Embodiment 1

[0045] The blasting device with hardware timing has its own timing device, which includes the following steps:

[0046] Preparatory steps for equipment installation

[0047] Check the parts of the blasting device and prepare the 3 parts of the carbon dioxide blasting device according to the construction project information. If it is underground or in a mine, it is necessary to dig drainage ditches around, make a good drainage system, take away the surface water in time, and install lifting equipment and arrange them well. Slag out the road, calculate the safety distance, measure the length of the wire, and prepare the wire for blasting. A baffle is provided on the outside of the hole, on the one hand to prevent solid particles from entering the hole, which poses a safety risk during blasting, and on the other hand to prevent solid particles or parts of the blasting device from flying out of the hole during blasting.

Embodiment 2

[0067] The construction technology of software timing is to add timing steps on the basis of hardware timing construction technology, which specifically includes:

[0068] Such as Figure 5 As shown, use the electronic tag 2 reading device to collect the first identification information 5 of the carbon dioxide blasting device 3 with the same delay setting, and obtain at least one segment identification information group 6, the number of segment identification information groups 6 and the number of blasting segments same. For example, the blasting sequence is first at the weakest position in the middle of the roadway section, blasting the inner row of cut holes to form the free surface, and then expanding the blasting outwards, that is, auxiliary eye blasting, and finally performing modeling blasting, that is, peripheral eye blasting, the sequence Using the electronic tag 2 reading equipment to collect the first identification information 5 in the electronic tag 2 on the shell...

Embodiment 3

[0071] Such as Figure 7As shown, a digital carbon dioxide rock-breaking initiation system applied to the method includes a numerically controlled detonator 1, a carbon dioxide blasting device 3 with an electronic tag 2 and an electronic tag reading device 4, wherein:

[0072] The numerically controlled detonator 1 is provided with a detonator processor 10, a power management module 11, a human-computer interaction module 12, an information communication module 14, a self-locking alarm module 15, an ignition control module 16, and an electronic tag reading device 4. The detonator processor 10 is respectively connected to the power management module 11, the human-computer interaction module 12, the information communication module 14, the self-locking alarm module 15, the ignition control module 16, the electronic tag 2 card reader, and the self-locking alarm module 15 is connected to The output end of the ignition control module 16, the charging control module and the safety d...

Abstract

The embodiment of the invention discloses a digital carbon dioxide rock breaking process and a detonation system. The detonation system comprises a numerical control detonator, carbon dioxide detonation devices with electronic tags and an electronic tag reading device. The electronic tags store first identification information of the carbon dioxide detonation devices. Each carbon dioxide detonation device is internally provided with a numerical control device. The numerical control device stores second identification information. The numerical control detonator can read the identification information of the detonation devices. The digital carbon dioxide rock breaking process comprises the steps of assembling of the carbon dioxide detonation devices, installation of the detonation devices,delay setting and detonating. According to the digital carbon dioxide rock breaking process and the detonation system provided by the embodiment of the invention, the electronic tags are additionallyarranged on the carbon dioxide detonation devices to facilitate acquisition of external identification information for the carbon dioxide detonation devices, and information acquisition and information identification are facilitated in the detonation preparation process. Moreover, in an installation-first and segmentation-second manner, the detonation system is used for identifying segments of each detonation device. The error probability is greatly reduced. The detonating effect is ensured.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of carbon dioxide blasting technology, and in particular to a digital carbon dioxide rock breaking technology and a detonation system. Background technique [0002] Carbon dioxide blasting began in the 1950s and began to develop in the United States in the 1980s. It was mainly developed for the coal mining face of high-gas mines to avoid explosion accidents caused by flames generated by explosive blasting. In 2015, with the development of science and technology, domestic manufacturers of carbon dioxide blasting equipment gradually emerged, but currently they are not mature enough and are still in the stage of continuous growth and development. The blasting principle is that carbon dioxide gas can be transformed into a liquid state under a certain high pressure, and the liquid carbon dioxide is compressed into a cylindrical container (blasting cylinder) through a high-pressure pump, ...
