Abstract Based on the study of rockburst distribution in China，the rockbursts are classified to the coalmass compressible type，roof crack type and fault dislocation type. The mechanism of every rockburst type is studied respectively. Based on these study，the effective measures preventing rockbursts are put forward. The measures preventing rockburst of coalmass compressible type are to change properties of coalmass by coal seam effusion，unloading by exploding，mechanical vibration for rockmass crack and so on. The measures preventing rockburst of roof crack type are to change roof movement rules by mining liberation layer，high-pressured water-jet cutting for liberating coal seam itself，pillar remaining and so on. The measure preventing rockburst of fault crack type is to confine fault movement.
