Abstract

Abstract

In order to study surrounding rock deformation and fault activation caused by underground mining, a small-scale model of soft materials is adopted to simulate the s discontinuity plane deformation induced by underground mining. The bending of a horizontal discontinuity plane after activation is studied through the model by simulating the deformation of the surrounding rock at the top of a rectangular underground mining area. The simulation results show that the shear displacement distribution on the discontinuity plane has the feature of bimodal curve, which is verified by numerical simulation. At the same time, the validity of this method is proved. The biggest advantage of this method is that the small-scale model can effectively simulate the deformation of surrounding rock caused by underground mining under the action of self-weight stress, with simple experimental equipment, short time, convenient operation and low cost. It is a physical simulation method worth popularizing.
- small-scale model,
- structural plane,
- bimodal curve,
- self-weight stress,
- underground mining,
