The invention discloses a drill-hole cleaning free blasting charge structure adopting a VCR mining method and a construction method of the drill-hole cleaning free blasting charge structure. A blasting segment of a blasthole is filled with multiple layers of explosives in a layered manner. The explosives are spaced by particle filler. The explosives are guided out of the blasthole through a detonation assembly to be connected with a detonation network. The length of the explosive at the topmost layer is smaller than the length of the rest of layers of explosives, the position, above the explosive at the topmost layer, of the blasthole is filled with particle filler, and the position, above the particle filler, of the blasthole is filled with a water column. The reasonable and scientific charge structure is adopted, the combined blocking structure of a small quantity of explosives, particle blockage and the water column is adopted on the upper portion of the explosive on the top layer,the phenomenon of hole blocking of the top non-blast segment is effectively eradicated fundamentally, the additional economic cost caused by the drill-hole cleaning workloads due to blasting hole blocking is saved, the production construction period is prevented from being delayed, and the negative effects caused by large-charge-mass blasting in the VCR mining method are greatly reduced.
