The utility model discloses a kind of 48 millimeter detonation bomb of deterrent type hand-throwing type riot, including firing mechanism and medicine box mechanism, firing mechanism includes fuse body, grip piece and needle prick delay detonator, still movably connected with pin shaft and split pin on fuse body, still connected with spring and firing pin block assembly on pin shaft, firing pin block assembly includes firing pin and turnover block, firing pin block assembly has first position and second position, when first position, spring is in compression state under the action of turnover block, and spring reset can drive firing pin block assembly to rotate from first position to second position;Split pin is connected with pull ring;Medicine box mechanism includes shell, inner medicine box and end cover, inner medicine box is filled with detonating agent, needle prick delay detonator extends into detonating agent, filling chamber is opened in shell, filling chamber is filled with paraffin wax.This scheme can emit greater sound and strong light, suitable for use in vast space, and can carry out more accurate strike.

This utility model discloses an auxiliary charging structure for open-pit water-bearing blast holes, including a water-bearing blast hole and an auxiliary charging mechanism. The auxiliary charging mechanism further includes a longitudinal guide cable, a counterweight, emulsion explosive rolls, a detonating cord, a transverse fixing cable, and a plugging section. The bottom end of the longitudinal guide cable is connected to the counterweight, which is located at the bottom of the water-bearing blast hole. The top end of the longitudinal guide cable extends to the outside of the water-bearing blast hole. Several rolls of emulsion explosive are wrapped from bottom to top on the longitudinal guide cable above the counterweight via the transverse fixing cable. Each roll of explosive also contains the same detonating cord, the top end of which extends to the outside of the water-bearing blast hole along with the longitudinal guide cable. The plugging section is located at the top of the water-bearing blast hole. The function of this utility model is to provide an auxiliary charging structure for open-pit water-bearing blast holes, thereby optimizing the charging structure, improving blasting effects, and reducing the residual explosive rate.
