The invention provides an explosive charging device capable of realizing wide-pressure gas flow control and a design method thereof, the explosive charging device comprises an explosive charging pipe, a first through hole is formed along the central axis of the explosive charging pipe, a plurality of second through holes are formed along the circumferential direction of the first through hole, and the space outside the first through hole and the second through holes in the explosive charging pipe is filled with gunpowder; one-time casting forming can be achieved by filling gunpowder into the charging pipe, manufacturing of the grain can be completed through a one-time coating process after forming, the first through hole and the second through hole provide a combustion face, the charging coefficient of the charging pipe is high, and in the same charging pipe space, the effective charging amount of the charging pipe is far larger than that of multiple pieces of tubular gunpowder. Therefore, the area increasing
