It is expected to offer an effective reference to improving the structure strength and reducing design costs.

The coefficient of thermal conductivity and thermal capacity about loose coal are an important foundation parameters of study on the technology of coal spontaneous combustion fire position, and its testing method has been a hotspot of study. For example, In the lab, literature [1, 2] measure the loose thermal conductivity based on the Hot-wire method, and the experimental research carries out on the part of influencing factors about the coefficient of thermal conductivity. Literature [3] measure the thermal capacity about coal based on the water calorimeter method, and the research carries out on the influence of coalification degree, ash content and moisture on thermal capacity. Literature [4] measure the thermal capacity about coal based on the DSC method, and the experimental research carried out on the high temperature heat capacity about coal. The aforementioned method is a single thermal properties of the test method, for the same coal samples, in order to acquire the coefficient of thermal conductivity and thermal capacity, the experiment must be carried many times, but it results in inconvenience. Literature [5] measure the coefficient of thermal conductivity and thermal capacity about loose coal based on the hotline method, and develop a test system. The measurement system introduced in literature [5] is used in this article which gathered the different coal sample to carry on the volumetric heat nature test experiment about loose coal, and then carries out experimental research on the thermal conductivity and influencing factors about the thermal capacity.
