Abstract
Abstract SELF-STERILIZATION CAPABILITY IS IMPARTED TO A CHEMICALLY ORIENTED MINE BY THE INCORPORATION INTO THE ACTIVE EXPLOSIVE OF A MATERIAL WHICH IS HYGROSCOPIC AND DELIQUESCENT. THE LATTER MATERIAL ABSORBS MOISTURE FROM THE ATMOSPHERE AND DELIQUESCES INTO AN AQUEOUS SOLUTION WHICH REACTS WITH THE ACTIVE EXPLOSIVE RENDERING IT LESS SENSITIVE AND ULTIMATELY STERILIZED AND SAFE TO HANDLE.
