Embodiment 1

[0040] like figure 1 As shown, this embodiment provides a thermal insulation device for pyrolysis cannon blasting equipment, which includes a thermal insulation cylinder 1 , an insulating liquid 2 and a sealing cover 3 .

[0041] like figure 1 As shown, the side wall of the heat insulation cylinder 1 includes a constraining layer 4 and a liquid-holding layer 5 arranged sequentially from outside to inside, further, the constraining layer 4 includes a strength layer 6 and an adhesive layer arranged sequentially from outside to inside 7.

[0042] The heat insulation cylinder 1 is cylindrical, one end of which is open, and the other end (opposite to the opening end) is sealed and connected with the sealing cover 3, the opening end is the upper end of the heat insulation cylinder 1, and the end sealingly connected with the sealing cover 3 is the insulation. The lower end of the thermal cylinder 1, and the interior of the thermal insulation cylinder 1 has a cavity for placing expl...

Embodiment 2

[0051] like Figure 1 ~ Figure 3 As shown, this embodiment provides a blasting method, which is implemented based on the device of the above-mentioned embodiment 1, and includes the following steps:

[0052] Step 1: Use the positioning rod 10 to measure the depth of the blast hole 11 of the pyrolysis gun.

[0053] Step 2. According to the depth of the blast hole 11 of the pyrolysis gun, select a heat insulating cylinder 1 with a depth greater than the depth.

[0054] Step 3: Cover the lower end of the heat-insulating cylinder 1 with the cover 8 to cover the sealed end of the liquid-holding layer 5 and the lower opening end of the constraining layer 4 , and the folded edge 13 is closely pasted to the side of the constraining layer 4 .

[0055] Step 4, according to the depth of the blast hole 11 of the pyrolysis gun, calculate the charge depth of the blast hole 11 of the pyrolysis gun, the charge amount of the emulsion explosive 12 and the length of the detonating cord 13, and ...

Abstract

The invention discloses a high-temperature solution bomb blaster heat isolating device and a blasting method. The device comprises a heat isolating cylinder, a heat insulation fluid and an opening sealing cover; one end of the heat isolating cylinder is opened, and the other end is in sealing connection with the opening sealing cover; the inner part is provided with a hollow cavity for placing bomb and a detonating cord; heat insulation fluid is located in the hollow cavity of the heat isolating cylinder, and the side wall of the heat isolating cylinder comprises a restriction layer and a fluid holding layer which are orderly arranged from outside to inside; both ends of the restriction layer are opened, one end of the fluid holding layer is opened while the other end is sealed; the sealing end of the fluid holding layer is located at one end of the heat isolating cylinder in sealing connection with the opening sealing cover; the restriction layer comprises an intensity layer and a bonding layer which are arranged in order from outside to inside. The high-temperature bomb blaster heat isolating device is simple in structure, low in cost, and convenient to operate; the high-temperature solution bomb blaster heat isolating device can be used for protecting bomb and the detonating cord, thus the blaster can be safely used in high-temperature solution bomb, the processing time limit of large solution bomb under high temperature is solved; the blaster can be attached with adjacent bomb zones to explode at the same time, thus the blasting cost is saved.

Description

technical field [0001] The invention relates to a heat insulation device, in particular to a heat insulation device and a blasting method for pyrolysis cannon blasting equipment, belonging to the field of high temperature blasting heat insulation. Background technique [0002] In my country's Shanxi, Inner Mongolia, Ningxia and other places, there are a large number of spontaneous combustion coal mines, which lead to high temperature of surrounding rock, and the local temperature can reach more than 700 °C. At present, drilling and blasting or mechanical strong excavation are mainly used to deal with high-temperature surrounding rocks. Among them, drilling and blasting is mainly for hard rock, and mechanical strong excavation is mainly for soft rock. Among the two, drilling and blasting is the main method, and then mechanical coal is extracted. Affected by the high temperature of the surrounding rock, there are a large number of cracks in the surrounding rock, the drilling i...
