The invention is suitable for the technical field of unmanned mining, and provides an unmanned mining-based mining packaging device which comprises a first conveying belt, a crushing 
assembly and a material distributing 
assembly are arranged on the first conveying belt, a second conveying belt is arranged at the 
tail of the first conveying belt, and 
coal conveying boxes are regularly arranged on the second conveying belt at intervals. A top cover electric cylinder is fixedly connected to one side of the second conveying belt, a supporting frame is fixedly connected to the other side of the second conveying belt, and a cover pressing electric cylinder is fixedly connected to the supporting frame; the smashing 
assembly comprises two smashing units which are oppositely arranged, each smashing unit comprises a roller, the rollers are provided with protruding threads, and supporting shafts are arranged at the two ends of each roller. In this way, large 
coal blocks can be smashed, the 
coal can be conveyed at intervals according to the capacity of the coal box, the quantity of the coal in the coal box is ensured, automatic coal boxing can be achieved, and manual operation is reduced.
