Paper presented at the 1st North American Rock Mechanics Symposium, June 1–3, 1994
Paper Number: ARMA-1994-1017
... ABSTRACT ABSTRACT: The local mine stiffness concept has been investigated by a numerical analysis to provide guideline for longwall pillar design in bump-prone coal beds. The results show that local mine stiffness can be used in evaluation of longwall mine design and in control of pillar bumps...
