Low-detonation-velocity high-brisance explosion cladding explosive and use method thereof

The invention discloses a low-detonation-velocity high-brisance explosion cladding explosive and a use method thereof. The explosive is formed by mixing rock type powdery emulsion explosive, industrial salt, hard wood power and talcum powder. The explosive is stable in detonation and is low in detonation velocity by test. By the use method disclosed by the invention, the high brisance can be achieved, thereby ensuring the quality of explosion cladding. In the explosive disclosed by the invention, the proportion of the original explosive is reduced, and the ratio of cheap auxiliary material is increased, thereby reducing the cost. According to the invention, the mixing method is simple, the explosive is free of high explosive and non-caking and has long effective time, and various raw materials do not hurt human health.
