Embodiment 1

[0108] Water starch is selected as the shear thickening liquid, wherein the volume ratio of starch to water is 1.5:1;

[0109] Add the starch into the water and stir evenly. After about 5-15 minutes, the water starch is prepared, and the water starch is poured into the blast hole;

[0110] Place the gas blaster in the blast hole, push the gas blaster into the water starch; the water starch completely seals the blast hole, so that the gas blaster is completely buried in the blast hole In the blast hole; for example, in an optional embodiment, CN106643314A can be selected. The applicant Guo Yuanjun filed an application on December 21, 2016. Powerful, and at the same time the advantages of controllable direction;

[0111] Fill the outer side of the water starch near the blast hole outlet side with 5cm of blasting mud; a cardboard is arranged between the blasting mud and the water starch;

[0112] Detonate the gas blaster.

Embodiment 2

[0114] Water starch is selected as the shear thickening liquid, wherein the volume ratio of starch and water is 2:1;

[0115] Add the starch into the water and stir evenly. After about 5-15 minutes, the water starch is prepared, and the water starch is poured into the blast hole;

[0116] Place the gas blaster in the blast hole, push the gas blaster into the water starch; the water starch completely seals the blast hole, so that the gas blaster is completely buried in the blast hole In the blast hole; for example, in an optional embodiment, CN106643314A can be selected. The applicant Guo Yuanjun filed an application on December 21, 2016. Powerful, and at the same time the advantages of controllable direction;

[0117] Fill the outer side of the water starch near the blast hole outlet side with 5cm of blasting mud; a cardboard is arranged between the blasting mud and the water starch;

[0118] Detonate the gas blaster.

Embodiment 3

[0120] Water starch is selected as the shear thickening liquid, wherein the volume ratio of starch to water is 2.5:1;

[0121] Add the starch into the water and stir evenly. After about 5-15 minutes, the water starch is prepared, and the water starch is poured into the blast hole;

[0122] Place the gas blaster in the blast hole, push the gas blaster into the water starch; the water starch completely seals the blast hole, so that the gas blaster is completely buried in the blast hole In the blast hole; for example, in an optional embodiment, CN106643314A can be selected. The applicant Guo Yuanjun filed an application on December 21, 2016. Powerful, and at the same time the advantages of controllable direction;

[0123] Fill the outer side of the water starch near the blast hole outlet side with 10cm blasting mud; a cardboard is arranged between the blasting mud and the water starch;

[0124] Detonate the gas blaster.

Abstract

The invention discloses a blasting method and application of using shear thickening liquid as blockage of blasting blast holes. The method comprises the steps of filling the blasting blast holes withthe shear thickening liquid, and using the shear thickening liquid to completely cover or partially cover gas blasters in the blasting blast holes; using the shear thickening liquid to completely cover the blasting blast holes to completely fill the gas blasters in the blasting blast holes; detonating the gas blasters. The blasting method applies the shear thickening liquid 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, theblasting efficiency is high, the method is not limited to the arrangement of the blasting blast holes, the freedom of arrangement of the blasting blast holes is more flexible, the blasting process ismore 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...
