摘要
详细介绍了淘锡坑钨矿采用人工假底替换传统采场底柱技术的工程试验,结果证明:当采场底柱品位较高采用人工假底技术时,具有施工简单、安全可靠和降低采矿损失率的优势,不仅可多回收资源,其经济效益也十分明显。
the paper introduces engineering test of artificial false bottom replacing traditional stope sill pillar technology in Tao Tin Pit tungsten mine, the result shows： when artificial false bottom is adopted for stope sill pillar with high grade, the simple, safe and reliable construction can be carried out and mining loss percentage can be reduced, not only resources can be recovered, but the economic benefit is obvious.
