目前国内许多露天矿在设计和生产中采用临近边坡控制爆破技术的还为数不多,然而露天矿边坡产生滑坡的却不少。如核工业部701矿,1972～1978年共发生过6次大小不等的边坡变形破坏,成为影响矿山基本建设的一个突出问题。1981年4月,701矿在395米梯段东部开挖中,应用了预裂爆破技术后,充分显示出它在维护岩体的完整、稳定,使边坡轮廓平整并降低爆震破坏等方面的作用,基本上解决了临近边坡的爆破问
At present, many open-pit mines in the design and production of adjacent slope control blasting techniques are also few, but there are many open-pit slope landslide. For example, in the 701 mine of the Ministry of Nuclear Industry, a total of six times of slope deformation and failure ranging in size from 1972 to 1978 have become a prominent problem affecting the basic construction of mines. In April 1981, in the excavation of the eastern section of the 395 meter long section of No.701 mine, the application of the pre-split blasting technology fully demonstrated that it is complete and stable in maintaining the rock mass, smoothing the slope profile and reducing the detonation damage The role of basically solved the blasting near the slope asked
