几年来,我国制造了大量适合于各种起爆条件的起爆器,为电气起爆技术的发展创造了有利条件,特别是高能起爆器问世以来,应用更日趋广泛。我矿经过几年上百次的起爆实践证明,用高能起爆器具有较大的优越性。现将情况简述如下: 一、高能起爆器的原理及特点高能起爆器适用在露天矿、场,金属矿山地下开采及隧道掘进、水利工地等 Over the past few years, China has manufactured a large number of detonators suitable for various detonation conditions, creating favorable conditions for the development of electric detonation technology. Especially since the advent of high-energy detonators, the application has become more and more widespread. After several years of my mine’s detonation practice proved that using high-energy detonator has greater superiority. Now the situation is briefly described as follows: First, the principle and characteristics of high-energy detonator High-energy detonator is suitable for surface mining, field, underground mining and metal mining tunnels, water conservancy sites
