Description

Technical Field

[0001] The invention relates to the field of digital electronic detonators and engineering blasting, and in particular to a large-load networking method and a digital electronic detonator blasting method. Background Art

[0002] With the continuous advancement of my country's supply-side structural reform, the development of the mining blasting engineering industry has gradually shifted towards specialization and large-scale development. Among them, large and medium-sized mining projects have developed significantly and are gradually becoming a trend in the development of the mining industry.

[0003] With the development of mining blasting technology, digital electronic detonators have become an important part of mining blasting and have been widely used in various types of mining blasting scenarios. Digital electronic detonators can not only improve blasting efficiency but also reduce safety risks during blasting. At the same time, the scale of blasting requires an increase in the number of digital electronic detonators. At present, the project solves this problem by cascading multiple detonators, but this brings disadvantages such as networking stability and operational complexity.

[0004] The traditional detonator cascade networking mode can no longer meet the needs of blasting projects well, because the traditional cascade mode cannot use a main detonation line to connect all gun areas and cannot use a single detonator for detonation control. There are many network branches and many controllers, which bring communication interference and inconvenient operation.

[0005] Therefore, in order to meet the development needs of blasting in large mines, this field urgently needs a large-load networking method. Summary of the invention

[0006] One of the purposes of the present invention is to provide a large load networking method to solve the above problems.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a large-load networking method, using network connecting lines to connect all electronic detonators in the gun area in parallel in one or more network connecting lines, and then using a detonation main line to connect the gun area with the large-load detonation controller.

[0008] As a preferred technical solution, for multiple gun areas using ≤1000 electronic detonators, if the distance between adjacent gun areas is <50m, each gun area uses a network connection line to connect all the electronic detonators in the gun area in parallel in one or more network lines, and then uses the network connection line to connect adjacent gun areas together in series, and finally uses a detonation main line to connect to a large-load detonation controller.

[0009] As a further preferred technical solution, the connection positions between the multiple gun areas are the head and tail between the gun areas or the shortest distance between the gun areas.

[0010] As a further preferred technical solution, for adjacent gun areas with a distance of ≥50m, it is advisable to use a separate detonation main line to connect the gun area with the large-load detonation controller.

[0011] A second object of the present invention is to provide a method for controlling detonation using the above-mentioned large load networking, which comprises the following steps: (1) Divide the entire engineering blasting area into several blasting areas according to the blasting plan; (2) Each gun area shall arrange a number of blast holes according to the blasting plan and place the required number of electronic detonators, which shall be connected in parallel in one or more network lines. The number of electronic detonators in the gun area shall be determined according to the blasting plan. It is preferred that the number of electronic detonators carried in a single gun area shall be ≤ 800. (3) Use a large-load detonation controller to scan, input, set the delay time, and conduct network testing on the digital electronic detonators arranged in the gun area; (4) Use the detonation main line to connect the gun area with the large-load detonation controller and issue timing commands to all electronic detonators in the gun area detonation network; (5) Charging the electronic detonators in the detonation network through a large-load detonation controller; (6) A detonation command is issued to the electronic detonators in the detonation network through a large-load detonation controller, and the electronic detonators are detonated according to the set delay time.

[0012] It can also be detonated through a large-load detonation controller cascade detonation control device, and the operation process is consistent with the current detonator cascade control detonation process.

[0013] As a preferred technical solution, in step (3), for gun areas that are ≥50m apart and a single gun area that carries ≤400 electronic detonators, a conventional detonation controller can be used to scan, input, set the delay time, and perform network detection on the electronic detonators in the gun area, and then generate a QR code containing the network data, which can then be scanned by a large-load detonation controller to import the electronic detonator network data.

[0014] This networking method is also compatible with the existing cascade networking mode; This networking method is suitable for large open-pit mines with a large number of electronic detonators (≤1000 rounds) per unit, regardless of the mine type or blasting method. This networking method can effectively solve the communication instability caused by the detonator cascade networking mode currently used in engineering projects: using a single detonator controller improves the anti-interference ability; at the same time, by reducing the number of branches in the detonator network, the clutter interference in the network is reduced; This networking method is used with a large-load detonation controller for detonating digital electronic detonators (load quantity ≤ 1000 rounds. It should be noted that all detonators cannot be purchased at will. They have separate numbers and need to be filed. Their output voltages must be adapted and adjusted). It is compatible with conventional products, and the electronic detonators at the end of the network can ignite reliably. This networking method effectively solves the problem of insufficient number of electronic detonators carried by a single detonator for a single large artillery area. There is no need to use multiple detonators to scan and network the electronic detonators in the artillery area separately. There will be no discrepancy between the number and identity information of detonators in the line network and the number and identity information of detonators in the detonator network. This networking method can connect several adjacent artillery areas in series and use one main detonation line for network detonation. There is no need to pull the main detonation line for each artillery area separately. A single detonation saves 200 to 300 meters of network line, thereby saving costs.

[0015] Compared with the prior art, the present invention has the advantages that: the present invention provides a networking method that can realize the recording, detection, timing and detonation of electronic detonators with only a single detonation controller, and the networking method has the advantages of high stability, simple operation, diversity, large load quantity, etc. Specifically: This networking method only requires a single detonator to realize the input, networking, timing, detonation and data uploading of 1000 rounds (the standard of existing technical conditions is set as 1000 rounds) of electronic detonators, with high operating efficiency; Compared with the traditional cascade mode, this networking method is more stable and reliable in the communication link; This networking method has various connection modes, is convenient and efficient, does not limit the blasting mode and is compatible with the current cascade networking mode; This networking method can save the operation time of personnel at the blasting site and the cost of using the detonation main line.
