在钻凿中硬和坚硬的矿岩中,使用有气动的、液压的和液压气动联合的冲击-回转式凿岩机。最广泛使用的是气动凿岩机,它们操作简单,可用于不同类型的钻孔设备,这些气动设备的维修量不很大。气动凿岩机的缺点是噪声级高、排出含油的空气灰尘及形成水雾,使掌子面的能见度恶化,压缩空气量消耗,影响凿岩机能量参数的提高,大批量生产的气动凿岩机在生产能力方面,与矿山生产增长的要求不相适应。目前,国内外都致力于完善和生产液压凿岩机,液压凿岩机与气动凿岩机相比有许
In hard and hard rock drilled, pneumatically, hydraulically and hydraulically combined impact-rotary rock drills are used. The most widely used are pneumatic rock drills, which are simple to operate and can be used with different types of drilling equipment, which are not very well serviced. Pneumatic rock drill has the disadvantage of high noise level, the discharge of oil-containing air dust and the formation of water fog, the visibility of the palm face deterioration, the amount of compressed air consumption, affecting the rock drill energy parameters improve the mass production of pneumatic rock drill in terms of production capacity, And mine production growth does not meet the requirements. Currently, both at home and abroad are committed to improving and producing hydraulic rock drill, hydraulic rock drill compared with pneumatic rock drill
