Abstract: The need for accurate determination of coal stockpile bulk densities for stockpile tonnages is discussed. A method of bulk density measurement using a Nuclear Depth Density Gauge is explained. Tests on coal stockpiles of known weight using the method are described and the resulting accuracy in terms of stockpile tonnage by volume/ bulk density measurement and weighed tonnage is compared. Work on experimental test stockpiles was carried out by Craven, Elliston and Hayes Pty. Ltd. with the assistance of an Industry Research and Development Board Project Grant and the owners of the stockpile sites, The Electricity Commission of N.S.W., Coal and Allied Industries Ltd and B.C.S.C. Collieries Pty. Limited. The results of this work and its' subsequent and current application on a commercial basis for stockpile tonnage measurement, has shown that coal stockpile bulk densities can be measured, that the accuracy of measurement can be predicted through the use of experimental stockpiles of known weight and greater confidence in the accuracy of stockpile tonnage figures increases the number of ways they may be used.
