Abstract It is necessary to experimentally measure the coefficients used in the discrete element method （DEM） simulation in order to guarantee the accuracy of the simulation from the source. Therefore， static friction coefficients and restitution coefficients between different burden materials used in the DEM simulation are measured by experiments. The rolling friction coefficients between burden materials are determined by validating the repose angle of the burden. Parameters of burden materials used in the DEM simulation are determined， which provides a database for the accurate DEM simulation.
