Heighten seismic prospecting res olution is a systematic engineering, must u se different means on field collection and processing of informations, thereby reach the purpose to heighten resolution. There a re special effect on heighten seismic prosp ecting resolution, with explosive source o f low blasting speed and slender shape. In t he research found that receipt of longitudi nal wave and transform of shear wave meanti me, correlation with high blasting speed Ex plosive source, the explosive source of low blasting speed and slender shape may be eff ectively advanced-cut band(band of longitu dinal wave reach more than 220Hz), and heig hten reflection basic frequency of target s tratum (basic frequency of longitudinal wa ve reach more than 120 Hz). Spread applicat ion of explosive source of low blasting spe ed and slender shape in the seismic prospec ting, it will be sure to heighten effective ly seismic prospecting resolution.
