Comprehensive understanding of the airflow temperature field in a high-temperature tunnel
is critical for the deep underground engineering project. In this paper, we establish a two …

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 influx of hot water will intensify the detrimental effects of heat and humidity during the
excavation of high geothermal tunnels. The spatiotemporal evolution of the ambient …

The heat dissipated from high geo-temperature underground surrounding rocks is the main
heat source of working faces, while thermal water upwelling and trickling into the roadway …

Deepening our understanding of temperature and stress evolution in high-temperature
tunnels is indispensable for tunnel support and associated disaster prevention as the rock …

Fog in mine air intake roadways is a non-negligible disaster that seriously reduces the
visibility of the roadway, affects vehicle transportation and the safe passage of personnel …

As the number of tunnels continues to increase, there are more and more tunnels crossing
the high geothermal strata. This study aims to address the issue of heat damage caused by …

To address the delamination and water leakage caused by the fracture of insulated chilled
water pipeline (ICWP) in the process of long-distance drilling through deep strata, a new …

Deep‐circling thermal water upwelling and trickling to high geo‐temperature roadway
obviously alter the microclimate in mines, which brings difficulty to the prediction of airflow …
