A blasting treatment method for treating, by blasting, an explosive having a powder and a chemical agent in a closed pressure vessel capable of preventing soot from occurring in the blasting treatment and increasing the decomposing efficiency of the chemical agent. First, a carried chemical bomb (explosive) (100) is put in blasting chamber (pressure vessel) and sealed. Next, after air is exhausted from the blasting chamber (10) by using a vacuum pump (13a) to bring the inside of the chamber into a vacuum state, oxygen corresponding to 15 to 30 vol.% of the oxygen contained in the atmosphere is fed from a filler (12) into the blasting chamber (10). Then, the chemical bomb (100) is ignited by an unshown ignition device for the blasting treatment. |
