STUDY OF ROCKBURST BASED ON THE HIERARCHY OF ROCK MECHANICS SYSTEM
This research aims to the mechanism of rockburst in Haizhou coal mine. The numerical simulations were used to get the geological structure environment, mining induced stress and failure of roadway. The geological structure - sediment system, coal - rock system and floor strata system are divided and the hierarchy and nonlinear of them are discussed. The research shows that Gaode syncline is an inhomogeneous factor and the nearer the roadway is to Gaode syncline, the higher is the stress. This is the reason that rockburst closed to Gaode syncline. The interlayer in roadway make the stress of roadway to increase to 3~6 MPa than the case of no interlayer. So when rockburst occurs, the floor heave is main way of failure of sounding rock.
