Summary: Polish hard coal mines and copper ore mines operate in deposits located at a depth of 700–1300 meters, where the original temperature of rocks is in the range of 30–50°C. Con- ducting rescue operations at these depths is inherently associated with the risk of overheating the bodies of mine rescuers. Based on an analysis of a typical rescue operation carried out in difficult microclimate conditions, an assessment was made of the currently used methods to reduce the risk of heatstroke among mine rescuers. Based on the results of scientific research on the heat balance of the bodies of workers in deep underground mines, directions for improv- ing methods of determining safe work time limits for rescuers working in hot environments were formulated. The paper presents a computer program for calculating the heat balance of the body of a mine rescuer’s working with the use of typical breathing apparatus. Analysis of the results of sample simulation calculations allowed for the formulation of proposals for tech- nical and organizational measures that can be implemented during the preparation and conduct of a of rescue operations in order to effectively reduce the energy expenditure of mine rescuers and increase the cooling intensity of their bodies. Keywords: mine rescuer, challenging microclimate conditions, breathing apparatus, duration limited exposure, predicted heat strain.
