随着采矿技术的发展,爆破技术也相继发展.露天矿高台阶开采及爆破早在五十年代末和六十年代初在国内外就有过实践,但长期以来高台阶开采爆破技术有许多问题并没有得到解决,其原因之一是因为电铲的最大挖掘高度与开采的台阶高度不匹配,从而导致在采装过程中隐藏着许多不安全因素.笔者通过几年来的实践认为,为保证高台阶 With the development of mining technology, the blasting technology has also been developed one after another.The high-level mining and blasting of open-pit mines have been practiced at home and abroad in the late 1950s and early 1960s, but there are many problems with high-stage blasting technology for a long time One of the reasons for this is that the maximum excavation height of the shovel does not match with the height of the mining step, resulting in many unsafe factors hidden in the process of mining.According to the practice of the past several years, Stairs
