Anti-leakage package for bulk explosives and construction method

Abstract

The invention relates to a package 4 for bulk explosives used in a porous mine or a porous object to be exploded, and the package is put into a blast hole 1 and can effectively prevent the bulk explosives from leaking into cracks or a karst cave. The anti-leakage package for the bulk explosives is made of anti-flaming antistatic soft materials, a conductive coating is coated on the inner surface of the anti-leakage package, and static accumulation in the construction process of explosive filling is avoided. An anti-leakage package frame rotation disc 6 for the bulk explosives is driven by a weight 5 to rotate and conveys the package to the bottom of the blast hole. The anti-leakage package for the bulk explosives is simple in structure, is convenient to operate, and guarantees the uniformity of the explosives inside the blast hole.

Description

technical field [0001] The patent of the invention relates to the packaging and construction method used to prevent explosive leakage during the blasting construction process of multi-porous mines or multi-porous explosive objects. Background technique [0002] During the blasting construction process, due to the impact of the previous blasting, cracks will be generated in the blasted objects. In many mines, especially limestone mines, there are many cracks or caves. If the blast hole passes through cracks or caves in the blasted object, when the explosives are loaded into the blast hole, the explosives will seep into the cracks or caves, resulting in uneven distribution of the explosives in the blasted object. If the charge height is guaranteed and the charge amount is increased, the unit consumption will be too high, and a blasting accident will occur; if the charge amount is not increased, the areas outside the cracks or caves will be very blocky, and the expected blasti...

Problems solved by technology

If the blast hole passes through the cracks or caves in the blasted object, when the explosive is loaded into the blast hole, the explosive will penetrate into the crack or cave, resulting in uneven distribution of the explosive in the blasted object

If the charge height is guaranteed and the charge is increased, the unit consumption will be too high, and a blasting accident will occur; if the charge is not increased, the area outside the cracks or caves will be very large, and the expected blasting effect will not be achieved.
