摘    要：针对山枣岭金矿矿体顶底板破碎,矿石品位低,开采难度大的矿床开采技术条件,通过优化采场结构,采用预留矿柱、锚杆支护等技术措施,有效地控制了矿石贫化,提高了出矿品位,取得了明显的应用效果。

Abstract: Aiming at the deposit mining technical conditions in Shanzaoling gold mine,such as crushed roof and bottom,low ore grade and high mining difficulty,the stope structure is optimized by reserving ore pillar and increasing cable supports.Thus,the ore dilution rate is controlled and the ore withdrawal grade is enhanced.The application effect is obvious.
