Stress Determination in Rock Mass with Regard to Sequence of Deep-Level Cut-and-Fill

The article discusses application of the deep-level stress determination method developed for modeling stress redistribution in rocks and in backfill as mining operations are advanced. It is suggested to take into account elastoplastic properties of rocks and backfill using the stiffness matrix of i...

Description
Summary:The article discusses application of the deep-level stress determination method developed for modeling stress redistribution in rocks and in backfill as mining operations are advanced. It is suggested to take into account elastoplastic properties of rocks and backfill using the stiffness matrix of intact rock mass. The illustrative calculations are presented.
