Embodiment 1

[0061]Water starch is used as the shear thickening liquid, and the volume ratio of starch and water is 1.5:1; the blasting concentrator uses ordinary TNT explosives; dig blasting holes at the position where the blasting is to be carried out; add the starch into the water and stir evenly , after about 5-15 minutes, prepare the water starch, pour the water starch into the blast hole, place the ordinary TNT explosive bag in the blast hole, push the ordinary TNT explosive bag into the water starch; The water starch completely seals the blast hole so that the blast concentrator is completely buried in the blast hole; fill the outer side of the water starch near the blast hole outlet side with 10 cm blasthole mud; A cardboard is arranged between the mud and the water starch; the ordinary TNT explosive pack is detonated.

Embodiment 2

[0063] Water starch is used as the shear thickening liquid, and the volume ratio of starch and water is 2:1; the blasting concentrator is made of ordinary TNT explosives; the blasting hole is excavated at the position to be blasted; the starch is added to the water and stirred evenly , after about 5-15 minutes, prepare the water starch, pour the water starch into the blasting hole, place the ordinary TNT explosive package in the blasting hole, push the ordinary TNT explosive into the water starch, the Said water starch completely seals said blasting hole, so that said blasting concentrator is completely buried in said blasting hole; fill 5cm of blasting mud outside the water starch near the blasting hole outlet side; said blasting A cardboard is arranged between the mud and the water starch; the ordinary TNT explosive pack is detonated.

Embodiment 3

[0065] The shear thickening liquid is water starch, wherein the volume ratio of starch and water is 2.5:1; the blasting concentrator is made of ordinary TNT explosives; the blasting hole is excavated at the position to be blasted; the starch is added to the water and stirred evenly After about 5-15 minutes, the water starch is prepared, and the water starch is poured into the blast hole,

[0066] Place the common TNT explosive pack in the blast hole, push the common TNT explosive pack into the water starch; the water starch completely seals the blast hole, so that the blast concentrator is completely buried in the blast hole In the blasting hole; fill 5 cm of blasting mud outside the water starch near the outlet of the blasting hole; a cardboard is arranged between the blasting mud and the water starch; detonate the ordinary TNT explosive package.

Abstract

The invention discloses the application of shearing thickening liquid as blasting hole blockages, and the shearing thickening liquid completely coats or partially coats the blasting energy accumulatorin the blasting hole; the blasting process comprises the following steps of: filling shearing thickening liquid in a blasting hole, wherein the shearing thickening liquid completely coats or partially coats the blasting energy accumulator in the blasting hole; the shearing thickening liquid completely closes the blasting hole so as to completely bury the blasting energy accumulator in the blasting hole; detonating the blasting energy accumulator. According to the invention, no flying stone splashing is generated during the blasting process,, the blasting degree is deep, the blasting efficiency is high, the blasting effect is not limited by the arrangement mode of the blasting hole, and the degree of freedom of the blasting hole arrangement is greater; the blasting process does not generate strong air shock waves, does not cause damage to the surrounding environment and the staff, has small blasting noise and blasting process is safe.

Description

technical field [0001] The invention relates to a blasting technique, in particular to the application of a blasthole plug. 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 env...
