Designed as an automatic unit for the removal of overburden and for dumping it onto the inner spoil banks of open cut mines?

• A. Conveyor Bridges
• B. Temporary Bridges
• C. Arch Bridges
• D. Combined Bridges

Answer: (A)

In open-pit mining, moving the overburden efficiently is essential, and a conveyor bridge is built for that exact job. It’s a long, gantry-like structure with a belt conveyor that can span the pit and continuously move material from the mined face to spoil banks inside the pit. This setup enables automatic, uninterrupted removal of overburden, reducing reliance on trucks and improving safety and productivity as the mine advances.

Temporary bridges are for short-term crossings, not for continuous material handling. Arch bridges are static civil structures not designed for conveying bulk ore or overburden. Combined bridges isn’t a standard term for this mining function.
