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 explo...


[ What is claimed and desired to be secured by Letters Patent is:] [1.] A method of blasting employing commercial or mining explosive compositions, while substantially eliminating the emission of nitrogen during the use of such explosives, comprising the steps of:formulating an explosive composition comprising a substantially nitrogen-free oxidizer and a substantially nitrogen-free fuel said explosive consisting essentially of from about 45% to about 60% of at least one nitrogen-free perchlorate; from about 15% to about 25% fuel; from about 20% to about ...
