归来庄金矿采矿方法优化与应用

Optimization and Application of Mining Method in Guilaizhuang Gold Mine

归来庄金矿矿体品位负变严重,采用现有采准方法施工脉外运输巷工程量较大,已不再适应生产及经营需求。为降低采准工程量,节省回采成本,通过优化采准工程布置和回采工艺,利用辅助斜坡道,将脉外分段运输巷改为脉内运输巷进行采准,以降低回采成本、提升生产效益。通过实践应用,效果较为理想。

The negative grade changes of Guilaizhuang Gold Mine is severe,and the existing quasi mining method is used to construct out-of-vein transport lanes.In order to reduce the engineering quantity of mining preparation and save the mining cost,by optimizing the layout of the preparation project and the mining technology,and using the auxiliary ramp,the extra-vein segment transport lane is changed into the intra-vein transport lane for preparation,so as to reduce the mining cost and improve the production effi⁃ciency.Through practical application,the effect is ideal.
