Abstract: High temperature and high humidity is a main type of disaster faced by long-distance high-temperature driving roadway.In order to solve the problem of long-distance high-temperature single-roadway excavation in the demand for cooling,we put forward local refrigeration cooling program to achieve the effect of roadway cooling method.The west wing of the main water discharge roadway was selected as the research object,based on the influence of the temperature and humidity field of the driving roadway on cooling effect,numerical simulation study was carried out,revealing the long driving roadway air flow temperature field's change rules and heat damage formation mechanism,to ensure the safe production of driving roadway.
