[0037] The working principle of a mining solid waste product backfill treatment system and a directional backfill device provided by the present invention is as follows:

[0038] The mining solid waste products are crushed by the crushing system, and the crushed mining solid waste products are transported to the separation system to be separated into two products: fragments and granular powder;

[0040] Compared with the related art, the mining solid waste product backfill treatment system and directional backfill device provided by the present invention have the following beneficial effects:

[0041] By crushing and separating the mining solid waste products, the mining solid waste products can be broken into smaller pieces and backfilled into the tunnel, so that more mining solid waste products can be filled in the tunnel, reducing the gaps in the tunnel, and then the granular powder separated from the mining solid waste products is backfilled into the pit, so that the granular powder can fall into the gaps in the broken pieces, fully backfilling the tunnel, reducing the gaps in the tunnel, and avoiding collapse and hollowing after the tunnel is backfilled.
