有色金属矿山近年来由於学习苏联先进经验,建立了爆破工作专责制度,广泛地开展了爆破技术的教育,因此使爆破技术水平获得了普遍的提高,爆破方面的人身事故也获得了一定程度的减少,但在爆破工作的点火与起爆方面还是墨守过去的方法与工具,这就障碍了技术水平和安全工作的进一步提高,因此建议做以下的几项改进:一、统一使用具有警戒装置的点燃导火线的器材目前矿山点燃导火线的方法很不一致,东北地区一般是用电石灯,中南地方使用纸捻与废硝化甘油炸药,还有极个别的地方用香烟或线香点燃。使用前一方法虽然在电石灯给水后,能发生强大的火焰,但焰头很不稳定,工人由於在点火中紧张迅 In recent years, non-ferrous metal mines have established a special system of blasting work due to their advanced experience in the Soviet Union and extensively conducted education on blasting techniques. As a result, the level of blasting technology has been generally raised, and personal accidents in blasting have also been reduced to some extent. However, the methods and tools used in the past to ignite and detonate the blasting work have hindered the improvement of the technical level and safety work. Therefore, several improvements are suggested as follows: 1. Uniform use of ignition fuse with a warning device At present, the method of lighting the fuse at mine is very inconsistent. In northeast China, it is usually made of calcium carbide lamps. In southern China, paper twist and waste nitroglycerine explosives are used. There are very few places where cigarettes or incense sticks are used to ignite lights. Although the use of the previous method after the calcium carbide lamps in the water, can produce a powerful flame, but the flame is very unstable, workers due to intense tension in the ignition
