摘要: FIELD: mining.SUBSTANCE: method of blasting rock mass includes preliminary zoning rocks by fracturing, mosaic structure and blastability thus determining elementary uniform sections subsequent updating during mine works. Elementary zones are formed size output slurry in near-wellbore corresponding height to three - location stemming, charge above below bench bottom. According characteristics parameters drilling operations determined, at that level used determine operations, stemming update operations.EFFECT: improving efficiency due reduction expenses losses wells caused rockfall, quality fragmenting development bottom.6 dwg
