Alternatives to Pushbacks in Strategic Planning

In mine planning, pushbacks are commonly used to expand operations and bring additional resources into production. However, Dr. Bright Oppong Afum discusses several alternatives that can provide strategic advantages depending on the site conditions and operational goals.

One alternative is the development of satellite pits, smaller pits located around the main pit. This approach can maximize resource extraction while offering flexibility. However, satellite pits come with limitations in terms of depth and slope angles, which must be carefully evaluated through scenario analysis to determine their feasibility.

Another key alternative is transitioning from open-pit to underground mining, particularly in areas with depth limitations. Methods such as caving can be employed by driving declines into the orebody, allowing for more efficient extraction of deeper resources without the extensive costs associated with larger pushbacks.

Automation and robotics present a modern solution to operational challenges posed by pushbacks. The integration of autonomous drilling, loading, and hauling systems can optimize space utilization and improve efficiency in constrained mining environments. Automation allows mining operations to reduce equipment size and adapt to limited working areas, ensuring continuous material handling without the need for costly contract mining.

In conclusion, alternatives to pushbacks—such as satellite pits, underground mining, and automation—offer flexible solutions for strategic mine planning. Evaluating these options can help optimize operations, enhance efficiency, and maximize resource recovery.
