The spatiotemporal evolution patterns of thermal environment in fully mechanized caving faces of deep mine

Thermal Science
With the increase in mine depth, the original rock temperature rises under the influence of the geothermal gradient. High temperature surrounding rock heat dissipation leads to an increase in working face temperature, seriously affecting mining production safety. Using distributed fiber optic temperature measurement to study the thermal characteristics
