Application of deconvolution to blast vibration control

Deconvolution is a signal processing technique commonly used for the separation of components of a waveform. This paper deals with the application of deconvolution to blast vibration signals. The homomorphic deconvolution process takes place in the frequency domain as well as its inverse transform is carried out after converting the linear scale into the logarithmic form. As a result, the method provides the impact force of the microdelayed explosion from response measurements. The immediate application is the vibration control; once the transmitted impact force is known, the blast may be designed to prevent accelerations exceeding the safety limits in such a way that it may take advantage of the constructive interference of the seismic waves.
