Based on 44 documented demonstration projects worldwide, a novel conceptual aspect of
mine-oriented low-enthalpy geothermal exploitation classification was initially proposed. For …

As the shallow mineral resources are nearly depleted, the mining of deep resources has
become an urgent problem to be studied. The increase in mine depth can lead to the …

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 …

Mine geothermal energy has been recognized as “heat hazard”, which is harmful to the
health of miners and causes disasters. In order to realize the transformation of mine …

A novel method for deep mine cooling based on using backfill containing phase change
materials (PCMs) was verified by numerical simulations and experiments. A laboratory-scale …

In order to address the issue of high temperatures and thermal damages in deep mines, the
factors causing downhole heat damage at high temperatures were analyzed, the mine …

As the underground engineering proceeds to a greater depth, the thermal stresses resulted
from high-temperature surrounding rock become a major challenge for the deep …

The research on mine geothermal energy exploitation has attracted global interest for many
years. This paper proposes an innovative new method for geothermal-coal synergetic …

Based on the similarity theory, this paper conducts a dimensionless analysis of air flow and
selects Archimedes number as the similarity criterion number in order to study the cooling …

Heat damage caused by high ground temperature is becoming a bottleneck restricting deep
mining. The thermal insulation material is a heat damage prevention method that can …
