地下凿岩和露天穿孔是矿山 和岩石工程中的第一道生产工序。它直接影响劳动生产率的提高和生产成本的降低，因此对其设备技术水平的提高，各方面都给予了高度重视。特别是近几年来，随着科学技术的飞速发展，国外凿岩（穿孔）设备已明显呈现以下发展态势：一是设备向大型化发展
Underground rock drilling and open-air drilling are the first production processes in mines and rock works. It has a direct impact on the improvement of labor productivity and the reduction of production costs. Therefore, the technical level of its equipment has been given high priority in all aspects. Especially in recent years, with the rapid development of science and technology, overseas drilling (perforating) equipment has clearly shown the following trends: First, the equipment to large-scale development
