In order to ensure the safety of long-wall mining over an old rib pillar mining area,the stability of interlayer rock body under the action of mining-induced pressure needs to be evaluated and rational technical parameters for the long-wall mining determined.

Numerical modeling of flexural deformation of laneway in layered rock mass;

Deformation of huge underground opening excavated in layered rock mass with steep dip angle;

Stability analysis and anchor methods for blocks of underground layered rock mass in cavern excavation;

Study on integration of three-dimensional modeling and numerical simulation for stratified rock mass;

Excavation response of tunnel in stratified rock mass based on Hoek-Brown criterion

A definition of water-inrush-factor was presented,and the criterion about the instability of seepage flow of water in stratified rock mass was described by water-inrush-factor.
