Abstract：A new measurement method was developed, that could provide improved measure-ment of loose-coal thermal properties. The method was based on the hot-wire method and could determine thermal conductivity and diffusivity simultaneously. The bulk thermal conductivity was measured by cross hot-wire method while the thermal diffusivity was calculated by numeri-cal methods starting from thermal data taken parallel to the wire. The experiments show that the thermal conductivity and diffusivity measurements are reproducible and agree with the liter-ature values. The maximum deviation only is 0.726%.
