problem experienced when handling coal is flow stoppage. This is a no-flow condition that can result either from arching, also known as bridging, or ratholing. Arching occurs when an obstruction, in the shape of an arch, forms over the silo/bunker/hopper outlet as a result of the material's cohesive strength (Figure 1). Ratholing occurs when a flow channel located above the silo/bunker ...
