Preliminary study into a mechanized resue mining

2009-8-27 · The best way to describe the mining method is to consider astrike gully approximately 60 metres long that will beadvanced on an apparent dip in an up dip direction. Thestrike gully or resue face is sized to take mechanizedequipment and will always include the reef to be mined and asection of footwall waste. Working from an existingexcavation, which encompasses the reef and extends into thefootwall, the reef in the sidewall of the gully is drilled,blasted into the gully and cleaned. The waste in the sidewallof the gully is drilled, charged up and blasted simultaneously.With the use of millisecond delays, the waste is initiated firstand thrown into the gully creating backfill. After the wastehas moved, the reef is popped down. The next step is to loadthe reef
