Thermal Insulation of Excavations and Its Effect on Climate Conditions

The article compares the climate conditions in an excavation with thermally insulated roof and sidewalls to when such insulation is absent. analysis of temperatures presented consisted limiting heat transfer from rock mass heading one Polish coal mines. It widely believed that thermal sidewalls, through which fresh air supplied, can substantially improve conditions. article’s objective evaluate impact on surface reduction strata a high virgin temperature mine air. Preventing existing hazard involves higher costs extraction, whereas consequences inadequate prevention threaten health or life miners.
