Blockage removal device for effectively removing ore-pass blockage

The utility model discloses a blockage removal device for effectively removing ore-pass blockage by large rocks. The blockage removal device comprises a tow rope conduit and a tow rope, wherein the tow rope passes through the tow rope conduit to fix an explosive substance. With smart assistance of ore-pass passages matched with an ore-pass, an ore-pass passage above a blockage point is utilized to determine the position of the blockage point and set the explosive substance, an ore-pass passage above the blockage point is used to determine a drilling direction. The opening of a guide hole is set below an obstruent (and close to the obstruent), and the explosive substance can smoothly cling to the obstruent by the matching of the upper ore-pass passage and the lower ore-pass passage, such that a good blasting effect is ensured; and meanwhile, operating personnel and the explosive substance can be naturally separated from each other by the guide hole, and thus the construction security is ensured. The abovementioned method disclosed by the utility model is simple and practical, and the blockage removal device is simple in structure as well as safe and reliable.
