A low-temperature rapid blasting device

Abstract

The invention discloses a low-temperature rapid blasting device. The low-temperature rapid blasting device comprises a power and master control device, a rapid cooling and punching device, a rapid explosive loading device and a pneumatic lifting device, wherein the power and master control device, the rapid cooling and punching device and the rapid explosive loading device are all fixed on the pneumatic lifting device, and the power and master control device is electrically connected with the rapid cooling and punching device, the rapid explosive loading device and the pneumatic lifting devicerespectively. The low-temperature rapid blasting device is an automatic punching, explosive loading and blasting integrated device, rapid punching can be achieved in the punching process, uniform andcontinuous cooling of a drill bit and a blasting hole is realized, the discharge efficiency of an excavated object is improved, and pollution-free punching is ensured; and meanwhile, the filling efficiency of explosive powder can be improved in the explosive loading process, the blocking explosive powder is prevented from blocking the blasting hole, so that the safety of workers is guaranteed, waste of the explosive powder in the filling process is avoided, the blasting safety and the blasting effect are further guaranteed, and thus the blasting operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of blasting devices, in particular to a low-temperature rapid blasting device. Background technique [0002] my country is the country with the largest coal production and consumption in the world. In coal blasting projects, whether it is large-scale blasting or small-scale blasting, it is necessary to use punching equipment to punch holes in appropriate positions before placing powder and detonators. Implement blasting in the hole. However, in the coal mining area, due to the influence of coal spontaneous combustion or high formation temperature, the blasting operation conditions become more complicated. Sometimes the high temperature or the internal spontaneous combustion of the explosives after drilling and charging can easily cause premature explosion or abnormal blasting. , often brings engineering disasters. At present, in order to prevent the occurrence of the above accidents, technicians need to take out the ...

However, in the coal mining area, due to the influence of coal spontaneous combustion or high formation temperature, the blasting operation conditions become more complicated. Sometimes the high temperature or the internal spontaneous combustion of the explosives after drilling and charging can easily cause premature explosion or abnormal blasting. , often brings engineering disasters

At present, in order to prevent the occurrence of the above accidents, technicians need to take out the drill bit after drilling with the drill bit, then clean the drill hole, and then use cooling equipment to fill the drill hole with some cooling gaseous or liquid substances to achieve the purpose of cooling. Make the inside of the drill hole drop to the appropriate temperature for explosive storage, but this operation has many steps and is cumbersome to operate, and rapid blasting cannot be achieved

[0003] In addition, in recent years, people have gradually begun to use automatic charging devices to replace manual work. However, in the prior art, when the drug fluidity of the drug charging device is poor during the charging process, it is very easy for the drug particles to interfere with each other. However, the phenomenon of accumulation and blocking of the through hole causes serious leakage and underfilling of medicines. At this time, manual inspection and refilling are required, so the use effect is not good, and the filling efficiency has not been significantly improved.

In addition, since the explosives are all in powder form, it is very easy to generate dust during the feeding process, which not only pollutes the environment, but also easily affects the health of the staff.
