光面爆破是在普通爆破法基础上发展起来的,而且由光面爆破又演变出另一种爆破——预裂爆破,它们都属于控制爆破。光面爆破在国内不仅在井巷洞室、地下构筑物,而且在水工、隧道建筑中也已广泛成功地使用。我矿经过基本建设和生产,有的采区台阶已临近采场境界,甚至有的地段(如南山头采区)距最终边坡线只剩几米了,用普通中孔爆破后将严重破坏边坡。为保持采场边坡稳定,台阶坡面平 Smooth blasting is developed on the basis of the normal blasting method, and another blasting - presplit blasting evolves from the smooth blasting, all of which are controlled blasting. Smooth blasting in the country not only in cave caverns, underground structures, but also in hydraulic, tunnel construction has also been widely used successfully. I mine after basic construction and production, and some mining area steps are near the mining field, and even some lots (such as Nanshan Tau mining area) from the final slope line only a few meters, with the ordinary hole blasting will severely damage the edge slope. In order to keep the stope slope stable, the step slope is flat
