Abstract:According to the latest "Notice of the Department of Safety Production of the Ministry of Industry and Information Technology on Further Promoting the Application of Digital Electronic Detonators", the competent departments of the civil explosives industry in all regions are required to urge enterprises to strictly follow the "14th Five-Year Plan" for the safety development of the civil explosives industry. stop selling industrial detonators other than industrial digital electronic detonators by the end of August". This means that China will bid farewell to ordinary industrial detonators and move towards the era of comprehensive electronic civil explosive industry.

Industrial detonator refers to industrial pyrotechnics with initiating charge and explosives in the tube shell, and is a commonly used initiating equipment in mining and engineering blasting operations. According to the statistics of the China Explosives Industry Association, the sales volume of China's industrial detonators reached a record high of 1.27 billion rounds in 2015, and then with the adjustment of the structure of civil explosive products and the improvement of the level of blasting technology, the medium and deep hole blasting methods are gradually increasing, and the use of industrial detonators is declining year by year, and the sales volume will only be about 972 million rounds by 2020. Since 2016, the state has successively introduced a number of relevant policies to encourage the use of electronic detonators to replace industrial detonators. For example, in December 2018, the Ministry of Public Security and the Ministry of Industry and Information Technology jointly issued the "General Principles for the Information Management of Industrial Electronic Detonators", requiring local public security organs and civil explosive industry departments to vigorously promote the application of electronic detonators.

Electronic detonator, also known as digital electronic detonator, digital detonator or industrial digital electronic detonator, is an electric detonator that uses an electronic control module to control the initiation process. The electronic detonator initiation system basically consists of three parts: the detonator, the encoder and the initiator. Among them, the electronic control module refers to a special circuit module placed inside the electronic detonator, with the functions of detonator detonation delay time control and detonation energy control, built-in detonator identity code and detonation password, which can test its own function, performance and electrical performance of the detonator ignition element, and can communicate with the detonator controller and other external control equipment. Compared with the traditional industrial detonator, the electronic detonator has incomparable safety and control functions, its safety factor is high, the management link is convenient, the social hazard coefficient is low, and the closed management of pyrotechnics can be realized, which is more suitable for the current development trend of the blasting industry.

According to authoritative data, the cumulative output of electronic detonators in 2021 will be 160 million rounds, an increase of 39.7% year-on-year. The proportion of electronic detonator production increased to 18%. By the end of 2022, electronic detonators will be fully replaced by industrial detonators, and it is expected that by 2024, the domestic production license capacity of electronic detonators will reach 1 billion rounds.

At present, the superiority of electronic detonators has been fully reflected, mainly in the following aspects:

01 High security

Electronic detonator ignition powder head and foot wire are connected with electronic control module, by electronic control module control ignition powder head, the structure has good antistatic, anti-stray current, anti-radio frequency and anti-AC and DC characteristics, high safety; Information such as the detonation time must match the actual situation in order to carry out the detonation operation, otherwise the detonation cannot be carried out.

02 High stability and reliability

The electronic detonator initiation system has a complete detection function, which can not only detect a single product, but also detect the entire blasting network, and at the same time can accurately locate the problematic detonator code, solve the relevant problems in advance, and avoid the occurrence of blind guns. In addition, it has good performance advantages such as antistatic, anti-stray current, anti-RF, anti-AC and DC and high precision.

03 Reduce blasting costs and improve blasting effects

The delay setting of electronic detonator is flexible, and the delay accuracy is much higher than that of electric detonator and detonator detonator, which provides the possibility for the realization of differential blasting mechanism, and the utilization rate of explosives can be maximized through the optimization of blasting scheme, and the ideal blasting effect can be achieved, especially in large-scale engineering blasting, which can reduce the comprehensive cost.

04 Reduce blasting vibration

Its flexible delay setting and high precision can realize a reasonable blasting scheme and reduce the hazards of blasting vibration, flying rocks, seismic waves and so on.
