Abstract: To justify an effective method of protective pillar extraction, the destination of which has lost relevance, it is required to assess their strength condition. This problem was solved by the finite element method using the developed procedure. The obtained results made it possible to estimate the dimensions of the destruction zones in the pillars taking into account their mutual disposition, depth of occurrence, structure, deformation, and strength properties of the rock strata.

Key words: finite element method protective pillar zones of destruction in the pillars
