Geological structure and gas expansion when gas pressure was released can affect the distribution of infrared radiation energy or temperature at coal-rock surface. From this, the foundation of roadway infrared surveying technical was formed. According to the thermodynamic principle of ideal gas and the law of energy conservation, the relation was established between gas gushing amount from coal-rock and air temperature to fall in roadway. At the same time, this paper has analyzed coal-rock density change that geological structure aroused and the change exerted influences on infrared radiation power at surface, as well as, has analyzed the infrared radiation feature of gas gushing at geological structure district. Application results show that infrared survey technology can be used to analyze and forecast the change of coal-rock gas gushing effectively, and to guide the enforcement of the roadway gas project of prevention and handling economically.
