针对吉戈庄金矿原有采矿方法存在的回采贫化率高、顶板安全性差和生产成本高等问题,根据该矿的实际情况,提出了顺路斜道菱形单元全面削壁充填连续采矿法和斜长壁工作面矿岩分采房柱空场采矿法.通过技术比较和综合经济比较得出:全面削壁充填连续采矿法采场顶板安全性好,采准布置简单,采切比小且采矿损失率小,采矿贫化率低.最终,确定顺路斜道菱形单元全面削壁充填连续采矿法为适合吉戈庄金矿开采的较优方案.该方法的使用可避免遗留采空区,提高采场安全性,而且能够充分发挥选厂的工作效率,从而提高矿区经济效益.

The mining method of Jigezhuang gold mine which increasing the mining dilution rate,mining risk and production cost is unsuitable.Aiming at these problems,two new mining methods are proposed according to the practical situation,which is resuing stoping and room and pillar open stoping.By technical and economic comparison,the resuing stoping is chosen,because the method decreases the stripping ratio,dilution rate and mining loss,improves the roof safety and simplify the stope layout.In this way,the goaf of the mine will be decreased,which will achieve greater security.The usage of this mining method will also improve the plant efficiency and economic benefits.
