The results show that the characteristic of acoustic emission is closely related to the load variation or the deformationfracture of rock.
结果表明，声发射与载荷变化或岩体变形破裂密切相关。

Brittle fracture. Fracture that occurs by rapid crack propagation and without appreciable macroscopic deformation.
通过快速裂纹扩展发生断裂，没有明显的宏观变形。

In mining engineering, strata models are often simulated by similar material simulation model, rock bending deformation and fracture damage is the serious problem.
