Overview

Numerical modeling assesses pillar strength and stress distribution in coal pillars with rock inclusions.

Key Points

  • Numerical modeling shows the effect of geological factors on coal pillar strength and stress distribution.
  • Stress distribution is analyzed using finite element methods across the mid height of the pillar.
  • Numerical models reveal interactions between rock inclusions and pillar stability factors.
  • The study emphasizes the importance of empirical design tools in estimating coal pillar strength.
