Abstract:
Numerical schemes for determining the shape and dimensions of radial cracks formed during confined explosions of linear charges located in a monolithic rock massif at a great depth and near its surface. The influence of the charge length on the dimensions of radial cracks in a confined explosion is studied. The amount of undercharging of a borehole or blast charge for which the area radial cracks is maximal is determined.
Keywords:
explosion, borehole charges, blasthole charges, radial crack, crack shape, three-dimensional modeling.
