EXPLOSIVES FOR CONTROLLED BLASTING THAT NOISE AND VIBRATION IS SMALL AND FLAME AND AFTER EXPLOSION IS NONE, ESPECIALLY NITRATE-SACCHARIDE EXPLOSIVE

摘要

An explosive mixture is provided to occur no fire by flame in blasting because flame and post-explosion are not generated, to generate little noise and vibration because an explosive rate is befittingly slow. An explosive mixture includes oxidizer of 5 %~95%(weight%), fuel of 2%~50% as main components and speed decreasing agent of 0%~80%, sensitizer of 0%~20% and desensitizer of 0%~20% as additives. A speed of explosion at confined state is 10m/s~1 000m/s. An O.B. of gunpowder is -5%~+50%. The oxidizer is nitrate(MNO3). The speed decreasing agent is ferric oxide(Fe2O3), the sensitizer is sulfur(S) and the desensitizer is light oil(CH2), liquid paraffin, vaseline.
