Aim To resolve the question of recycling the waste nitric acid from explosive plants. Methods Firstly make waste nitric acid into urea nitrate by chemical synthesis

and then produce industrial explosive power by cool mixing. Results Industrial explosive is produced

whose main composition is urea nitrate and nitroamine

in which urea nitrate is a sensitizer. Conclusion This explosive

whose energy and strength are comparable to those of 2# rock explosive

is of low cost

low toxicity and with wide exploitive prospect.
