Disclosed herein is a rock blasting method using air bladders embedded in explosives. The rock blasting method includes the step of drilling a plurality of loading holes into a rock to predetermined depths in a predetermined arrangement. Thereafter, the loading holes are loaded with a plurality of initial explosives, a plurality of primers and a plurality of explosives in such a way that one or more air bladders are inserted into each of the loading holes and surrounded by the explosives. Thereafter, the loading holes are stemmed with stemming materials in the portions of the loading holes situated over the explosives. The primers are detonated so that the initial explosives and explosives are blown up. Hence, the loading lengths of the explosives are increased in proportion to the lengths of the air bladders so that a projection area formed on the free face of the rock is increased.
