ANALYSIS OF THE INTERACTION BETWEEN MOBILE ROOF SUPPORTS AND MINE STRATA (1998)

To provide a better understanding of the mechanics of strata deformation, the authors have collected and reviewed measurements of convergence and stress in one western U.S. mine and have completed pseudo-three-dimensional, boundary-element modeling for two typical pillar-pulling plans. Stress distribution in the mine roof above pairs of MRS's was calculated to demonstrate how MRS's contributed to the control of roof block movements
