由于采矿地质条件恶化和缺乏熟练的采矿技术工人,国外有色金属矿山地下采矿技术和工艺改革向提高工作面设备能力、降低采矿工作劳动强度、简化井上下建筑设施、提高生产过程自动化的方向发展。自行设备的应用在继续增长。矿床开拓:越来越多地采用倾斜开拓巷道。采矿方法:由于高效自行风动钻机和牙轮钻机的出现,100～200毫米大孔径炮孔阶段崩落法、垂直倒漏斗后退式采矿法应用日广。凿岩技术:液压凿岩
Due to the deteriorating geological conditions of mining and the lack of skilled mining workers, the underground mining technology and process reform of nonferrous metal mines in foreign countries are of great potential for increasing the capacity of working face equipment, reducing the labor intensity of mining work, simplifying the construction facilities up and down and enhancing the automation of the production process. The use of own equipment continues to grow. Mineral exploration: more and more inclined to open up the roadway. Mining Methods: Due to the highly efficient self-propelled drilling rigs and roller cone rigs, the 100-200 mm large bore hole blasting method and the vertical inverted funnel retracting method are widely used. Drilling technology: hydraulic rock drilling
