铝热燃烧剂控制爆破(俗称“近人爆破”)由铁道部第二工程局科研所许宁工程师于近年研制成功。为了学习这一新技术,冶炉厂和碎铁厂共同于1979年11月成立了燃烧剂控制爆破试验小组,试验分两个阶段进行。第一阶段以旧混凝土(包括钢筋混凝土)为爆破对象,摸索控制爆破的药物实际配方和施爆规律。共试验了七十三次计233多炮,没出现任何事故,现已基本掌握爆破技术,在公司内推广应用。第二阶段以平炉熔炼室堤坡烧结层和钢渣为爆破对象,于1980年7月在一炼钢厂5 Aluminothermic Combustion Controlled Blasting (commonly referred to as “intimate blasting”) was successfully developed by Xu Ning, a research institute of the Second Engineering Bureau of the Ministry of Railways. In order to learn this new technology, the smelting furnace plant and the iron scraper plant together established a pilot group for the control of the combustion of explosives in November 1979. The experiment was conducted in two phases. In the first stage, the old concrete (including reinforced concrete) was used as the blasting object, and the actual formulation and explosion law of the controlled blasting were explored. A total of 233 shots were fired on 73 occasions. No accidents occurred. The blasting technology has been basically mastered and applied in the company. In the second stage, the sinter layer and steel slag in the open hearth smelting chamber embankment were blasted. In July 1980, they were used in a steelmaking factory.
