Abstract

Mining method optimization was conducted in Sanshandao gold mine to increase mining productivity,and stage open stoping and upward-layered combined mining method was proposed.The stage open stoping and upward-layered combined mining method plays very important role in increasing efficiency of trackless equipment.Cable anchor pre-support and crown pillar bolt wire mesh support were used in major fault F1 on the hanging wall to ensure the working safety.Upward-layered and fill method was used for panel pillar recovery.To minimize the exposed area,hanging wall support pillar was left for recovery at the final stage of stope panel.The practice shows that the sublevel stoping and upward cut and fill combined mining method has the advantages of small degree of development,large production capacity,high efficiency and safety.
