METHOD FOR CONTROLLING BLASTING OPERATIONS Abstract of the Disclosure A method for predicting the ground vibration and airborne noise at any position resulting from a blasting operation using the data obtained from one or more single-charge low level blasts. By using convolution in the frequency domain, large charge weight nonlinear vibrations are considered, such that the optimum excitation frequency (detonation delays) is induced for minimizing objectionable ground and air vibrations and noise. The method also allows optimization of the number, position and loading of the blast holes, and the number and position of charges detonated per delay period to produce maximum removal of material without damage to surrounding structures.
