摘　　要：An experiment model, scaled 1: 1, designed for studying a blasting method to clear away soot in a soot-delivery pipe in coal-burning power plant is described. By mixing RDX and Nitramon on a particular scale and sticking the explosive cartridge on the outwall surface of the pipe, the experimental result makes clear that the controlled blasting method can get rid of the soot effectively. Under the action of the blasting compression wave and reflectance tension wave,the soot is destroyed effectively in the region of - 60° ~60° around the bIasting site, that creates a condition for the second blasting in the surplus soot.An experiment model, scaled 1:1, designed for studying a blasting method to clear away soot in a soot-delivery pipe in coal-burning power plant is described.
