- coal pillars failure, finite element method, excessive deformation
The methodology for calculating the dimensions of failure zones in coal pillars is proposed. The suggested approach is based on the finite element method, taking into consideration excessive deformation of coal seam, and compressive strength of coal. The estimation algorithm is suggested for the failure zones. The correlation between the failure zone length and the seam thickness as well as the mining depth is given herein with respect to various coal compressive strength values.
