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.
The influence of the front clean up of stress-strain state around a vertical mine of a tectonically fracture massif for a uranium deposit «Antey» is considered. By means of computer simulation it’s have been confirmed by field observations.
