Energy-saving safe blasting method for high-temperature blasting

Abstract

The invention discloses an energy-saving safe blasting method for high-temperature blasting, and belongs to the technical field of blasting. According to the energy-saving safe blasting method, a specially-made heat insulation protection sleeve is arranged, and a water retention cooling sleeve in the heat insulation protection sleeve can effectively prevent cold water from permeating and losing, so that the water consumption is reduced, the waste of water resources is reduced, and the environmental protection performance is improved; a heat insulation cooling cylinder can play a heat insulation role, so that the temperature in a heat insulation cylinder body is far lower than the external temperature, the influence of high temperature in a blast hole on an explosive cartridge is remarkably reduced, and an elastic balloon can repeatedly and spontaneously expand by taking heat transferred into the heat insulation cylinder body as a triggering condition; and each expansion of the elastic balloon can extrude one heat absorption cooling ball into internal cooling water, so that a cooling effect is provided based on the characteristic that saltpeter is dissolved in water and can absorb a large amount of heat, the safe temperature in the heat insulation cylinder body can be kept for a long time, and a worker can have enough time to perform detonation work.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to an energy-saving and safe blasting method for high-temperature blasting. Background technique [0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. When the explosive package or charge explodes in the earth-rock medium or structure, the earth-rock medium or structure will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork engineering, and the demolition of metal buildings and structures. [0003] High-temperature blasting refers to blasting operations in places with high temperatures. High-temperature blasting involves many fields, such as blasting of high-temperature pyrite, blasting of high-temperature rocks in spontaneous combustion coal mines, blasting and shaping of oil and gas well rep...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, it is generally used to inject water into the blast hole to lower the temperature, so that the temperature of the blast hole can be reduced to the safe permissible temperature range of ordinary industrial explosives. The recovery is fast, and it is necessary to quickly charge, fill, and detonate before the temperature of the blast hole rises, resulting in a very hasty blasting process, which will affect the blasting effect and safety; secondly, water injection cooling not only consumes a lot of water but also has low efficiency For areas with poor water resources, it is difficult to find a large amount of water resources, and it is not environmentally friendly and energy-saving
