    摘要: The present invention provides an explosive method that improves on methods currently employed. The present invention provides for a safer, less expensive, and more portable explosive device. The elements of the present invention replace dynamite or similar explosives currently used in avalanche control and bore hole blasting of rock or other solids. The present invention comprises an apparatus and a method providing a much safer alternative employing a highly confined combustion reaction of a flammable vapor, whereas dynamite is a category 1.1 high explosive imbued with all the attendant safety and security concerns. The method of the present invention provides for an improved and safer method of blasting employing a highly confined combustion reaction of a flammable vapor instead of conventional explosives currently used.
