Abstract: According to the status that the improved measurement system of loose coal thermal conductivity had more device error sources, which were not conducive to ensured test accuracy, the influence of system hardware error, coal sample self-oxidation exothermic, data processing error and other factors on test accuracy of the thermal conductivity were comprehensively analysed, and then corresponding control measures were raised. The experimental results showed that the system hardware error could be controlled effectively by selecting high-quality test component and controlling heating component size, and the coal self-oxidation exothermic impact can be negligible. The improved measurement system reduced simplified degree of the mathematical model, and solved it through numerical solution, through which can eliminated influence of data processing error effectively.
