Abstract
The present invention is directed to an improved method of blasting whereby the formation of nitrogen oxide after-blast fumes is reduced. This helps satisfy the need for better fume characteristics in blasting. The method reduces the formation of nitrogen oxides in after-blast fumes resulting from the detonation of a blasting agent in a borehole. The method comprises formulating the blasting agent to contain from about 1% to about 20% silicon powder.
