Disposal of obsolete munitions is a permanent process, during which colloidal gunpowder are liberated and accumulated. Especially large quantities of such materials were accumulated in the countries ofthe former Soviet Union, including Georgia. Warehousing and storage of such materials and/or direct application may cause a serious threat/risks in terms of ecological and unauthorized use. Therefore, today’s colloidal gunpowder is mainly stored and the expenses of their storage permanently increase, in addition, there is a permanent threat of their unauthorized use, because they belong to the class of explosives. The long-term storage of the overdue gun powders and rocket fuels contains self-blasting risks. So, this problem is urgent at the local and global levels. Traditional ways of problem solution area simple creation of new explosive materials on the base ofthe application of ingredients possessing better properties. In distinct from the traditional methods, the essence of the offered works is a creation of new type industrial explosive compounds and application of fuel removed from utilized missiles/shells of military designation in the role of components of explosive materials. A number of hints have been identified in the process of studying the exploitation of industrial explosives on the base of gunpowder and solid rocket fuel. They have created a prerequisite that the cartridges made on the basis of colloidal gunpowder can be initiated using the malware. This method of initiation allows us to a gradual increase of the gas pressure in the chamber of the critical size at which the pressure of the gas will break through the impact of the shaft and thus the breaking of the rock. In the process of research, explosives characteristics of pyroxylene and ballistic fuel mixtures have been studied. It was established that the granulomatrium composition of the mixture is significantly influenced by these characteristics. For example, if the diameter of the granules varies between 3-20 mm, the reaction of the collapse of the mixture is carried out steadily with blast mode, without switching to the detonation. If 10% or more granules in the explosive mixture are smaller than 1 mm, the combustion process can be transferred to the detonation.
