The Design Of Quarry Faces And Slopes | Agg-Net
On a quarry slope formed by three 15m faces at 70° with a minimum bench width of 15m, the reserves lost would amount to approximately 10,000 tonnes per 10m of face when compared with a 7m bench width (fig. 4). When this loss is scaled to actual quarry dimensions, very large quantities of reserves are lost.
