The problem of modeling the industrial explosion for a vertically inhomogeneous medium has been considered in general form. An algorithm to transform the wave field to a pulsed form, which uses a priori information about the spatial distribution of charges and delay times in the quarry explosion, is proposed. The distributed short-delay explosion is considered as a set of point sources of one type located at the same depth under a surface with an arbitrary distribution on the plane. Each source is characterized by its own time function and its own delay time. Recording of the seismic signal from an explosion at a profile in the far zone, that is, at distances much longer than its typical size, is considered. The process of formation of a seismogram from a distributed explosion at the profile is investigated, and an algorithm to reduce it to a pulsed form is proposed. In the space-time domain, a pulsed seismogram is obtained after the 2D inverse Fourier transform. The transformation function is determined as the product of the spectra matrix of individual explosions with vectors of phase delays in the frequency and wave vector.
