Numerical analysis on stability of surrounding rock mass around deep roadway

Journal of Coal Science and Engineering (China), 2011
Numerical simulations of the deep roadway were carried out through application of the strain-softening constitutive model. Differences between the deep and shallow roadway of the rock bearing structure were analyzed. Influences of the supporting resistance on the rock bearing structure at the deep roadway were discussed.
