one-half year of heating, assuming the drillhole surface is fixed against radial displacement. With the drillhole surface free to displace radially, the radial displacement is observed to be about 1.5 inches after twenty-five years of heating, for a total drillhole closure of 3.0 inches. In this particular case, with the centerline of the pillar being a line of symmetry, the material expansion upon heating forces the salt upward and into the room and drillhole areas. (20 figures)
