Q183

In a surface mine blast, the peak particle velocity (V in mm/s) is estimated from the equation V = 120 ( SD )^ - 1.0, where SD is square root scaled distance. If at a distance of 100 m from the blast site the permissible peak particle velocity is 25 mm/s, the maximum charge per delay in kg is
