Description

Technical Field

[0001] The utility model belongs to the technical field of mining blasting, in particular to a high temperature resistant blast hole interval charging structure. Background Art

[0002] In mining operations, one of the most common operation methods is blasting. When performing blasting, a variety of materials and equipment are required. For example, a blasthole filler is a four-wheel drive loader that is used to fill rock powder into the blasthole. At the same time, it also includes a blasting spacer. The use of a blasting spacer can reduce or even avoid the impact and crushing of ore and rock caused by coupled charges, expand the range of the rupture zone, and improve the effective utilization rate of the explosive blasting energy, thereby reducing the unit consumption of explosives.

[0003] A Chinese patent application (or patent) with publication number CN220729055U discloses an inflatable blast hole spacer, including a capsule, a protective pad fixedly connected to the outer surface of the capsule, a gas generator arranged at the bottom of the capsule, an inner shell arranged inside the capsule, an air column arranged at the center of the inner shell, a movable plate arranged inside the air column, a connecting rod fixedly connected to the outer surface of the movable plate, a connecting block fixedly connected to the bottom of the connecting rod, a fixed seat fixedly connected to the outer surface of the inner shell, and a push rod arranged on the inner wall of the capsule. The utility model arranges a push rod, specifically, drives the movable plate to move downward by a pressure rod, then the connecting rod will press the movable block through the connecting block, and the movable rod will push the push rod to expand, and through the expansion of the push rod, it can ensure that the capsule moves in a vertical manner in the blast hole, avoids the occurrence of deviation, etc., and ensures that the capsule is in a vertical state after inflation and does not tilt.

[0004] The above-mentioned inflatable blasting hole spacer has a fixed block fixedly connected to the top of its capsule, a pressure rod is arranged inside the fixed block, a limit plate is fixedly connected to the outer surface of the pressure rod, and a spring is sleeved on the outside of the pressure rod, that is, the spacer is a pull-type spacer, which results in high operating requirements, incorrect operation will block the hole, and the operation time is long, which prolongs the blasting operation time, resulting in poor work efficiency and long blasting operation time; and, a plurality of movable blocks and movable rods are arranged in the chamber between the inner side of the capsule and the outer side of the inner shell, and connecting components such as movable plates and connecting blocks are added between the movable blocks and the movable rods, which is not only difficult to manufacture, but also extremely costly. To this end, we provide a high-temperature resistant blasthole spacing charge structure to solve the above-mentioned problems. Utility Model Content
