Helically coiled tube heat exchanger (HCHE) was extensively used to enhance the thermal
environment of deep underground space. The inefficiency of heat transfer in the mine …

The provision of mechanical cooling in deep mines comes with a significant energy cost as a
significant amount of heat transfers from surrounding rock to the airflow. Thermal insulation …

The temperature distribution is one of the most vital parameters which should be fully
considered in high geothermal tunnel design. For the purpose of studying the impact of …

Studying the effect of the seepage of cryogenic fluid on the surrounding rock temperature of
the tunnel of the high-temperature tunnel is important to ensure the surrounding rock stability …

Miners in underground space often experience discomfort and heat strain due to
combination of hot-humid environment and strenuous physical intensity. To investigate the …

The study of fluid‐heat coupling in deep fractured surrounding rock is the basis of design,
safety, and extraction of geothermal energy of deep underground spaces. The heat transfer …

In order to solve the heat damages in deep mines, a cool-wall cooling technology and its
working model are proposed based on the principles of heat absorption and insulation in …

To study the mechanism of unsteady heat-moisture transfer of wet surrounding rock in deep
mining, a series of experiments with different initial and boundary conditions were carried …

With the gradual depletion of shallow coal resources, mines gradually turn to deep mining,
and the problem of high temperature and heat damage gradually emerges. In order to study …

The article compares the climate conditions in an excavation with thermally insulated roof
and sidewalls to the conditions when such insulation is absent. The analysis of the …
