Abstract

Simulation-based finite element method of forming the features of the stress-strain state in pillar at the ore body downstream horizontal layers with a mined-out space. The obtained regularities of redistribution of stresses in pillar and surrounding rock massif are allowed to substantiate an effective way to reduce the bump hazard in mining  operations.
