Major Mining Strategies Employed at Olympic Dam
The Olympic Dam mine depends on a mixture of mining strategies to extract the ore. The principle strategies employed embody block caving, sub-level caving, and room-and-pillar mining.
Block Caving
Block caving is a bulk mining technique that includes creating a big cave within the orebody, which is then extracted from the underside of the cave. This technique is appropriate for big, layered deposits just like the Olympic Dam orebody.
- Preparation: The orebody is drilled and blasted to create a secure cave flooring.
- Cave Growth: The cave is expanded by drilling and blasting the ore, permitting it to sink below its personal weight.
- Ore Transportation: The ore is transported by a sequence of tunnels to a processing plant.
- Residue Administration: The cave flooring is designed to be robust sufficient to help the remaining ore and permit for secure entry for future mining phases.
Sub-Stage Caving
Sub-level caving is a variant of block caving that includes making a sequence of sub-levels, or horizontal slices, within the orebody. This technique is appropriate for deposits with complicated geology or a number of ore varieties.
- Sub-Stage Design: The orebody is split into sub-levels, every with its personal cave.
- Ore Extraction: The ore is extracted from every sub-level, utilizing a mixture of drilling, blasting, and conveyor programs.
- Residue Administration: The sub-levels are designed to be secure and help the remaining ore, permitting for secure entry for future mining phases.
- Cave Growth: The sub-levels are expanded by drilling and blasting the ore, permitting for simpler entry to deeper ranges.
Room-and-Pillar Mining
Room-and-pillar mining includes extracting ore from a sequence of small rooms, or chambers, whereas abandoning a sequence of pillars to help the roof. This technique is appropriate for deposits with complicated geology or a number of ore varieties.
- Room Design: The orebody is split into small rooms, every with its personal extraction sequence.
- Ore Extraction: The ore is extracted from the room utilizing a mixture of drilling, blasting, and conveyor programs.
- Pillar Design: The pillars are designed to be robust sufficient to help the roof and permit for secure entry for future mining phases.
- Residue Administration: The pillars are designed to be secure and help the remaining ore, permitting for secure entry for future mining phases.
