Thermodynamic characteristics of deep space: hot hazard control case study in 1010-m-deep mine

Control of heat hazards in deep tunnels is vital to underground safety production. Taking a 1010-m-deep coal mine as an example, this paper revealed the variation characteristics of geo-temperature along the depth direction in plain area and the variation characteristics of country rock temperature...
