Calculating Stockpile Capacity

The conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by: 3.14 (Tan A)R³ D/3000 = capacity in metric tons…………………(1) where: R = stockpile radius in meters A = angle of repose for material to be stockpiled D = density of material in kg/m³ Note that the capacity of the conical stockpile varies with the cube of the radius of the pile. This means that the capacity of the conical pile grows very rapidly as the height (and hence the radius of the pile) incr
