![]() ![]() of Stockpile Volume of Mineral Excavated in Open Pit. To fulfill this need, HTG developed a materials calculator using common measurements. Diameter known Diameter (D) ft Length (L) ft Angle of Repose (A) deg Height (H) ft Volume cubic ft Bulk Density lbs/ft3 Tonnage Tons (short) 2. sufficient for this application, namely volume calculation, analogue to (Tucci et al., 2019). The actual stockpile volume from the mill operator is 265.4 m 3 and is used as a standard for the statistical comparative analysis. I am currently attempting to calculate an approximate measurement for the volume lost around the sides of the stockpile. Materials Calculator Whether excavating a trench or a hole for a tank or foundation, or stockpiling materials such as gravel or soil, there is often a need to make a field estimation of volume and weight. The drone yielded an estimated stockpile volume of 258.7 m 3 while the traditional tape method yielded an estimated stockpile volume of 262.0 m 3. ![]() There is lost volume on the top (from around the cones – see diagram) and around the sides of the stockpile in areas around the cones. The angle of repose (the angle that the ore settles to the horizontal) of the ore is also known, as is the maximum stockpile height.Īn ‘ideal’ stockpile would have a flat top and sides.It is demonstrated in the attached diagrams that due to the nature of cone-ply stacking, this is not the case. ![]() The stockpile has a limited width and length. The aim is to maximise the capacity of the stockpile, within a given space. I am in desperate need of some help with a materials handling problem which i am stumped on more specifically on calculating the volume of a stockpile that is built from a series of cones ('cone-ply')Ī cone-ply built stockpile is built with a series of cones (see diagram). ![]()
