ChatThe 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) increases. Increasing the height of the stockpile by 26% results in a doubling of the stockpile capacity. One should also observe at this point that onehalf of the capacity of the stockpile is in the lower 1/5 of the pile. This fact will become important later in considerations of live storage capacity. For many common materials, the angle of repose, A, is about 38 degrees. Substituting this value for A reduces Equation 1 to: 8.18 x 10 4 R³D = capacity in metric tons.(2) In English units

The elongated stockpile and its variations are the most common stockpile form in high capacity installations. The capacity of the stockpile can easily be determined by considering the pile as two separate volumes. The end half cones can be combined to form a single conical pile which can be analyzed using Equation 1, 2 or 3 above. The capacity of the center section of the elongated pile is given by: R²LD Tan A/1000 = capacity in metric tons(4) where: R = radius of end half cone in meters L = length of center section in meters D = density of material in kg/m³ A = angle of repose for material to be stockpiled For a value of A of 38 degrees, Equation 4 reduces to: 7.81 x 10 4 R²LD = capacity in metric tons..(5) Equation 5 expressed in English units is: 3.91 x 10 4 r²ld = capacity in short tons.(6) where: r = radius of end half cone in feet l = length of center section in feet d = density of material in lb/ft³ The total capacity of an elongated pile is

In the discussions above, only the total capacity of the stockpiles was considered. This capacity is useful if reclaiming is done with a front end loader or if a bulldozer or bucket wheel reclaimer is used. Usually, the figure for total stockpile capacity is utilized when planning for the longest scheduled shutdown. In that circumstance, one should expect to use a bulldozer to obtain complete stockpile reclaim so that the stockpile will not be any larger than necessary. With belt conveyors in normal operating circumstances, one should work with the live storage capacitythat is, the portion of the stockpile that will flow into the feeders in the reclaim tunnels without dozing of the pile. The portion of the stockpile outside this live storage section is referred to as dead storage. Obviously, the following analysis does not apply when a front end loader is used for reclaiming. In this discussion, we will consider only a linear arrangement of outlets under a conical stockpile. Elong
