Zusammenfassung:The utility model discloses a blast hole charging structure for mining and blasting, and belongs to the technical field of mining. The blast hole charging structure comprises a plurality of blast holes which are formed radially, wherein the blast holes are formed radially by taking one point as the center from the inlets of the blast holes to the bottoms of the blast holes; an initiating explosive tube, a detonating fuse and an explosive are arranged in each blast hole; each initiating explosive tube is arranged at the bottom of each blast hole; each detonating fuse extends out of each blast hole from the bottom of each blast hole; each blast hole is provided with a blocking part; each blocking part is 0.5-1.2 meters in length; the blocking parts of adjacent blast holes are 0.5 meter and 1.2 meters in lengths respectively and are staggered away from each other, so that excessively dense explosives are prevented from being charged into the blast holes. The blast hole charging structure has the advantages of si
