چکیده:

Rockburst is a common dynamic disaster of mine in deep surrounding rock, which occurs with rock fracture and falling even casting phenomena during or after the roadway excavation. With the increase of mine depth, rockburst becomes one of the serious disasters which bothering the safety of the coal mine production. Nowadays the analyses of rockburst mostly focus on its mechanism and prediction also the prevention measures three aspects, which have achieved lots of progress. But fewer analyses pay attention on the whole procedure of rockburst which contains its occurrence and development. Analysis on the whole procedure of deep surrounding rock coal roadway responses under dynamic disturbance which based on the surrounding rock initial stress environment and the dynamic disturbance intensity and dynamic disturbance duration three related factors are constructed respectively by using the discrete element method software UDEC, moreover the transfer and dissipation rules of energy in the surrounding rock are concluded from the simulation. Those all discover a more profound and visual image of rock burst
