【Abstract】 The quality of presplitting blasting near the side slope could directly impact the stability of side slope as well as the safe productions and operations of mine.When organize and implement the presplitting blasting,the Φ165 slope drill should be used rationally in the edge explosion as well as the different blasting methods,hole pattern parameters and explosive charge in each hole should be adopted actively according to the different lithologies at various positions on edge of stope.更多还原
