Embodiment 1

[0092] The blasting concentrator uses ordinary TNT explosive packs;

[0093] Excavate a blast hole at the position to be blasted, and place the common TNT explosive pack in the blast hole;

[0094] Pour the mud into the blasting hole where the common TNT explosive pack is arranged, so as to fill the mud between the blasting gun hole and the common TNT explosive pack; wherein, the mud completely seals the blasting gun hole, to completely bury the blasting concentrator in the blasting hole;

[0095] Detonates the blast concentrator.

Embodiment 2

[0097] The blasting concentrator uses gas blasting equipment. For example, in an optional embodiment, CN106643314A can be used. The applicant Guo Yuanjun filed an application on December 21, 2016. , the blaster has the advantages of high power and controllable direction;

[0098] Excavate a blast hole at the position where blasting is to be carried out, and place the gas blasting equipment in the blast hole; pour mud into the blast hole where the gas blast equipment is installed, so that the blast hole and the blast hole The gas blasting equipment is filled with mud; wherein, the mud completely seals the blasting hole, so that the blasting concentrator is completely buried in the blasting hole;

[0099] Detonates the blast concentrator.

Abstract

The invention discloses a blasting method and application of using mud as blockage of blasting blast holes. The method comprises the steps of filling the blasting blast holes with the mud, and using the mud to completely cover or partially cover blasting amplitude transformers in the blasting blast holes; using the mud to completely cover the blasting blast holes to completely fill the blasting amplitude transformers in the blasting blast holes; detonating the blasting amplitude transformers. The blasting method applies the mud as a blast hole blockage material for blocking the blast holes, the blockage effect of the blast holes is good, flying stones and splashing are hardly generated during the blasting process, the blasting degree is deep, the blasting efficiency is high, the method isnot limited to the arrangement of the blasting blast holes, the freedom of arrangement of the blasting blast holes is more flexible, the blasting process is more moderate, strong air shock waves are nor generated, damage to the surrounding environment and workers is not caused, blasting noise is small, and the blasting process is safe.

Description

technical field [0001] The invention relates to a blasting technology, in particular to a blast hole plugging technology. Background technique [0002] Blasting construction, including mining, metallurgy, geotechnical engineering, road, traffic and other blasting projects; dust, earth and rock splashes, noise and shock waves will be generated during the blasting construction process. The shock wave generated by blasting is an external effect produced during the explosion. Within a certain range, the blast shock wave will cause lethality to the construction workers and cause damage to the surrounding buildings. Although the noise produced by blasting is short, it is easy to cause panic to people because of its loud and sharp sound and high frequency. For continuous different explosion sounds, it will cause adverse effects on people's psychology and physiology. Dust, earth and stone splashes produced by blasting will cause certain damage and pollution to the surrounding envir...
