Embodiment 1

[0111] Described water starch, wherein the volume ratio of starch and water is 1.5:1;

[0112] 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;

[0113] 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;

[0114] 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;

[0115] Detonate the gas blaster.

Embodiment 2

[0117] Described water starch, wherein the volume ratio of starch and water is 2:1;

[0118] 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;

[0119] 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;

[0120] 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;

[0121] Detonate the gas blaster.

Embodiment 3

[0123] Described water starch, wherein the volume ratio of starch and water is 2.5:1;

[0124] 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;

[0125] 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;

[0126] 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;

Abstract

The invention discloses a blasting method and application of water starch as blasting blast hole tamper. The blasting method includes the steps that a blasting blast hole is filled with the water starch, and a gas blaster in the blasting blast hole is wholly or partially coated with the water starch; the water starch completely seals the blasting blast hole in order to enable the blasting blast hole to be completely filled with the gas blaster; and the gas blaster is ignited. According to the blasting method, shear thickening liquid is used as the blast hole tamper for blocking the blast hole,the blocking effect of the blast hole is good, no slungshot splashing is generated in the blasting process barely, the blasting degree is large, the blasting efficiency is high, the blasting processis gentler, no strong air shock waves are generated, no harm is caused to surroundings and workers, the blasting noise is low, and the blasting process is safe.

Description

technical field [0001] The invention relates to a blasting technology, in particular to a blast hole filling 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 enviro...
