"Longxin No. 1 Electronic Detonator" passed production finalization

On January 14, 2010, the Science and Technology Department and the Safety Production Department of the Ministry of Industry and Information Technology organized the "Longxin No. 1 Electronic Detonator Production Finalization Appraisal and Production Line Acceptance Meeting" in Fushun, Liaoning. More than 20 people including comrades from relevant departments of the Ministry of Industry and Information Technology, heads of the Liaoning Provincial Industry Office, and industry experts and representatives from across the country attended the meeting.

　　 "Longxin No. 1 Electronic Detonator" is a digital blasting equipment with independent intellectual property rights completed by Beijing Uttar Pradesh Company after eight years of research. The finalization of the product shows that my country's internationally advanced detonator products have the conditions for mass production and the basis for popularization. Internationally, this product is called a technological revolution in the engineering blasting industry. The finalized appraisal of "Longxin No. 1" has enabled China's civil blasting equipment industry and engineering blasting industry to enter a new digital era in one fell swoop. The acceptance of the product production line marked the birth of my country's first internationally advanced detonator production line with legal qualifications.

Longxin No. 1 electronic detonator has two-wire two-way non-polar networking communication, online programming and detection capabilities in the hole, which can achieve wide range (0～16000ms), small interval (1ms) delay time in-hole setting and calibration, It can effectively manage the detonation energy, with good detonation accuracy, high reliability, and good use safety. At the same time, it has the characteristics of waterproof, pressure resistance, impact resistance, and environmental protection. The detonator has a built-in product serial number and detonation code, which can realize code authorization to detonate. Built-in anti-interference isolation circuit, safe to use, simple network design, easy to operate and use. The actual engineering blasting application shows that the use of Longxin No. 1 electronic detonator has good controllability, the main vibration frequency of the vibration is controllable, the interference damping effect is obvious, the damage of blasting flying rocks and noise is reduced, the fragmentation is uniform, and the slope remains obvious Reduced, explosive energy utilization efficiency is high, and the comprehensive benefits of engineering blasting are significantly improved.

The experts at the meeting listened to the trial production summary report, safety evaluation report and product inspection report made by the research and development unit, inspected the production and test test of Longxin No. 1 electronic detonator, watched engineering practical videos, reviewed process technical documents and industrial tests Related reports. Unanimously agreed that: Longxin No. 1 electronic detonator process and technical data and drawings are complete, the production process is mature and stable, and the product quality is reliable. They agreed to pass the Longxin No. 1 electronic detonator production finalization appraisal and production line acceptance.
