The term used for a stockpile created by a radial or telescopic conveyor is?

The term "elongated cone stockpile" is used to describe the type of stockpile created by a radial or telescopic conveyor. This method of stockpiling results in an elongated shape due to the lateral movement of the conveyor while it discharges material. As the conveyor extends and pivots, it deposits aggregates in a manner that creates a conical shape, but elongated, which allows for efficient use of space and material management.

This technique is particularly beneficial when managing aggregates as it allows for larger quantities to be stored while minimizing the footprint required for the stockpile. The elongated cone shape helps in controlling segregation of materials, ensuring a more uniform blend within the stockpile.

In contrast, the other terms presented do not accurately describe the shape or characteristics of the stockpiles created by such conveyors. Flat stockpiles, for example, typically refer to a more even spread of material without the conical shape. Cone stockpiles can denote a more standard conical shape without the elongation aspect, while stacked stockpiles suggest a placement strategy that likely involves multiple layers rather than the one continuous pile created by the radial or telescopic mechanism.
