Abstract

The invention discloses a method for effectively removing ore-pass blockage and a blockage removal device. The method comprises the steps of calculating a blocking point, drilling a guide hole, setting an explosive substance, and removing the blockage by detonation. 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 the explosive substance. According to the invention, with smart assistance of ore-pass passages matched with an ore-pass, an ore-pass passage above the 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 the 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, therefore, 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 method disclosed by the invention is simple and practical, and the blockage removal device is simple in structure as well as safe and reliable.

Description

technical field

[0001] The invention belongs to the technical field of mining, and in particular relates to a method for efficiently unblocking a chute and a deblocking device. Background technique

[0002] The chute is a transportation facility often used in mines. For high-level ore points, it is very convenient to use the chute to transport ore, and the transportation process does not require power, and the ore can be broken during the transportation process, which is very beneficial for subsequent mineral processing. However, due to the extrusion of viscous large ore or large pieces of mineral material, it is also a frequent occurrence that the mine is blocked. The blocking removal methods in the prior art are methods such as excavation detour, water flushing, soil rocket attack or blasting with long rods to support explosives to the blocking point. These methods can solve some blocking situations, but the construction of tunneling detour and water flushing The difficul...
