Abstract：Exploring the application of coal inventory technology in fuel management can improve the phenomenon of fre-quent large deviations in inventory results and reduce the risk of coal reserve management.In order to improve the reliabili-ty of coal inventory results,combining with work practice,the operation procedures of coal inventory were introduced,the operation points of the key links such as density determination,volume measurement,and calculation of coal storage were elaborated during the inventory process.The pressure states of coal pile in coal yard,silo,coal unloading ditch and other coal storage yards were summarized with suitable measurement methods for bulk density.Combining with the specific test data,the relationship between the bulk density of different coal types and the number of roller compaction times was ana-lyzed.It is concluded that the density under the loose state and compressibility of different coal are different greatly,which emphasizes the complexity of coal density measurement and needs comprehensive evaluation and determination.It is pro-posed that systematic research on the application of coal inventory technology in fuel management should be conducted,more research on methods for determining the bulk density of coal piles should be carried out,and experience should be continuously accumulated to provide data and theoretical support for determining the bulk density of coal piles.It is neces-sary to strengthen the management of coal storage sites,upgrade the coal pile volume measurement tools,standardize the operation,and comprehensively improve the working technology and management level of coal inventory.
