Abstract The mechanical model of shock waves propagation is investigated when linear charge explosive in blasting chamber. The model is thought about many influence factors such as the length of linear charge, detonation velocity and air pressure that affect the flow field of blasting.
The reflection of blast pressure on the inner face of chamber is computed based on this mechanical and computation value is in good with experimental value.
