Abstract:Pressure bump mostly occurring in developing workings is a hazard posing severe menace to mining operations. An analysis is made of the mechanism of such hazard from various aspects including mining methods, distribution of stress in coal mass, support intensity and mining disturbance . Precaution measures to combat the hazard are proposed .
Keywords:elastic energy  superimposition effect  stress concentration  trajectory impact  accumu- lation  triggering
