A methodology for lining design of circular mine shafts in

In this study, a new methodology for lining design of circular mine shafts in different rock masses is developed. A parametric study is carried out using the finite element numerical modelling of 2D shaft sections in a HoekBrown Medium in a non hydrostatic stress state in an attempt to predict the pressures developing around mine shafts.
