Study of property-changing of ammon-dynamite

Ammon－ dynamite is widely used in demolition engineering . It's application field can be expanded so that it can adapt to the demands of the blasting agent of the special demolition engineering by adding right property－ changing agent in it . In this thesis , the appropriate proportion of the property－ changing agent is gived and the adaptation of the mixed blasting agent is examined on spot by the example of the study on the "weak dynamite" in stone exploitation.
