Research on prevention of rock burst with relieving shot in roof

摘要：

　　During hard roof rupture or slip instability with the sudden release of large amount of elastic energy,rock burst will be caused by violent shock easily.Based on the geological conditions of 6303 working face in Jisan Colliery,numerical simulation was carried out systematically of relieving shot in roof,then the reasonable parameters of relieving shot was provided.The results of danger-breaking measures of relieving shot in roof on-site shows that the danger of rock burst is reduced with fractured circle connected and values of electromagnetic emission and drillings decreased.
