Abstract : Recently, to perform seismological prospecting using electronic computers, the authors began to calculate the shape and spectral composition of reflected waves formed in an assigned stratified medium - a model of an actual cross-section. Therefore, it was necessary to know the shape of the incident wave, i.e., the shape of the elastic impulse emitted by the blast. To accomplish this works were set up to study direct waves near the earth's surface using a vibration excitation procedure common for seismological prospecting, i.e., using bore-hole explosions at a depth to several tens of meters.
