Abstract:
For calculation of height and width of blasted materials, as well as, width and height of retaining wall during blasting of hole charges with usage of emulsion blasting
materials, formulas are obtained which contain main parameters, defining energetic characteristics of emulsion blasting materials, physical-mechanical features of rocks and
parameters of blasting block.
Keywords:
borehole charge, camber width and height, emulsion explosives, formulas, energy characteristics, physicomechanical properties of rocks, parameters of an
exploded block.
