A variety of stockpiles including wood chips, hog fuel, sand, rock, dirt, or anything else can be measured with only one person. In fact, depending on the shape of the piles, it takes approximately 1-2 hours for a novice user to measure a 100,000 yd3 stockpile. Our experience has shown that one person can measure an entire chip yard
Total Station Stockpile Measurement. SGS professionals use the Total Station method to measure either irregular stockpiles formed by dumping or more controlled stockpiles formed by conveyors. We enter the data obtained by measuring your stockpile in the Total Station data logger, and then download it to a PC to calculate the actual volume.

High grade ore which has been crushed to P80 75 mm, is diverted to a stockpile located near the gravity circuit. Ore is then withdrawn from the stockpile at the rate of 50 tph by one of three vibrating feeders located along a reclaim tunnel. The reclaim conveyor delivers ore to the gravity primary feed conveyor.

If ore is stacked on arrival to a single stockpile, which is built to completion, then the larger the stockpile the more composition variability ...
The ore is mined from an open pit and is friable. Seventy-five percent of the deposit can be mined with dozers and front-end load- ers. The remaining 25 pct must be drilled and blasted. The operation mines and processes 1,500 tons of ore per day. All the material mined is ore there is no waste rock. The mined ore is transported by front-

Stockpile measurement is a technique to measure the volume and weight of commodity stockpiles. It is a scientific instrumental method, using Total Station equipment to determine the volume of the stockpile quantity. Any shape of stockpile can be measured as long as the whole surface is visible. The measurements data from site are
The footprint is the measure that is used to determine whether the stockpile is flat or elevated. Elevated versus flat stockpiles Stockpiles are defined as being either elevated with a height-to-base ratio greater than 0.2, or non-elevated flat with a height-to-base ratio of 0.2 or less.
