水电站建设通常包括岩石开挖。岩石种类开挖数量和开挖形状、轮廓,都在工程计划中确定。不消说所有工程都有它们自己的规划。我们不可能找到两个相似的水电站。但是,岩石开挖依赖的众所周知的技术——钻爆法,在基本原则上变化有限,实际应用中却没 Hydropower station construction usually includes rock excavation. The amount of rock excavation and excavation shape, contour, are determined in the project plan. Needless to say that all projects have their own plans. We can not find two similar hydropower stations. However, the well-known technique relied on for rock excavation, the drill-and-blast method, has had only a few changes in its basic principles. In actual practice, however,
