The invention relates to the technical field of engineering blasting, in particular to a water medium transduction shaped charge blasting device which comprises a closed water bag, and the closed water bag is filled with water and arranged in a blast hole needing to be blasted in a sealed mode. The explosive is located in the blast hole and arranged on the side, close to the bottom of the blast hole, of the closed water bag; the energy gathering piece is arranged at the bottom end of the blast hole; wherein the energy gathering piece, the explosive and the closed water bag form a double-function blasting system in the blast hole, the double-function blasting system can conduct blasting twice within the set time, and the explosion energy in the blast hole can be fully utilized through the arranged double-function blasting system, according to the first blasting system, water medium transduction blasting is achieved through arranged explosives and water in a closed water bag, so that the blasting time interval
