Abstract
A method of blasting using non-nitrogen containing explosives which protect the environment from pollution of nitrogen compounds is provided. The method includes the following steps: (1) combining an oxidizer, a fuel, water, and a binder such that an explosive is formed which is substantially free of nitrogen; (2) placing the explosive in a location selected for blasting; and (3) initiating said explosive. The nitrogen-free oxidizer may be a perchlorate such as sodium perchlorate. Using this method, the explosive may be a water gel, emulsion, a dry explosive, or a liquid oxygen explosive.
