ABSTRACT:
The present invention comprises a permissible aqueous blasting composition containing at least about 15% calcium nitrate as oxidizer salt. The calcium nitrate combined with water, inert material, a sensitizer, and cross linking and thickening agents forms a stable aqueous blasting composition or slurry which will meet the permissibility requirements of the U.S. Department of Labor. The use of this minimum amount of calcium nitrate particularly is effective in increasing storage stability.
