在矿山凿岩爆破作业中,长期以来大都采用风动凿岩机。由于经过长期的生产、使用和改进,风动凿岩机已发展成为一种成熟的凿岩工具,得到广泛的应用,并正在向更高效、更先进的方向发展。电动凿岩机发展较晚,我国在五十年代才开始研制,目前全国有不少单位在从事电动凿岩机的研制和生产,近年来有了相当大的进展。如果从能源消耗的角度加以分析,则电动 In mine blasting operations, most of the time, the use of wind-driven rock drill. Due to long-term production, use and improvement, the wind-driven rock drill has developed into a mature rock drilling tool, has been widely used and is being more efficient and more advanced direction. Electric rock drill developed later, China began to develop in the 1950s, at present there are many units in the country engaged in the development and production of electric rock drill, in recent years has made considerable progress. If you analyze from the perspective of energy consumption, the electric
