Problems solved by technology

[0002] Blast hole blasting, whether it is deep hole blasting or shallow hole blasting, the existing technology has high drilling density and high explosive consumption. Large rocks often appear at the hole opening and backfilling parts, which is not convenient for shipment and processing. Secondary crushing, high blast hole density, and more drilling will increase the operating cost. At the same time, whether it is deep hole blasting or shallow hole blasting, in order to overcome the chassis resistance line, it is necessary to drill ultra-deep holes. Ultra-deep not only increases the amount of drilling , also increased the amount of explosives

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0022] Implementation 1: see figure 1 , In an embodiment of the present invention, a new type of deep hole blasting charge structure includes a blast hole, and the hole of the blast hole has a packing layer 1; the depth of the packing layer 1 at the hole hole is 2.5-3M. The middle of the packing layer 1 is filled with broken drug packs 101, and the thickness of the broken drug packs 101 accounts for 1 / 6 of the depth of the packing layer 1, and the powder is charged at intervals in the packing layer 1, which can effectively reduce packing and reduce Rock bulk rate; along the direction from top to bottom of the depth of the blast hole, it also includes the blasting water bag 2, the first charge layer 3, the second charge layer 4 and the energy-gathering ring 5 at the bottom of t...

Abstract

The invention discloses a novel deep hole blasting charging structure which comprises a blast hole. A hole opening of the blast hole is provided with a filling layer, a blasting water bag, a first charging layer, a second charging layer and a hole bottom energy gathering ring are sequentially arranged in the depth direction of the blast hole from top to bottom, the first charging layer comprises afirst explosive column, the first grain is sleeved with a multidirectional M-shaped energy gathering blast charging device, the second charging layer comprises a second explosive column, and the blasting water bag is filled with carbon dioxide. Compared with the prior art, the novel deep hole blasting charging structure is novel in structural design, good in blasting cutting effect, higher in blasting utilization rate, large in breaking range and uniform in blasting block degree, the blast hole bottom energy gathering ring is arranged at the bottom of the blast hole, the depth of the blast hole is reduced, meanwhile, the rock at the bottom of the blast hole can be completely broken, the operation cost is greatly saved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a novel charge structure for deep hole blasting. Background technique [0002] Blast hole blasting, whether it is deep hole blasting or shallow hole blasting, the existing technology has high drilling density and high consumption of explosives. Large rocks often appear at the hole opening and backfilling parts, which is not convenient for shipment and processing. Secondary crushing, high blasthole density, and more drilling will increase the operating cost. At the same time, whether it is deep hole blasting or shallow hole blasting, in order to overcome the chassis resistance line, it is necessary to drill ultra-deep holes. Ultra-deep not only increases the amount of drilling , also increased the amount of explosives. Ultra-deep is a major hazard for projects where hydropower and nuclear power bases are required to be indestructible. Contents of the invention [0003] The ob...
