摘要
三山岛金矿是我国特大型地采黄金矿山之一,也是地采机械化装备程度最高的黄金矿山。新立矿区原设计采用脉内点柱式上向分层充填采矿法,因上盘矿岩比较破碎、开采难度比较大、矿石贫化损失率比较高,为此设计了独特的上盘进路与下盘水平联合采矿法开采矿石。试验结果表明,这种联合采矿方法不仅在技术上先进、经济上适用,而且安全可靠,可为地质条件相类似的矿山借鉴。
Sanshandao gold mine is one of the oversize under-ground gold mines and the mine with the highest mechanization equipment in our country.The original design of Xinli mining area adopted panel cut-and-fill min- ing method.Because it has more cracked gold ores in the upward lane and huge difficulty for exploring,besides it caused high ore depletion loss ratio.So we designed the unique combined mining method of upward lane and downward horizontal delamination.The test result shows that the combined mining method is an advanced tech- nique,safe and reliable ,and also has high economic applicability.So it can be referenced by other mines who has similar geological conditions.
