摘要
张坝沟石灰石矿长期采用光面爆破技术来减小爆破震动及后冲对固定边坡的危害。文中较详细的介绍了矿区地质条件、光面爆破的设计及施工中的问题,对倾斜孔非对心不耦合装药边坡爆破的效果进行了评价,建议采用多种控制目的的穿孔工作方法。
Perimeter blasting technique, which can decrease the blasting vibration and harmfulness on fixed slope, is used in the Zhangbagou Limestone Mine. The geological condition, the design of perimeter blasting and the issue of construction are introduced in detail in the paper. The author evaluates the result about the non-coupling loading slope blasting, and suggests the mine adopt multi-dominated - aim drilling method.
