A waterproof granular explosive composition which like conventional ANFO explosive, is excellent in handleability, for example, being usable in bulk form and having fluidity and can be produced by an easy process, and which exhibits satisfactory water resistance in an immersion time envisioned in practical use and further exhibits explosion performance. In particular, an explosive composition comprising porous prill ammonium nitrate and a nitro compound optionally together with an antiblocking agent characterized in tha t a waterproof resin coating film is formed from a thermosetting resin and the above components are covered with the waterproof resin coating film.
