Abstract: Based on the lithological character and geological environment of a mine in Yichang,and combined with the field rock burst characteristics and laboratory tests,the prevention measures are put forward after analyzing the main reason of the rock burst in experiments.The results showed that,①the rock mass of the mine roof which contains siliceous dolomite,has strong rock burst tendency under the horizontal stress environment.②The rock burst rate and intensity in mining area are bigger than that in roadway,as the geometric size of the excavation roadway is much smaller than that of the mining area,and the surrounding rock in mining area is affected from many factors.②The rock burst can be protected by reducing the stress concentration of the surrounding rock and strengthening the safety management measures,according to the special initial stress and the geological environment.
