摘　　要：瑶岗仙黑钨矿床经过上百年的开采已即将闭坑,因此决定开发建设裕新多金属矿。针对裕新多金属矿的开采技术条件,比较确定了露天开采方式,并进行了5个境界方案的技术经济比较,最终确定了坑底标高为324 m的最优境界(境界剥采比为5.17 t/t)。优化分析后的最终露天境界为瓜瓢形,可采出矿量3288.89 t,平均剥采比为3.26 t/t。After hundreds of years of mining,the black quartz tungsten deposit of Yaogangxian was going to finish mining.Thus,a new mine named Yuxin polymetallic ore was decided to exploit. According to the mining conditions of Yuxin polymetallic ore,the open-pit mining was determined. Through technical and economic comparison on five schemes of pit limit,the optimal scheme that the bottom elevation was 324 m and the stripping ratio was 5. 17 t / t was determined. After optimization analysis,the open-pit limit was finally shaped as gourd ladle,and the expected ore capacity was 3288. 89 t with average stripping ratio of 3. 26 t / t.
