Abstract:

The mine is technological expansion project，the original 600 000 t/a production scale expantion to 2. 1 million t/a.  The work was clone to take full advantage of existing eduipment，play eduipment efficiency so that a reasonable match with each other between the original eduipment and existing eduipment meet the needs of the open stope mining engineering.  It can also reduce ore loss and dilution，improve mining economic effects，so that the total amount of eduipment and mine stripping production capacity match.  Large一scale eduipment can be used.  The optimized selection of mining and transportation equipment in the open pit is a reference for similar mine equipment selection.

Key words: open pit mine, equipment selection, refinement mining
