摘要：

广东高要河台金矿云西矿区自2000 年开展采矿方法综合试验以来,采用类框架结构采空区处理技术,即使用人工底柱、人工间柱及三强作业等采矿新工艺,使采矿二次损失贫化降低,出矿品位大幅度提高,目前将要结束作业的2 个中段采矿总损失及总贫化率仅3.58 %与15.27 % ,取得较好技术经济效果。

关键词: 岩金矿床, 浅孔留矿法, 空区处理, 总损失率, 总贫化率

Abstract:

Since Yunxi Mine launched the comprehensive experiment of the exploitation method and adopted the technology of homologous f ramework st ructure and hollow areas disposal (the new technology of artificial jamb , artificial floor and three-powerful operations) in 2000, the reloss and re-impoverishing were reduced and the gold grade was highly improved. Therefore, the will be accomplished 2 levels’total loss ratio and impoverishing ratio were only 3.58 % and 15.27 % respectively as well as the better tech-economy efficiency were gained.

Key words: rocked-gold mine deposit, shallow whole shrinkage stopping, disposal of hollow areas, total loss ratio total impoverishing ratio
