The first is by collecting the cross section from the falling coal stream at a transfer point between two conveyors. This is known as Cross-Stream Sampling. The second method is by collecting the primary increment by sweeping the cross section from the material on a single conveyor belt. This is known as Cross-Belt Sampling.
