摘要
合理的选择爆破参数对最大限度地减小爆破对顶板岩石的破坏、降低贫化率和维护采场顶板的安全有重要意义。针对金山金矿阳山矿段的开采技术条件,利用正交试验方法,对缓倾斜极薄矿脉开采进行了爆破参数优化的试验研究,其结果对缓倾斜极薄矿脉的开采具有重要意义。
In consideration of the technological mining conditions of the gently inclined and very thin ore vein of Jingshan Gold Mine ,blasting parameters were optimized by the orthogonal test. The applied the optimized blasting parameters reduced damage of the roof rock and cut down the dilution of ore.
