There are two methods usually used for stockpiling are as mentioned here 1. Chevron method (Roof method) 2. Windrow method (Line method) Blending effect by either method is as high as 1: 10. However, the Chevron method is cheaper. The stockpiling of horizontal beds by Chevron method is performed by 1. A belt conveyor with traveling tripper 2.
