Description 307-311
This paper introduces a hybrid method of partial extraction by combining widely used methods, wide stall method for big
pillar and pillar splitting method for small pillar. Stability criteria for proposed method ensures stability and non-violent
failure condition of pillar. Numerical simulation of underground coalmine was carried out by finite element method (FEM)
and boundary element method (BEM). Coal pillars were simulated by FEM to determine stress-strain behaviour. Coal panel
was simulated by BEM to determine local mine stiffness and superimposed load on simulated coal pillars.
